On my new PC I want to install both Linux and Windows, each on their own rather small partition, and put the big rest of the 1 TB HDD in a further partition (plus swap). Which filesystem should I use? My thoughts:
- NTFS. Linux has write support, but I noticed on my external HDD a huge performance drop when only a few GB (of 500 GB) were left free - suddenly a few hundred MB took half an hour to copy... Any ideas why? Also no file permissions with Linux, although that is not 100% necessary but would be a bonus
- fat32. Too old, won't support that partition size anyway
- ext3. Windows can read for example via ext2ifs, but what about good write support? I'd even consider a small virtual machine with a tiny Linux installation to only provide a NFS share to its host windows (probably qemu, distro recommendation are appreciated)
- ext4. I lack the experience with it...
It looks lke NTFS is the way to go for now (just as it was two years ago), but I'd prefer a less proprietary solution.
