Ext4 is the default system for most Distros. Have snapper to create pre/post BTRFS and LVM snapshots. 1 fell slightly short of the Linux file-system performance. Silent data corruption, sometimes referred to as bitrot, is more. NTFS Benchmarks Continuing on from yesterday's Linux 4. "Open-source" is the primary reason people pick Btrfs over the competition. Data integrity protection. a lot of btrfs' perception of 'breaking' is actually due to checksums (correctly) finding fault on a users data and (correctly) not allowing mounting of the filesystem until it's fixed. 또한 ext3. It's solid and tested and I'm not sure I see any benefit to another file system there. XFS与Ext4性能比较. Small_Light_9964 • 1 yr. . Here are the major feature of BTFS over ext4. ) XFS. Its OS comes with only one by default (mostly it’s NTFS, FAT 32, or HFS). EXT4 is better in the general case. . For the adventurous: you can define block devices on btrfs and use ext4 on those block devices (ext4 on btrfs). While RAID 5 and 6 can be compared to RAID Z. 4TB HDD formatted as NTFS for backuping all other three hard disks. I've set up and used btrfs for years and later zfs for the past few years both professionally and on home servers. XFS does not require extensive reading. The Ext4 file system is a very old file system and it has been used on the Linux operating system for a long, long time. Utilice. Phoronix has a ton of reviews, Google for them. It is backward-compatible with older versions of Ext. F2FS vs. EXT4 is functional and is considered more stable. 6. Overview of File Systems in Linux. XFS vs. FreeBSD has ports you can install that will allow data transfer of some linux file systems. BtrFS is still very experimental and is not recommended for a production server or desktop environment. Ability to create large volumes of up to 1 PB 1. - No RAID. Note that while these tests are not indicative of real-world performance, we can extrapolate these results and use this as one reason. As well as btrfs. It does its job well. 00GHz (8 Cores) MSI C236A WORKSTATION (MS-7998) v1. You can easily backup each distro without filling your disk using snapshots. However, if you are looking for a. Btrfs Benchmarks comparison, here is a wider look at mainline file-systems on the Linux 4. XFS 和 ext4 的比较. Файловая система Ext4 это улучшенная версия Ext3, которая, в свою очередь, не что иное, как переработанная Ext2. . ZFS is great but heavy/complex, and lack of block pointer rewrite can be painful. This is because BTRFS is optimized for handling small files, while EXT4 can struggle with multiple small files due to its delayed allocation. So I think you should have no strong preference, except to consider what you are familiar with and what is best documented. The XFS File System. No compression, but compaction. Both are good file systems. En el caso de los servidores NAS de Synology, tenemos la posibilidad de configurar EXT4 o Btrfs, de hecho, en el asistente de configuración de los volúmenes podremos elegir entre uno y otro sin ningún problema. In this test, Btrfs outperformed LVM in every benchmark. But none of these will be relevant to a bog standard use case like "browsing the internet and sometimes. There’s very little difference between EXT4 and XFS, both in total throughput and behavior over time. F2FS vs. Per the recommendation from RedHat: Another way to characterize this is that the Ext4 file system variants tend to perform better on systems that have limited I/O capability. On multi-drive systems, the opposite might be true, zfs outperforming ext4. SSD Disk Observations. 84 nvme drives split up into a small ext4 volume and the rest is btrfs. BTRFS VS EXT4 performance in Raid 1. 두 파일. that said, current Tumbleweed builds disable COW for those subvolumes. In terms of XFS vs Ext4, XFS is superior to Ext4 in the following. Example 2: ZFS has licensing issues to Distribution-wide support is spotty. EXT2/3/4: Extended Filesystem is by far the most popular filesystem among Linux desktop installations. EXT4 vs. XFS is spectacularly fast during both the insertion phase and the workload execution. In this article, we will have a look at deeper details at these file systems comparatively including EXT4 vs XFS, EXT4 vs EXT3, BTRFS vs EXT4 as well as ZFS vs EXT4. Được tích hợp vô hệ thống DSM Synology , do NAS có hiệu xuất làm việc cao trong vấn đề lưu trữ và khôi phục, Btrfs hoạt động trên NAS. OpenSUSE hiện sử dụng btrfs làm tùy chọn mặc định cho phân vùng /root, nơi đặt hệ điều hành. 1 Overview of File Systems in Linux. Reviews of EXT4, EXT3, XFS, BTRFS, and ZFS. EXT4 being the “safer” choice of the two, it is by the most commonly used FS in linux based systems, and most applications are developed and tested on EXT4. Btrfs is the recommended file system to use in most scenarios. 