Retina MacBook Pro SSD
Keep in mind that although the interface is electrically SATA, it is not physically SATA or mSATA or any other standardized interface - this is entirely Apple’s own creation. I suspect we’ll see 3rd party vendors produce SSD upgrades in the future, but unlike previous Apple SSDs, performance won’t be a reason to want to upgrade. Samsung’s PM830 is quite honestly the best behaved SSD controller I have used under OS X, it is no surprise that Apple chose it.
Apple is now advertising its flash storage as being faster than hard drives, whereas in the past it merely stressed that SSDs were more reliable.
