I've got a 2TB external HD on which I save valuable data. so far I'm using NTFS as my file system, but I find it quite slow because I've got lots of files there. (700GB of videos, 20GB of music, etc.)
I want to encrypt some of the files (personal) and not the whole partition, and I would like the partition to run smoothly and not as laggy as now.
I read about JFS and EXT4 and EXT3 but each of them has got pros and cons. Can someone explain to me which one is the best for my needs?
