zfs vs ext4 performance

On a simple setup, like ZFS or ext4 on a system with a single hard-disk or SSD, ext4 will be faster for most operations. But if you turn on compression on ZFS, it may be faster than ext4 with highly compressible data (for example text files, code projects, etc.). ... Writes, however, will still be faster on ext4.

Is ZFS faster than ext4?

That said, ZFS is doing more, so depending on the workload ext4 will be faster, especially if you have not tuned ZFS. These differences on a desktop will probably not be visible to you, especially if you already have a fast disk.

Should I use ZFS or ext4?

ZFS may be the best-known enterprise-grade transactional file system to use storage pools to manage physical storage space. ZFS supports advanced file systems and can manage data long term whereas ext4 cannot. ...

Is ZFS faster than XFS?

Resource utilization and performance

If you are using ZFS with all the default values set, then it will use more resources than XFS and perform slightly worse in terms of I/O but, with modern hardware and faster CPUs, this difference is negligible.

Is ZFS better?

The main reason why people advise ZFS is the fact that ZFS offers better protection against data corruption as compared to other file systems. ... The fact that ZFS is better at protecting your data against corruption isn't that important for most home NAS builders because the risks ZFS protect against are very small.

Is ZFS the best file system?

ZFS is the best file system for data you care about, hands down. For ZFS snapshots, you should check out the auto snapshot script. By default you can take a snapshot every 15 minutes and up to monthly snapshots.

How much RAM does ZFS need?

With ZFS, it's 1 GB per TB of actual disk (since you lose some to parity). See this post about how ZFS works for details. For example, if you have 16 TB in physical disks, you need 16 GB of RAM. Depending on usage requirements, you need 8 GB minimum for ZFS.

Is ZFS better than Btrfs?

The reality is that, today, ZFS is way better than btrfs in a number of areas, in very concrete ways that make using ZFS a joy and make using btrfs a pain, and make ZFS the only choice for many workloads.

Is XFS better than Btrfs?

Advantages of Btrfs over XFS

The Btrfs filesystem is a modern Copy-on-Write (CoW) filesystem designed for high-capacity and high-performance storage servers. XFS is also a high-performance 64-bit journaling filesystem that is also capable of parallel I/O operations.

Is ZFS better for SSD?

ZFS works great with SSDs. If you're planning to do things involving heavy I/O workloads, consider a much smaller recordsize than the default 128K. ... In my experience with samsung ssd's, creating the zpool with ashift=13 instead of ashift=12 gives better results.

Is XFS still used?

It can now handle volumes up to 32 Tbytes and file sizes up to 2 Tbytes. It is still used on many flash-based storage systems along with the FAT file system. It lacks the journal system found in ext3 and ext4.

How reliable is XFS?

XFS is very reliable. In fact, it might be more reliable than ext4, although that is debatable. XFS is also the primary file system supported by Redhat.

Does XFS support compression?

There are 3 filesystems that can do transparent compression: NTFS, ZFS, btrfs. ... XFS could really benefit from compression support.
