I’m running EndeavourOS and Windows 11. Each OS is on a separate disk, but I have a data disk that is currently NTFS that mount in both OSes. NTFS causes problems for some things in Linux, and I’m worried it’ll bork the drive for windows eventually, so I’m keen to find an alternative. I’ve read about the WinBTRFS driver so wondering if that is a better way to go?
I don’t want to run a server with a share to access this data because it is way to slow for my needs.
NTFS is considered pretty stable on Linux now. It should be safe to use indefinitely.
If you’re worried about the lack of Unix-style permissions and attributes in NTFS, then getting BTRFS or ext4 on Windows may be a good choice. Note that BTRFS is much more complicated than ext4, so ext4 may have better compatibility and lower risk of corruption. I used ext3 on Windows in 2007 and it was very reliable; ext4 today is very similar to ext3 from those days.
The absolute best compatibility would come from using a filesystem natively supported by both operating systems, developed without reverse engineering. That leaves only vfat (aka FAT32) and exfat. Both lack Unix-style permissions and attributes.