0 SSD drive used was a 250GB Samsung 850 PRO solid-state drive connected both via SATA and then a SATA. 1 million iops for ext4, right in line with the spec of the drive times 2,. Bcachefs is a copy-on-write (COW) file system for Linux-based operating systems. 4 EXT4 / XFS / Btrfs RAID Performance On Four HDDs Storage : 2019-12-28: Benchmarking The Experimental Bcachefs File-System Against Btrfs, EXT4, F2FS, XFS & ZFS Storage : 2019-06-25: Optane SSD RAID Performance With ZFS On Linux, EXT4, XFS, Btrfs, F2FS Storage : 2019-06-20: Linux 5. 여러 가지의 HDD를 장착하여 사용을 하신다면 사진이나 중요한 자료들을 저장하는 드라이브에는. EDIT 1: Added that BTRFS is the default filesystem for Red Hat but only on Fedora. Như vậy, chúng ta có thể dễ dàng kết hợp các phân vùng định dạng Ext2, Ext3 và Ext4 trong cùng 1 ổ đĩa trong Ubuntu để tăng hiệu suất hoạt động. In most cases that’s EXT4, but for Fedora, OpenSuse and maybe a few others it’s btrfs. 7 - EXT4 vs. On a slow Linux box with an ext4 filesystem, the same operation takes less than a second. Tl;dr: The best filesystem for Unraid. g. We’ll go over each file system in more detail ahead. Installing and booting with BTRFS has its advantages too. I hear zfs is good too. 0 as well as with the help of stock mount options. Ext4 is probably the final evolution of the ext filesystem (which started with ext, then ext2, ext3, and now ext4). The XFS file system is loved in the Linux community for its ability to handle and manage significant. file-system comparison, here are some fresh benchmarks looking at the Btrfs, EXT4,btrfs is also slower in some benchmarks but I very much doubt thats visible in normal use. 创建 btrfs 文件系统 6. Another way to characterize this is that the Ext4 file system variants tend to perform better on systems that have limited I/O capability. Btrfs vs ext4 . 再將資料再回存到 NAS, 這部份會花費很多時間. What we mean is that we need something like resize2fs (ext4) for enlarge or shrunk on the fly, and not required to use another filesystem to store the dump for the resizing. 4. 84 nvme drives split up into a small ext4 volume and the rest is btrfs. Ext4, Btrfs, and XFS are three widely used file systems in Linux. Btrfs was 107% faster in initial read scores and 24% faster in initial write scores. exFAT is the best choice at the moment. Ext4 fs can read and write to Ext2 or Ext3 file systems, but the Ext4 it is not compatible with Ext2 and Ext3 drivers. but for the shared servers with many users you might consider xfs for the parallel IO and number of files. ZFS is open source, it isn't "owned" by Oracle. Probably those edge cases are not visible on an external USB hard drive, could be visible with external SSDs on a USB3. At least on 13. I'll be going RAID 6. 4 HDD RAID performance per his request with Btrfs, EXT4, and XFS while using consumer HDDs and an AMD Ryzen APU setup that could work out for a NAS type low-power system for anyone else that may be interested. I've never had an issue with either, and currently run btrfs + luks. Btrfs has been a stable part of the Linux kernel since 2013, and you can reformat your hard drives using the file system today. EXT4: Alternative File Systems for Linux Operating Systems. 0. Btrfs on SSD, XFS on HDD. But not enough users follow the guide on and instead do stuff that actually makes the system worse. In the end I use ext4 as trustworthy frontend, and btrfs as a unreliable backup. It's rigid and inflexible. The result of XFS is often more than three times lower than ZFS in this benchmark, and the difference with Btrfs and EXT4 is greater. So I moved everything off of it and formatted it into XFS and ate the 0,5% space loss for peace of mind. File-systems tested on the NVMe SSD included Btrfs, EXT4, F2FS, XFS, and NTFS. There won't be any noticeable difference. . 