Final Thoughts


Samsung's SSD's are completely in-house products. Samsung flash, Samsung controller, and Samsung DRAM. Not needing any third party components gives Samsung an inherent advantage over the competition. In addition, Samsung currently enjoys a technological advantage over the competition and it shows.

The 500GB 850 EVO M.2 does not trade size for speed. A smaller PCB and less parallelism have virtually zero negative effect on the 500GB 850 EVO M.2's performance; it's every bit as fast as the 2.5" version, maybe even a bit faster. Overall, and RAPID aside, we have to say the 500GB 850 EVO M.2 SATA III SSD is the fastest SATA-based SSD we've ever tested. Samsung's TurboWrite technology and 3D flash combine to deliver performance that is a cut above. A TBW rating of 150TB, lowest in class power consumption, a five-year warranty and low cost of ownership are all just icing on the cake.

Because we perform most of our evaluations with the test subject running as our boot volume, we can comment on how the drive performed with our OS. The 850 EVO M.2 boots faster than any SATA based SSD we've used. Once inside Windows, the drive handles like a dream. It performs so well, there is a noticeable difference between it and most other SSD's. To be perfectly honest, we actually prefer the 500GB 850 EVO M.2 to the 850 Pro. Samsung's TurboWrite elevates TLC flash like nothing we've ever experienced and we would like nothing more than to see this technology implemented on the 850 Pro.

The M.2 form factor is more versatile than a 2.5" SSD and we find it the most appealing of all form factors. There is something to be said for a drive that just disappears into your motherboard. No data cable, no power cable, just a tiny 22mm x 80mm PCB. Samsung's 850 EVO is the best performing SATA-based SSD on the market, and the M.2 version is the best 850 EVO.


  • Best performing SATA SSD to date
  • Lowest power consumption
  • RAPID Mode


  • Low performance during an extended heavy-duty workload

Samsung's 500GB 850 EVO M.2 is a must have. We award it our highest rating and highly recommend it for your next SATA SSD purchase.
