USB Flash Drive Comparison Part 2 — FAT32 Vs. NTFS
Dampeal writes "Ok, a little while back I ran a somewhat large USB Flash Drive Comparison with 21 drives compared, today I got part two of that comparison. I've taken the 8gig and 4 gig drives, nine in total, and formatted them FAT32, NTFS and ExFAT and ran all of the tests over again for a comparison of how the file systems work on the drives." Good news — after some exhaustively graphed testing scenarios, the author comes to a nice conclusion for lazy people, writing "[I]n my opinion the all around best choice is FAT32, or the default for most all USB drives out there today, it seems to give us the best average performance overall."
FAT32 is great, unless you want to exceed the 4gb filesize limit. In which case you will need an alternative.
The days of the digital watch are numbered.
The question about filesystems has come up a few times over on the Dell Mini forums. Basically the question is which is better to use on machines with SSDs? If you're not dealing with >4GB files, several people have suggested that you're better off formatting the drive as FAT32. I'll need to take a better look at this article when I get a chance, but it seems to be suggesting the same thing.
FAT32 is fine for a USB stick, but you shouldn't install an OS on it. The problem is that FAT32 has no concept of file ownership. So your operating system will be unable to restrict access to files based on the user, which is one of the building blocks of security on any modern OS. This way, any (malicious) process running on the system can overwrite critical system files to do arbitrary damage.
Even if you run windows XP as adminstrator, not all processes on your system run as administrator so you will still be (slightly) decreasing security by having it on a FAT32 filesystem.