8 snapshot as of last week. Btrfs Benchmarks comparison, here is a wider look at mainline file-systems on the Linux 4. Btrfs is a bit slower with writes because of its Copy-on-write nature, but just as fast when it comes to reads. Use XFS for your array drives and Btrfs for your cache pool. It lived enough, time to move on. F2FS vs. Language: Format: Red Hat Training. Ext4 파일 시스템. Ext4 tiene el registro en diario de forma predeterminada y es probable que los nuevos usuarios no sepan cómo deshabilitarlo para guardar lecturas / escrituras en sus. ZFS vs EXT4 vs BTRFS file systems File systems like ZFS, EXT4, and BTRFS may seem strange or. 7. But EXT4 is mature, rock solid, and completely reliable, and the standard for most of the linux world. XFS vs. 7. Tích hợp Cloud Station Server, Drive mang hiệu quả cao. If you're looking to warehouse big blobs of data or lots of archive and reporting; then by all means ZFS is a great choice. Approach 1: Build your own kernel, and tweak it's build config to pre-link btrfs. The total throughput is better than with ZFS (40k vs 60k), but the jitter is more severe. Uma das decisões que você tem que tomar quando vai instalar qualquer distro Linux é o Sistema de arquivos do Linux! São vários para escolher, EXT4, XFS e BTR. ran defragment utility to compress all existing files. From what I read. zfs or btrfs or ext4. Each one might work for you based on YOUR needs! Supp. XFS is a robust and mature 64-bit journaling file system that supports very large files and file systems on a single host. However, BTRFS had significantly better performance with small files than EXT4. The main thing is to use latest Linux kernels to avoid old kernel Btrfs implementation. org and zfsonlinux. Since then I have come to value tooling about as much as performance. これらのファイルシステムはEXT4、Btrfs、ZFSであり、XNUMXつのファイルシステムは異なる特性を持ち、いくつかは異なるシナリオでより優れたパフォーマンスを発揮します。 外部4. 4 EXT4 / XFS / Btrfs RAID Performance On Four HDDs Storage : 2019-12-28: Benchmarking The Experimental Bcachefs File-System Against Btrfs, EXT4, F2FS, XFS & ZFS Storage : 2019-06-25: Optane SSD RAID Performance With ZFS On Linux, EXT4, XFS, Btrfs, F2FS Storage : 2019-06-20: Linux 5. Ext4 is built on older technology, so it lacks modern file-system features found in systems like E2FS and BtrFS. When comparing XFS vs EXT4, XFS also offers unlimited inode allocation, advanced allocation hinting (in case you need it), and, in recent versions, reflink support. XFS, EXT4, and BTRFS are file systems commonly used in Linux-based operating systems. There are results for “single file” with O_DIRECT case (sysbench fileio 16 KiB blocksize random write workload): ext4 1 thread: 87 MiB/sec. In a few words, I just need a really reliable and fast filesystem for years ahead, with the care of SSD in mind, I need it mostly for gaming, video-audio production, working with a lot of small/medium files (from 100-500Kb to 100-150Gb) sending them. So now I can boot up into a snapshot. Ext4 is the fourth version of the Ext (Extended) File System for Linux and is probably the most well-known file system for Linux out there. btrfs is da bomb yo. However, we also must admit that Btrfs has many advantages that Ext4 doesn’t have, for example:The question is XFS vs EXT4. All of these Linux. But they come with the smallest set of features compared to newer filesystems. It was later developed for Linux. 2 See what others are saying What is btrfs? Btrfs, which stands for B-tree file system, is a modern and advanced file system that supports many features, such as snapshots, compression,. This is an issue for those like me who have older laptops e. I have 6 disks so I have created 3 logical disks, 2 SSDs each - just for testing. Both filesystems provide COW but XFS fragments less (and it's data cow only so no snapshots, only reflinks). We believe that btrfs has the correct feature set and roadmap to serve Ceph in the long-term, but XFS and ext4. Approach 2: Readjust things so the kernel and modules are on an ext4 filesystem and the data you most want to compress is on a btrfs partition. • 3 mo. Is XFS better than btrfs? September 30, 2023 by Garry. However benchmarks test quite narrow parameters which may not be reflected by running an OS. We may have lengthy talk on ext vs XFS vs f2fs and btrfs vs zfs and there are many more points to be mentioned, but for regular users. It you have huge hard drives, BTRFS supports up to 16 times larger size than 1 EXT4 partition. Una vez que hemos conocido las principales características de EXT4, vamos a hablar sobre Btrfs, el que se conoce como sucesor natural del sistema de archivos EXT4. Interestingly, the first version of the Ext4 filesystem, the Extended filesystem (“Ext”), came out in 1992 for the Minix OS. Using Btrfs, just expanding a zip file and trying to immediately enter that new expanded folder in Nautilus, I am presented with a “busy” spinning graphic as Nautilus is preparing to display the new folder contents. With not having the time to conduct the usual kernel version vs. ago. Features of the XFS and ZFS. The BTRFS RAID is not difficult at all to create or problematic, but up until now, OMV does not support BTRFS RAID creation or management through the webGUI, so you have to use the terminal. with mirrored pairs, you also have the option of. 2. To have best performance use noatime mount option, and I also recommend to use mount option. But according to tests in all scenarios, XFS is better than EXT4, it's a pity that there are no tests in games. Share. EXT4 vs. If you are using Ext2 or Ext3, you can convert the partition to Ext4. 