Yes, they are a bit pricey compared to 7.2K but they are fast. Size vs. price becomes the issue though and you may just want to go with some simple 7.2K SATA drives.<BR>

Both are 3Gbps but sas has faster rpm and higher heat tolerance.<BR>
But sata is easier to replace before failure due to cost. Replace every 4 years with a 5 year warranty drive and send it to a desktop.<BR>
