I'd be more shocked if this weren't also true of nearly all SCSI HW RAID adapters of this era. If you had ordered an HP DL380 server you'd get about the same performance. BTW - I don't think there's anything reasonable about 50-55 MB/s from 6 disks, I'd put the minimum for this era machine at 5 x 30 = 150MB/s.
He was quoting for 6 disk RAID 10 - I'm thinking 3 x 30MB/s = 90MB/s is probably more correct? Having aid that, your point is still completely correct - the performance @55MB/s is poor (e.g. my *ata* system with 2 disk RAID0 does reads @110MB/s).