3. It's boring, not flashy, and just stable, which is exactly what you want for the root partition. The way you describe this workload, I think it is not very demanding. I understand if I use zfs/btrfs i will miss out on any data redundancy features but maybe pick up some added features like better consistency, snapshots, ect or should I just stick with ext4. 3. Diferenças básicas entre o Ext4 e o Btrfs. GameStop Moderna Pfizer Johnson & Johnson AstraZeneca Walgreens Best Buy Novavax SpaceX Tesla. As well as ext4. Btrfs is expected to offer better. ago. e. • 3 mo. Both Btrfs and Ext4 have their own advantages. As cotas XFS não são uma opção remountable. 7. F2FS With Linux 4. XFS has a few features that ext4 has not like CoW but it can't be shrinked while ext4 can. Phoronix: Linux 4. EarthyFeet. NTFS OpenBenchmarking. BtrFS looked promising, but last I checked it still couldn't be trusted in RAID modes. I'd say ext, because it is faster, and because you asking means, that you don't know how to use btrfs features, otherwise the choice is obvious: need snapshots -> btrfs, need reflinks -> XFS, default -> ext4. Here are a few other differences: Features: Btrfs has more advanced features, such as snapshots, data integrity checks, and built-in RAID support. Considering that the btrfs will be able for spanning over the multiple hard drives, it is a very good thing that it can support 16 times more drive space than the ext4. Also I've thought about btrfs again. ext4 was supposed to be a stop gap until a better Linux filesystem came along. I don't know anything about XFS (I thought unRaid was entirely btrfs before this thread) ZFS is pretty reliable and very mature. 5. Between 2T and 4T on a single disk, any of these would probably have similar performance. So now I can boot up into a snapshot. ext4 with m=0 ext4 with m=0 and T=largefile4 xfs with crc=0 mounted them with: defaults,noatime defaults,noatime,discard defaults,noatime results show really no difference between first two, while plotting 4 at a time: time is around 8-9 hours. because it spans multiple partitions, it's less likely to fill up your hard drive. In Windows NTFS is used, while in Mac OS it is HFS, perhaps these will sound familiar to you, especially the typical FAT or its variants for. I'ved tested compress=off/lz4, dedup=on/off and serveral Cache/Log constellations on 256GB SSD. It has features that can scale better than ext4 and is even preferred over ZFS by some users. If, for example, most your data writes are file add (like storing your camera roll, your movie collection,etc), btrfs snapshots will use virtually no extra space. Additional mount points using Btrfs will also have corresponding subvolumes created based on the Name field. The one they your distribution recommends. 3. El ext4 y xf. 356 Btrfs—short for "B-Tree File System" and frequently pronounced "butter" or "butter eff ess"—is the most advanced filesystem present in the mainline Linux kernel. As for filesystems, not sure I'd bother considering JFS since I believe it may be deprecated out of the kernel soon. I see that it says multiple btrfs snapshots are not supported. It also recovers from power failure easily, with the journaling system. BTRFS is a filesystem with an architecture and a set of features that are similar to ZFS and with a GPL license. I've heard good things about BTRFS, and I'd use XFS but I dislike that it takes an significant % of the free-space off the bat. One of the main reasons the XFS file system is used is for its support of large chunks of data. mount the recently formatted btrfs partition without special options just with mount /dev/nvme0n1p2 /mnt and create the subvolumes you want, e. If you are concerned about your data integrity, as you clearly are, then use ZFS. Dropping performance in case with 4 threads for ext4 is a signal that there still are contention issues. Now Fedora just needs to implement it properly like openSUSE. (當然另一種做法是新增硬碟, 另外格式化為 btrfs. The XFS one on the other hand take around 11-13 hours!With Bcachefs on its trek towards the mainline Linux kernel, this week I conducted some benchmarks using the very latest Bcachefs file-system code and compared its performance to the mainline Btrfs, EXT4, F2FS, and XFS file-system competitors on both rotating and solid-state storage. For example it's xfsdump/xfsrestore for xfs, dump/restore for ext2/3/4. Además, el rendimiento en una sola unidad giratoria generalmente tendrá la unidad como el eslabón más débil. . 