And I believe they cannot hold too much space... all I can see are smaller 15K RPM drives... who is crazy enough to pay US$ 160 for a single 147 GB SCSI drive, while you can spend US$ 130 and get one 7200 RPM drive with 1.5 TB?
Actually, they are surprisingly sizeable, if you are willing to pay the premium.
See this data sheet:http://www.seagate.com/docs/pdf/marketing/po_cheetah_15k.7.pdf
These are 15k drives available up to 600GB, though I would expect costs for the 600 gig model to be upwards of $500. Each.
If you're willing to pay that, you should be willing to pay for a SAS controller card as well.
