Micron M600 SSD Product Family Overview - SATA, mSATA and M.2
Micron's M600 SSDs in various form factors will soon make their way into systems from OEMs and SI. Today Chris looks at the 256GB and 1TB models.

We rarely get to test SSDs headed to the OEM / system integrator market before the drives are released in notebooks, desktops and other full systems. This isn't the first time we've published an article like this, but it's the first time we managed to secure such a wide range of form factors.


Articles like this are great because they establish a baseline for add-in parts. In the coming months, Micron's new M600 SSD will be available in a range of pre-built system, and as an option on custom-built systems from large OEMs. Some OEMs will advertise the M600 under the product name and others will just list a specific capacity SSD.


If you haven't noticed yet, Crucial has big plans for the company's new 16nm lithography MLC. Samsung, Toshiba and SanDisk moved to triple level cell (TLC) flash technology to bring SSDs to the masses, but Crucial chose to continue shrinking MLC. On the aftermarket side, the MX100 has become a popular SSD for those looking for exceptional value. At the time of writing, the Crucial MX100 512GB costs less than $210 - the 16nm NAND flash used on the drive is what makes those prices possible.


From a technical point of view, the M600 takes one part MX100 and one part M550. The same 16nm flash used on the MX100 was used in the M600, but the M550's Marvel 88SS9189 controller was used. Let's dive in now and take a close look.



Specifications, Pricing and Availability




Micron has the M600 in four form factors: 2.5-inch, mSATA, M.2 2280 and M.2 2260ds (double sided). Four capacity sizes are available in the 2.5" form factor, but the large 1TB size is a 2.5" exclusive. The mSATA and two M.2 variants ship in 128GB, 256GB and 512GB capacities. Micron claims sequential read performance up to 560 MB/s. The claimed sequential write speed is up to 510 MB/s. Random performance tips the scales at 100K read IOPS and 88K write IOPS.


Just as impressive is the endurance ratings for the M600 drives. The ratings vary by the capacity size of the drives. The 128GB model delivers 100 TB, and double for the 256GB model, 200TB. The 512GB model gets a 300 TB rating and the massive 1TB drive is rated at 400 TB.


The M600 series is designed to just sip power. DEVSLP is working on the M600, less than 2mW in that state. The idle average power consumption is less than 100mW with DIPM enabled.




The M600 has several part numbers due to the wide range of form factors and capacity sizes. Since these drives will ship in systems, we don't have any pricing information and the accessory page will depend on what the OEM / SI needs to get the system up and running.




As previously mentioned, the M600 uses Marvell's 88SS9189 controller, the same Crucial used on the M550. The flash is the same 16nm used on the MX100, but the 128GB and 256GB models bring SLC layer functions. Micron calls this Dynamic Write Acceleration. You can read a white paper from Micron that details Dynamic Write Acceleration at this link.