5. Rep: XFS has unbalanced performance, but in the best use case blows away many other formats. 7. Btrfs provides checksums for data and metadata, ensuring enhanced data integrity. Ext4 has some scalability and performance issues when dealing with large or fragmented files or directories. EXT3 이후 나온 EXT4는 기존 버전보다 안정성은 향상이 되었지만 범용성과. Each file system has its own advantages and disadvantages. Ext3 and ext4 have some very specific differences, which I'll focus on here. 0 hard drive when using EXT4 and XFS. XFS vs Btrfs. So I did two rounds: the. In today's video, we will talk about the 4 Major Linux File Systems. File-systems tested on the NVMe SSD included Btrfs, EXT4, F2FS, XFS, and NTFS. the mirrored pairs would be much faster for both reads and writes. Tính năng sao chép dữ liệu. By far, XFS can handle large data better than any other filesystem on this list and do it reliably too. A maximum. Btrfs trails the other options for a database in terms of latency and throughput. I remember being on ext4 using Timeshift but it only supports rsync–so slow. Same as with ZFS. To mount the XFS file system so that it uses the external journal, specify the -o logdev=device option to the. XFS vs EXT4!This is a very common question when it comes to Linux filesystems and if you’re looking for the difference between XFS and EXT4, here is a quick summary:. Both Btrfs and Ext4 have their own advantages. I haven't benchmarked the performance but as a user on a modern desktop/laptop system with fast ssd, f2fs vs btrfs didn't show any. XFS vs. But unless you intend to use these features, and know how to use them, they are useless. FYI: btrfs. But timeshift reports (maybe due to different sizes of the combined btrfs) as reported in my initial. Which is better largely depends on opinion. EXT4 lacks more robust features but is stable and well-supported on all Linux operating systems. Linux 5. For the Proxmox host, if you install it and use LVM-thin as root pool option in the Proxmox installer, it will automatically make a root partition in EXT4. Linux EXT4/Btrfs RAID With Twenty SSDs Storage :. Recommend. btrfs sub cr /mnt/@ (the @ alone is the convention for "root directory" in btrfs) btrfs sub cr /mnt/@home. XFS vs. Unfortunately you will probably lose a few files in both cases. Page 2 of 2. Resizing (growing) is possible with btrfs and xfs. Tùy chọn mặc. No such built-in compression support is in Ext4. wbeater • 3 yr. Januar 2020. ) TL, DR: All 3 major next gen CoW file systems have their advantages and drawbacks, and I figure integrating them into my workflow is the only way to fairly evaluate them see how they work for myself. . EXT4 is just a file system, as NTFS is - it doesn't really do anything for a NAS and would require either hardware or software to add some flavor. ago. In the case of the Intel 900p SSD, the XFS results were too fast to accurately measure while EXT4 and F2FS took just two seconds to complete while Btrfs took six seconds. Here are some key differences between them: XFS is a high-performance file system that Silicon Graphics originally developed. Ext4 is the default system for most Distros. 1. For a side-by-side feature comparison of the major file systems in SUSE Linux. Both are suitable for everyday use, but it's worth noting that ext4 partitions. Not only does both file systems feature a more robust data assurances then XFS (the mature fsck for Ext4 and checksums and data. It can create, diff and restore snapshots and provides timelined auto-snapping. That being said, it is meant as a temporary solution to migrate data to a native Unix file system, such as ZFS or UFS. My recommendation of that list would be XFS. XFS doesn't have any RAID, while Btrfs RAID is not yet completely stable and is in its early days. Já que muitos usuários Linux, que desejam experimentar o novo sistema, vêm do Ext4, faz sentido enumerar alguns pontos que realçam as diferenças