WD My Passport
4 TB
As far as I'm concerned, I'm using it in a Linux environment in which it is formatted as EXT4. I would say that any USB3 compatible drive should work on the box, provided the file system is compatible (so probably FAT32 in theory, but more probably NTFS and maybe HPFS). As for Time Machine, I can't say for sure. It came formatted as NTFS, is not loud at all and does the job well.
