Hello, I'm looking to upgrade the storage in my laptop, its a MacBookPro11,4 15" 2.2ghz. I just realized they run pci m.2 after going on a hunt for a 2.5" ssd . Anyways I've currently got a 250gb one in here and looking for more storage, preferably a 480-512 but I can work with different sizes. If anyone wanted to trade this smaller one for a bigger one + money that'd be great but worst case I am still interested in buying. These are the SSD specs right now, Capacity: 251 GB (251,000,193,024 bytes) Model: APPLE SSD SM0256G Revision: BXW1SA0Q Let me know!
