Can I upgrade my 2009 SSD HD to the 2010 model?

Question

I have an April 2009 MBP with the 120 GB SSD. I have heard that this is the same SSD that went in the Macbook Airs, and has slower read speeds (48 MB/s) than the current SSDs on the new MBPs.
Question:
Can I take my MBP to my Apple store and have them switch out the old SSD for the new one? how much would it cost? how much would it cost to upgrade to a new 256 GB?
or can I order the drive from Apple and install it myself?

Answer 1

You can't order a drive from Apple and install it yourself, but if you could, it would undoubtedly cost more than ordering the same drive from any other vendor. So the thing to do is order the drive you want from an online vendor who offers it at a price you can stand.
There's no assurance that any two MacBook Pros of the same model will contain the same SSD. Apple buys SSDs and hard drives from several different manufacturers, undoubtedly depending on specs, pricing, current availability, and other factors known only to Apple. So although it's quite possible that some MBPs contain faster SSDs and others contain slower ones, there's no way the buyer of a MBP can specify what SSD make or model s/he wants in her/his machine — except by buying one from a third party and self-installing it.
EDIT: I forgot to mention that yes, you can have Apple install a different SSD in your MBP if you like, paying for the labor as well as the unit (at the Apple price). But you still won't be able to specify what drive model you want — only the capacity. And you won't know what you've gotten until you've paid for it.
