That's pretty slow. Comparing to traditional EIDE disks, that's around UDMA2 speeds (a UDMA2 disk on a Dell P3-800 gives 20MB/sec). My USB2 enclosures are faster than that (30MB/sec on a Shuttle AMD-2500).
Timing buffered disk reads: 146 MB in 3.02 seconds = 48.35 MB/sec
That's closer to UDMA5 speeds (approx 55MB/sec on both machines).
All in all, not very impressive!
