Hmm...
scsi0 : Adaptec AHA274x/284x/294x (EISA/VLB/PCI-Fast SCSI)
5.1.31/3.2.4
<Adaptec AIC-7899 Ultra 160/m SCSI host adapter>
Vendor: QUANTUM Model: ATLAS10K2-TY092L Rev: DA40
Type: Direct-Access ANSI SCSI revision: 03
/dev/sda:
Timing buffered disk reads: 64 MB in 1.59 seconds =40.25 MB/sec
They can do more like 40MB/s, so only two disks could saturate the 80MB/s.
This is in a Dell Precision 620.
