What file system does QNAP use?
ext4
Based on the ext4 file-system, QNAP NAS supports not only file-based iSCSI LUN but also block-based iSCSI LUN that are operated separately from the file system to fulfill better data protection.
Is ext4 compatible with ext3?
Further, ext4 is backward compatible with ext3 and ext2, allowing these older versions to be mounted with the ext4 driver. Ext4 uses extents (as opposed to the traditional block mapping scheme used by ext2 and ext3), which improves performance when using large files and reduces metadata overhead for large files.
Does Linux use ext3?

Is Btrfs better than Ext4?
Btrfs is growing at a fast rate, but it is still not considered stable. Until now, the ext4 seems to be a much better choice on the desktop system since it is the default file system, and it is faster than the btrfs when transferring files.

Should I use ext4 or btrfs on my Synology NAS?
Most Synology Models allow for use of the BTRFS file system, and many users have to choose between BTRFS and EXT4 for the filesystem on their Synology.

What is the maximum size of an ext4 file system?
Overall maximum ext4 file system size is 1 EB (exabyte). 1 EB = 1024 PB (petabyte). 1 PB = 1024 TB (terabyte). Directory can contain a maximum of 64,000 subdirectories (as opposed to 32,000 in ext3) You can also mount an existing ext3 fs as ext4 fs (without having to upgrade it).

It was initially included in Linux Kernel version 2.6.19, aiming to extend storage limits and improve performance.
