Practically speaking, the USB 2.0 bus tops out around 50MB/s. However, most USB 2.0 flash drives don't come anywhere close to that. If you're talking about external hard drives or SSDs, then it's another story. As for the Samsung FIT/BAR Plus, peak sequential reads/writes top out around 420/115MB/s and random 4K reads writes can hit 13/24MB/s. For a USB flash drive these numbers are excellent. I've seen many flash drives that have 4K random writes that hover at a pathetic ~10KB/s (0.01MB/s). Using a journaled filesystem (like NTFS or EXT4) will be downright painful on them. That said, I've seen performance degradation on the Samsung drives.
Technically correct but throughput capability of the interface is of limited relevance when discussing performance of specific drives.
