Only for the per-char benchmarks. That is normal. >3. Where is the 8MB/Sec reported in this thread? I saw 1.5 or so. The drive is a Barracouda and is not capable of sending/receiving 8 MB/sec. I didn't calculate, but I think it should max out somewhere between 5.5 MB/sec and 6.5 MB/sec (in theory). A SGI indy R 4600 PC drives this HD at 5.3 MB/sec (block read). I have about 500 results from bonnie.
