SATA II and Jumpers

I always knew there were jumpers on some SATA drives, but I never took the time to see what they did. Recently I had a problem with a friends computer where we couldn’t get the drive to recognize and the reason was that there was no jumper setting it to a SATA I. I was setting up an RMA for a Seagate today and noticed that all my Seagate SATA II drives had jumpers on set to SATA I. According to h2benchw the 500 is running faster in some cases than the Raptor :(.

Western Digital Raptor 150
h2benchw -english -c 2 0
sequential read rate medium (w/out delay): 81.4 MByte/s
sequential transfer rate w/ read-ahead (delay: 0.84 ms): 102.9 MByte/s
Repetitive sequential read ("core test"): 115.2 MByte/s

Seagate 500
h2benchw -english -c 2 2
sequential read rate medium (w/out delay): 72.2 MByte/s
sequential transfer rate w/ read-ahead (delay: 0.95 ms): 134.2 MByte/s
Repetitive sequential read ("core test"): 129.1 MByte/s
