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?
