ADATA SP900 256GB SATA M.2 2280 SSD – Review

Posted October 16, 2014 by Sandy Bruce in Storage, HDs & SSDs


Release Date: Currently Available
Price at time of Review: $140


Smaller size, easy to install, consistent speeds, price compared to other M.2 drives


Price compared to Standard SSDs, Speed largely unchanged from Standard SSD
Overall there are just enough benefits to justify the $20 average premium for using M.2 instead of a standard SSD. We are just now stepping into the M.2 era and the SP900 is a good stepping stone.

So after all of the eager anticipation for M.2 to hit the market, the dawn of NGFF is finally upon us, and many of us yawned. This is not ADATA’s fault, mind you: This is what happens when there has been hype built up for over a year, promising to change the face of small form factor storage. Blistering speeds, low power draw, larger capacity in really small form factors and a direct connection to the PCIe bus. Some of this did come true, but other features have been reserved for only those that can afford it. I am sure many missed the fine print explaining that not all M.2 drives were created equal. Instead some will rely on a SATA3 interface for speeds that match what you currently have with your other top-of-the-line SSDs and others will only knock your socks off after you lay your wallet on the counter to give them all of the money. Relax folks, all is not lost, as it comes down to making sure you as a buyer know what you are buying and why.

M.2 will be here to stay. It is an interface that has a lot of attention and a lot riding on its success. The varying levels of speed associated with M.2 may create a bit of confusion at first: SATA3 6GB/s is on the lower side of the M.2 equation, followed by PCIe2 x2, select drives will use PCI2 x4 and some board manufacturers are claiming to have PCI3 X4 support. The SP900 is a drive to fill the void on your new shiny Z97 and X99 board that isn’t substantially faster than most SSD’s, but should allow for slightly faster boot times, save you some drive bay space and eliminate the need for SATA and Power cables. The SP900 can really come in handy in mITX projects where space is at a premium.

Overall there are just enough benefits to justify the $20 average premium for using M.2 instead of a standard SSD. We are just now stepping into the M.2 era and the SP900 is a good stepping stone into M.2. With prices for NANDs dropping faster than ever before, expect the current $140 MSRP to not hold for very long. The closer M.2 performance and price gets to that of a standard SSD, the easier the choice to go with M.2 will be. The ADATA Premier Pro SATA3 SP900 M.2 SSD is a solid drive that earns PureOverclocks Great Hardware Award.





    I’m confused by the bits to bytes conversion this site is using for SATA speeds. Why would 6 gigabits/sec equate to 600 megabytes/sec? One byte is eight bits, therefore 6 Gb/S would be approximately 750 MB/s. Are you trying to get closer to real-world speeds due to overhead? If that’s the case, the overhead shouldn’t increase for higher speeds, so one wouldn’t expect the 10:1 ratio you use for faster speeds bits to bytes. Is there some new piece of tech info I’m missing?


      You are overthinking it a bit. It’s simply generally accepted in the PC industry that for simplicity’s sake we use a 10:1 ratio. We all know that binary doesn’t equate that way, but it makes it less confusing for the lay person and makes for quicker math that is roughly equivalent.
