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?

Well, both are premium disks for enterprise use, both dual ported, both high end, both serial scsi protocol (so same programming methodologies).

In a nutshell, the market moved from FC to SAS at the high-end. Reason is that the low-cost SATA drives are using mostly same chipsets so low-cost SATA drives are driving costs down for SAS.

Forget trying to "convert" one to the other.  This can be done, but it costs much more then the cost of a disk to do so, and conversion only makes sense for a large number of drives as it takes quite a bit of horsepower and electronics to do so.

FC is more expensive because they have always been more expensive, due to economy of scale.   FC DOES have some engineering benefits due to switching, but inside an enclosure there is no reason you need to use FC other then it may be the only game in town.

If your enclosures are designed for FC, and you can't find FC disks at the right price, and don't want to risk going to "used" drives, then you'll simply have to change to another type of subsystem.    FC & SAS aren't interchangeable.
