The Comparison of Btrfs vs Ext4 Filesystems

The Btrfs filesystem has a built-in logical volume manager (LVM) that is used to add multiple storage devices or partitions to a single Btrfs filesystem. A single Btrfs filesystem can span over multiple disks and partitions. The Ext4 filesystem does not support multiple devices.

Is Btrfs better than ext4?

For pure data storage, however, the btrfs is the winner over the ext4, but time still will tell. Till the moment, the ext4 seems to be a better choice on the desktop system since it is presented as a default file system, as well as it is faster than the btrfs when transferring files.

Is Btrfs slower than ext4?

Some performance observations on Btrfs vs Ext4 random-read/write I/O. I mean it's not really surprising that BTRFS is slower than EXT since it checks the checksums of blocks it reads to validate that the data isn't corrupted. ... It's not just slow because of the checksums, it's also because of CoW.

Is Btrfs better?

Btrfs exists because the developers wanted to expand the functionality of a file system to include additional functionality such as pooling, snapshots, and checksums. ... Considering that btrfs will be able to span over multiple hard drives, it's a good thing that it supports 16 times more drive space than ext4.

What are the advantages of Btrfs?

The two biggest advantages for me are easy volume management and snapshots. With volume management, I can put one huge btrfs on my drive (or even on multiple drives), then organize them with subvolumes. This means I will not run out of space in root while still having many GB free in /home, or vice versa.

Which is the fastest file system?

The thing is that there's no such thing as the fastest file system for all uses. For example, a defragmented FAT32 partition is faster than NTFS for simple reads and writes. However, NTFS is a lot faster than FAT32 in cases where there are a lot of files present in the directories being read.

Should I use Btrfs or XFS?

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 Btrfs slower?

btrfs is always going to be slow in write heavy workloads due to being a COW filesystem. If you need the extra speed in that specific workload why not just disable the COW features using chattrib.

Is Btrfs faster?

Btrfs has many good features. ... However, for pure data storage, Btrfs is the winner over ext4, but time will tell. For now, ext4 seems to be the better choice on a desktop system since it is already present as a default file system, and it is slightly faster than Btrfs when transferring files.

Is Btrfs stable 2021?

To sum it up: in terms of development Btrfs is still alive. In terms of adoption in distributions/software some are offering it as an option, only few take it as standard file system, and there is not much commercial software out there which does require Btrfs.

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.

Can Windows read Btrfs?

Btrfs for Windows by Paragon Software is a driver that allows you to read Btrfs-formatted files on a Windows computer. Btrfs is a copy-on-write file system designed at Oracle for use in a Linux environment. Just plug in Btrfs storage to your PC and get a read access to the content with Btrfs for Windows driver.

Who uses Btrfs?

The following companies use Btrfs in production: Facebook (testing in production as of 2014/04, deployed on millions of servers as of 2018/10) Jolla (smartphone) Lavu (iPad point of sale solution.
