Plextor M5S 256GB Review
by Kristian Vättö on July 18, 2012 3:00 AM ESTPerformance vs. Transfer Size
All of our Iometer sequential tests happen at a queue depth of 1, which is indicative of a light desktop workload. It isn't too far fetched to see much higher queue depths on the desktop. The performance of these SSDs also greatly varies based on the size of the transfer. For this next test we turn to ATTO and run a sequential write over a 2GB span of LBAs at a queue depth of 4 and varying the size of the transfers.

Read performance is once again equivalent to the M3, regardless of the transfer size. Overall the read performance is excellent, only Crucial m4 and Samsung SSD 830 are faster at some transfer sizes.
Write performance could be better at small transfer sizes. As you can see in the graph, peformance at transfer sizes between 2KB and 64KB is noticeably slower than what Intel 520, Samsung 830 and OCZ Vertex 4 provide.

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.
