Power Consumption

Samsung has always been pushing hard with power consumption and the 850 Pro is another proof of their efforts. Slumber power is down by a bit compared to the 840 Pro and generally speaking the 850 Pro is one of the most efficient drives. Even load power consumption stays at below 2.5W, which is superb given the performance of the 850 Pro.

    No, it's really "600 MB/s whatever". In reality about 550 MB/s seems to be the maximum. With 300r + 300w full duplex neither read nor write could surpass 300 MB/s.

    why I ask this
    I see a lot op people putting SSDs in RAID0, and I wonder why ... to me, it seems totally pointless
    the system doesn't do only writes or only reads, so what's the point? well, except in the cases where you copy/move some huge files from one matrix to another

    Copying large files, and loading large files. Realistically, you can copy from a new SSD to another at anywhere from 250MBps to 450MBps (including OS/filesystem overhead). That's halved, or worse, copying from an SSD to itself. RAID 0 gives you an approximately linear bandwidth increase. If you don't need a logical or physical separation of data locations, RAID 0 beats a separate drive.

    When I'm backing up my Bethesda games directory, I wish I had more speed, as it could be done faster in a RAID. However, I only do that one or two times per month (all my saves for all my games are on automatic backup).

    For typical light random IO, it very much is pointless.

    Easy, say you have 2 sata 2.0 SSD but want sata 3.0 speeds.

    Typo?

    "I bet many of you would have liked to see the 850 Pro move to the PCIe interface but I understand Samsung's decision to hold on with PCIe for a little while longer."

    I think the second PCIe should be SATA.

    of the "on" could be a "off'

    How many P/E cycles does the NAND on this drive support, by SMART data?
  • Kristian Vättö - Tuesday, July 1, 2014 - link

    I will test that as soon as I get back from Korea, as well as send you the Extreme Pro data. Sorry for not replying to your email earlier, I kind of lost focus on everything else when I started working on this review :)

    No problem, thanks!

    You should actually put up a little pipeline article with all of this data, because it would be interesting to me, and I am sure lots of other users as well.
