  • Since we received the Samsung 850 EVO 500GB model, we don’t really get a huge benefit from having TurboWrite. TurboWrite performance on the Samsung 850 EVO 500GB is 520MB/s sequential writes and 90,000 IOPS 4K random writes, however, the after TurboWrite performance is still a respectable 500MB/s sequential writes and 80,000 IOPS 4K random writes.

    I was thinking of either selling the new 850 evo that comes in and putting that money towards another evga sc gtx 980 for an sli configuration ORRR use the second samsung 850 evo 500gb for all the random writing/temp files/video recording and editing... kind of like a heavy use ssd with the other for more of a longevity purpose. Figure if the second ones going to fry I might as well get some heavy use out it while preserving the 1 with my OS and files.

  • After reading some reviews about samsung ssd's I see that their quality is questionable. I'm not going to raid0 it when it gets here but now I'm wondering if I should even keep it... I have 2 3tb hdds for storage and now the 1 samsung 850 evo 500gb ssd for os and games/apps

    Above we have both the Samsung 850 EVO 500GB and the Samsung 840 EVO 250GB running 128K random writes with zero pre-conditioning. On the Samsung 850 EVO 500GB, there’s very little loss of performance until the drive gets filled with data and there’s very little difference between TurboWrite and after TurboWrite performance. On the older and more importantly lower capacity Samsung 840 EVO however, there’s a significant drop in performance after just a couple seconds of high performance writes which signifies that the drive is in after TurboWrite mode. Similarly, this is what I expect from the Samsung 850 EVO 120GB and 250GB drives as well although I didn’t get a chance to actually test either of those drives.

  • On the Samsung 850 EVO 500GB, Samsung includes 512MB of LPDDR2, which is about 1MB of DRAM/1GB of total NAND capacity. Similarly, the 120GB model gets 128MB and 1TB gets 1024MB for that 1:1 DRAM to NAND ratio as well. The 250GB Samsung 850 EVO however, gets 512MB of LPDDR2, which represents 2MB of DRAM/1GB total NAND capacity.

For our review, we received the Samsung 850 EVO 500GB. We expect this capacity to be the top seller in the Samsung 850 EVO lineup as it offers an adequate amount of storage space for most users, it has the 150TB warranty, and it’ll be coming in at a significantly more affordable pricepoint than the 1TB capacity drive.
