This is probably a "memory and storage" topic but since it pertains to this drive - what's w/ the rated write speed being significantly lower on the 128GB versions of this drive? On the box, and on the Samsung site, it shows "sequential write speed" for the 128GB version of 390MB/s. Comparing to the 256GB version showing 520MB/s.
It's still faster than the non-Pro 840 (130MB/s) and a little faster than the 830 (320MB/s) when looking at the 128GB versions.
Probably a safe bet that it's not something a human would notice in daily usage, but it's a little disappointing. Figured I was getting one of the fastest (affordable) drives possible for my new build, now I'm thinking I should have just gone with a cheaper 830.
