Under both 2.1.7 and 2.2.1, the 53C875 ultra-wide SCSI-III host adapter, made by J Bond Computer Systems (JDC5075), has the same performance as the 53C825, which is just a wide SCSI host adapter, about 18 MBytes/sec. The disk drive I used are Seagate BARRACUDA 9 (ST19171W) , which seagate claims that can go 40 MBytes in sychronous-transfer mode.

Has someone experimented the throughput of 53C875 ultra-wide SCSI-III host adapter with any wide or ultra-wide drives?
