About the M.2 and SP550…
Unlike the mSATA SSDs, I really like the concept behind the M.2 form factor. It enables manufacturers to put in higher capacity and number of NAND. The interface allows a system to take full advantage of current generation SSDs, unlike the limited SATA format that runs up to 6Gb/s.
The ADATA SP550 240GB M.2 drive that I have for review is in M.2 2280 form factor. It runs on SATA 6Gbps interface. So these are M.2 drives are entry-level M.2. Many NUCs, ultrabooks and desktop units have at least one M.2 interface. So this would be a low-cost upgrade from the traditional mechanical drive that comes in typical low-to-mid-end systems. Some devices like the ultrabooks and notebooks use them as well. The last time I saw in a pre-built unit was in the Lenovo Y700.
What would be interesting to see is what performs better- an SSD of a similar class like maybe a Kingston UV400 or a low-cost M.2 alternative. Would you choose to free the SATA port (or use it as secondary storage), or the M.2 port as a primary drive?
Packaging and Closer Look
As you would assume judging by the form factor of the storage drive, the ADATA SP550 M.2 drive comes in a small box enough to pop one in your pocket. I would have liked to see the drive in an anti-static wrap.
You can download the Acronis migration utility and SSD Toolbox. ADATA insists on registration the drive for warranty which shouldn’t be a hard step to take. The internal pack is nothing out of the ordinary. It would be a good idea to have a bit better packing to avoid any transit damage.
The ADATA SP550 M.2 is bare PCB with Silicon Motion SM2256K controller, a four-channel with a NANYA NTCB128M16FP-DI and four ADATA labeled TLC chips. Just like traditional HDDs and SSDs, as long as M.2 drives do not exceed operational temperature, it’s all good.

ADATA mentions interface as “SATA 6Gbps” since its Silicon Motion controller typically in SATA SSDs. There are two variants, with the other one in a typical 2.5” SATA form factor. While ADATA mentioned the performance numbers keep in mind that it varies between systems and capacity.
