Plextor M5M (256GB) mSATA Review
by Kristian Vättö on April 17, 2013 10:20 AM ESTTRIM Performance
Plextor calls their garbage collection "True Speed". They are quite heavily advertising the dirty state performance of their SSDs, although I have to say that I haven't found their SSDs to be anything special in this regard. As we already found out in the performance consistency test, Plextor relies heavily on idle garbage collection: When the drive has no other tasks to complete, it will start cleaning up itself.
For starters, I ran a secure erased M5M through HD Tach to get the baseline performance:
As usual, I followed up by filling the drive with sequential data and then hammered the drive with 4KB random writes (QD=32) across all user-accessible LBAs for 60 minutes. I then ran HD Tach to graph the data:
Performance does get pretty bad, but that was expected given the performance consistency (the lower the random write speed is after torture, the worse the HD Tach graph looks). Next I TRIM'ed all user-accessible LBAs and reran HD Tach to make sure TRIM work as it should:
And it does.

Several large enterprise websites have used this methodology for years for numerous types of testing. This method does not give an accurate portrayal of latency performance. It merely gives one second intervals with thousands of IOPS each, which hides the maximum results in among thousands of other I/O.puppies - Wednesday, April 17, 2013 - link
Spelling mistake in the 3rd line. Should be controlled not controller.Great article btw :D.

Fixed! Thanks for the heads up :-)iwodo - Thursday, April 18, 2013 - link
And we have to wait till Broadwell Chipset before we get SATA Express with ( hopefully ) 16Gbps.abhilashjain30 - Monday, July 29, 2013 - link
You can purchase online from SSD Portal ( http://onlyssd.com/ssd-brand/buy-plextor-ssd )abhilashjain30 - Thursday, September 26, 2013 - link
Recently buy from onlyssd dot com, I got within 2 working days from the order date. Drive working fine....I think in mSATA drive Plextor is better option compare to crucial n more.
