I don't think this is quite fair on the price/GB chart; I'm not entirely familiar with how the manufacturers configure the drive and how much space you actually have to use but... Firstly is minor rounding errors, for example OCZ Vertex 4 115/128=89.8, which IMO should be 90c. I don't know if you counted cents or what though. Secondly the chart treats 120GB ssds as though they are 120GB, and AFAIK they are 128GB but are called 120GB as a manner of subtracting out a bit to make a round number and to compensate for space lost with TRIM. IMO it is unfair to calculate the values like this, it should be 128GB for all 128GB drive, 96 for the Kingston HyperX 3K and 64 (as it is) for all 64GB drives. So the Samsung 840 should actually be 86c. Also the Kingston HyperX 3K is clearly wrong, I think the author made the mistake of doing GB/Price on this one. It should really be 100/96=1.04c, or 100/90=1.11.
