THG goes into the gritty details of Serial Attached SCSI (SAS), including background on the technology, available hard drives, & available controllers. Good bit of info on the technology that is sure to replace conventional SCSI here in the near future.

"Although the current SAS specification defines a 300 MB/s bandwidth per port, which is less than UltraSCSI's 320 MB/s, exchanging the sharedbus by point-to-point connections between devices is a huge advantage. The second important ingredient for SAS is the SCSI protocol, which is popular and powerful."
