Could you tell me what is the difference between FC and SAS disks.
Recently we bought 600GB 6GB/s SAS disks 15k, and now we need to buy FC and as I see from the offer from different company FC are two times more expencive than SAS disks, even though I am buying 450 GB FC disks.
Why 450GB disks are so expensive? What they provide more than SAS 6GB/s SAS disks 15k. Their performance is better or anything else?
