    I have been reading the massive thread on these drives, but not sure I understand everything correctly.

    0A2 drives are much slower (I think there are two versions of this drive)

    0A6 drives are the ones that everyone wants, because they are much faster

    I found one with a part number (pic attached) but I can't figure out if this is the 0A6, or 0A2 drive. Can anyone confirm?

    Also, when did the 0A6 drives start being produced? Looks like last December is when people started posting on here.

    Lastly, is it worth buying a new drive? Or are the USED drives coming out of MacBooks good enough?

    Pretty sure the /Ax is related to the Mac model it's for and doesn't relate to the speed. The original 1TB part for the nMP is MZ-KPU1T0T/0A1. I think the new faster ones are MZ-KPV1T00 or MZ-KPV1T0R, but I could be wrong. The /0A1 part has an RFI shield (some people call it a heat shield) whereas the others do not. I'm not sure there's any difference between the /A2 and /A6 other than for inventory tracking purposes.

    So there is no speed difference between the 0a2 and 0a6 models?

    And from the box pic, there is no way to confirm which revision it is?

    Someone else who has done speed tests across these different models is going to have to chime in here. My understanding, which could be wrong, is that most of the drives in circulation are the same speed, with different model numbers to indicate whether they're for the nMP, rMBP, or iMac, and that the /0Ax at the end of the Samsung part number designates that. I think /0A1 is nMP, /0A2, is rMBP, and /0A6 is iMac. I don't think there are speed differences between these, but some sellers are capitalizing on the interest stirred up by the few instances of a next-generation version (with a completely different part number) that appeared on eBay, which to the best of my knowledge, there hasn't been any recent reappearances of. It's possible that the /0A6's that shipped with the retina iMac are faster, but that should be reflected in the rest of the part number. FWIW, according to the Google, the Apple part number on the box you showed is for an rMBP (these drives typically have Apple part numbers and Samsung part numbers).
