I did find a manufacturer (Seagate) which does offer a SAS variant of what is normally a SATA drive. Is this the specific product you are talking about? The interface itself is perhaps not all that important but drive vendors have traditionally selected that "SCSI" based products are based on high performance hardware with a focus on reliability while "ATA" based products are based on low or medium performance hardware with a focus on cost. There is very little overlap between these distinct product lines. It is rare to find similarity between the specification sheets. It is quite rare to find similar rotation rates or seek times.