entre os dois: O Ext4 ainda é a melhor escolha, no desktop do usuário comum — por ser mais rápido na transferência de arquivos e por ser mais maduro6,861. Yes Ext4 is much easier to setup but BTRFS has its advantages. BTRFS, ZFS, XFS, and EXT4 File Systems – Complete Comparison. With disks as fast as NVMe you probably won't notice much difference in drive speeds between btrfs, f2fs, ext4, etc unless you have some extremely disk-bound workload. Even if you do notice. Ext2 → Ext3 → Ext4. . The only benefit of btrfs that I could find was marginally easier setup and the software license. Windows has always been terribly slow to update, say, all file permissions in a large directory structure. That was many years ago, perhaps when btrfs was less ready. XFS and btrfs are two advanced file systems for Linux that offer significant improvements over ext4. The fastest for the SATA/USB tests was XFS followed quickly by EXT4 and then F2FS. BTRFS. showed that at the time the performance for the RAID setup was not able to compete with ext4 and ZFS. It you have huge hard drives, BTRFS supports up to 16 times larger size than 1 EXT4 partition. XFS. Use XFS for your array drives and Btrfs for your cache pool. 3TB HDD formatted as NTFS for main files. With ZFS ZVOLs, you can run other file systems like ext4 or xfs for special situations (like as storage for VMs) and still get snapshots/block checksumming. BTRFS is newer, and the performance is not as good in many cases, but it is not far off. BTRFS have some fancy features, and could help you manage your disk better in some automation-future-proof way. use ZFS only w/ ECC RAM. If you're truly after space with no redundancy then you might as well go RAID0 or no raid at all with only two drives. Hello everyone, I can't choose proper filesystem between XFS, ZFS (OpenZFS), BTRFS, F2FS and EXT4. (2013) compared the performance of Btrfs against XFS and ext4. XFS. EXT4. Installing and booting with BTRFS has its advantages too. To be clear, I am using RAID0 with two SSDs with strip size of 256Kb. , power failure) could be acceptable. the COW which saves alot of space and increases the speed. SSD optimization. So it has no barring. But I would still refrain from using it on the deck due to the case folding trouble. In the time since I chose ext4 for these systems, btrfs seems to have come a long way, so the choice may be harder today. 4 To 4. , power failure) could be acceptable. Btrfs（技术预览）" Collapse section "6. When running PostMark, ZFS came out far ahead of the UFS file-systems being more than ten times faster than. File Size: Ext4 supports file size up to 16 TiB, while Btrfs. This pre-dates xfsprogs 3. Btrfs has been a stable part of the Linux kernel since 2013, and you can reformat your hard drives using the file system today. Picking a filesystem is not really relevant on a Desktop computer. Die Funktionen umfassen eine transparente Komprimierung, Prüfsummen und. Edit: fsdump / fsrestore means the corresponding system backup and restore to for that file system. A daily snapshot of Ubuntu 19. 0 X. as @Neoon pointed out ext4 (on your mdraid) works just fine, for that you can rather discuss the usage of raw vs qemu, which driver (virtio, scsi,. Using multiple drives of varying sizes created a luks1 encrypted ‘single’ data and dup meta volume. For anything with higher capability, XFS tends to be faster. If you're on HDD and you need the ability to shrink the fs, then use EXT4, but you lose any COW benefits. Ext4 specially without a journal and XFS are both extremely fast. Yves Trudeau. Written by Michael Larabel in Storage on 20 January 2018. - no encryption. 重新定义 btrfs 文件系统大小 6. The Ext4 file system is mainly used on Linux, while the NTFS file system is commonly used on Windows, and the HFS+ file system is suitable for macOS. 0 SSD drive used was a 250GB Samsung 850 PRO solid-state drive connected both via SATA. 挂载 btrfs 文件系统 6. Btrfs, ZFS, and bcachefs are probably your best bets out of the 19 options considered. To be clear, I am using RAID0 with two SSDs with strip size of 256Kb. I would stick with ext4 for the OS. . Provides good performance for many enterprise work load, and probably some desktop ones too. More uniquely, checksumming can detect errors in the data itself. My current setup is /@ for the rootfs, /@home for home dir, works great. Ext4 and XFS are both great for "I need a filesystem, to store files, on this drive". 1 million iops for ext4, right in line with the spec of the drive times 2,. F2FS vs.
