Anyone know if SAS drives will work in a MacBook Pro?

I'm buying a stock MacBook Pro at the Apple Store with the 5400 RPM drive, but I'd like to upgrade to a 15K RPM SAS 2.5" drive. Wasn't sure if Apple's HDD backplane supports SAS or not.

No, it doesn't support SAS, and even if it did, you don't want to put one of those 15k drives in the MBP enclosure. It would probably die from heat (dissipating ~15W instead of ~2W!) even if the controller did support it.

Doesn't Apple only use SATA 2?

Signature depreciated.

SATA is not SAS: SATA means Serial ATA, SAS means Serial Attached SCSI. You can use SATA drives on an SAS controller, but not the other way around. Also, as mduell pointed out, 15k 2.5" SAS are meant for blade servers and such. I doubt we'll see these kinds of drives in notebooks anytime soon.

Wasn't sure what controller they used. Darn. 
Sure would be awesome, though.

Well, there's a reason for it: these drives simply run too hot.
Although IMHO Apple should include SAS with the Mac Pro and its drive bays: people would be able to put in the latest SAS 15k drives if they want to (and are able to pay for them).

You can get 10K rpm 2.5" SATA drives - but they aren't designed for laptops. They are meant to go into blade servers... so your battery life would suck - and they are very noisy.
