Specifications, Pricing and Availability




Crucial gives us just enough data on their specifications sheet to allow us to do this page. The mSATA m4 is available in three capacity sizes, 64GB, 128GB and the unit we're looking at today, 256GB.


The performance changes from one capacity size to the other. The read speed on all four drives is 500MB/s, but the write speed and IOPS change throughout the range. The 256GB drive has a sequential write speed of 260MB/s with 45K read IOPS and 50K write IOPS, all at 4KB aligned random. The smallest drive in the lineup, 64GB has a sequential write speed of 95MB/s, read IOPS of 45K and write IOPS of just 20K. The 128GB capacity size resides in the middle with 175MB/s write speed, 45K read IOPS and 35K write IOPS.


Crucial has already released these parts on the market and we managed to find them at Amazon and Crucial's own web site. On Crucial's site they list at $71.99 (64GB), $117.99 (128GB) and $225.99 (256GB). The prices on Amazon were a little higher than Crucial's website, but we did find something odd on Amazon, a 32GB model.


When it comes to accessories and add-ons there really isn't much you can give away with an mSATA drive. Crucial does include a three year warranty.
