Plextor M5S 256GB Review
by Kristian Vättö on July 18, 2012 3:00 AM ESTAS-SSD Incompressible Sequential Performance
The AS-SSD sequential benchmark uses incompressible data for all of its transfers. The result is a pretty big reduction in sequential write speed on SandForce based controllers, while other drives continue to work at roughly the same speed as with compressible data.
Incompressible sequential read performance is in fact slightly (2-3%) faster than in M3 and M3 Pro.
Incompressible sequential write speed falls right between the M3 and M3 Pro. Plextor is claiming up to 390MB/s sequential write on the M5S and it does get very close to that with incompressible data.

I finally picked up my M3 about 2 weeks ago now, just in time for the M5s to be released. No regrets here. I am using this in my W520 notebook, and the machine loves it. It is disappointing to see how much performance the new drive lost just to make it more marketable.inplainview - Saturday, July 28, 2012 - link
There is no such thing as a pre-order. You either order or you don't order...alan1476 - Saturday, September 1, 2012 - link
Newegg reviews are very bias, only the people with drives that 1. They do not know how install, using ACHI Mode) or they are using the wrong posts, or they actually have a bad drive, you never know with those reviews. Everyone that buys from Newegg is an expert. LOL.
