16G is overkill..
I just posted it as it was the first that i saw from amazon, was just an example. He isnt getting it from the US regardless, so was just for pure purpose of not buying DIMMs but SODIMMS.
Crucial m4 128GB mSATA
The recently released model (M500) has a reliability feature that's not on other consumer drives (as far as I know). The real-world impact is anyone's guess.
The M500 seems better on paper, but there are 3 things that i dont like
1) Its too new, its firmware might take some time to mature. The M4 has almost 3 years on the market so the firmware is stable and probably wont encounter much issues.
2) The M500 has a temp throttling design, if it passes 65C, it underperforms, i never seen on the reviews that it has been reched... but maybe on mini itx with little ventilation and being close to the cpu might be reached, assumptions on my part, might be none issue in reality.
3) The M500 best performers are on the 480/960gb version, by design they made it so the higher capacity has better sequential writes, the 240/120 are kidna crippled by design. While the M4 was deign to get the full speed on 128gb version (even its faster in some benches than my 256gb). Probably wont be detectable by the end user, all ssds in my experience are equally responsive, on a blind test i couldn't pick either.
So in all i would still go with M4 over M500 for msata unless going with the 480gb version.
