    I have attached a profile of my 256 SSD that came with my nMP as well as a 512 module I purchased. The 512 appears to be a 2 lane module. Have I properly interpreted the System Profiler results?

    Have you tried to ran a benchmark like Black Magic? Thinking the 4 lane might be faster no?

    Here's my 512GB SSD. Stupid question, but would the link speed have anything to do with the video cards? I have D700s FWIW.

    The difference is in the Revision of the SSDs. I have a loaded Late 2013 27" iMac with a 512GB PCIe SSD. It has the same revision as your 512GB, UXM2EA1Q. The 256GB that came with your nMP is UXM8JA1Q.

    My best educated guess is that there is a firmware block that keeps some PCIe SSDs from linking at x4.

    EDIT: This would also explain why each SSD from each particular model (MacBook Air, rMBP, iMac, nMP) all have different part numbers even if the capacity is the same.

    Anand clearly indicated in his nMP review that the nMP comes with a x4 SSD unlike the MacBooks...

    FWIW, my stock 1TB SSD in the nMP is x4

    The Late 2013 rMBP 15" has a x4 1TB PCIe SSD.....I've tested one from a customer.

    Right... In re-reading his statement, it implies the nMP only comes with x4 whereas I suppose the MacBooks were offered with both x2 or x4 SSDs.
