Slow Samsung 840 SSD

My motherBoard is sata 2 compatible, the SSD is sata 3, so I am losing 3 gbits/s there.
But theoretically I should be getting 3 gbit/s on the tests, correct?

*FYI, the drive is actually alot faster than my old drive. I just meant slow in
comparison to the offered 6 gbit/s it sports

  1. I was under the impression 200 mb/s was sata I speeds?

    SATA 1 (1.5Gb/s) speeds are from 1MB/s to 150MB/s.
    SATA 2 (3Gb/s) speeds are from 151MB/s to 300MB/s.
    SATA 3 (6Gb/s) speeds are from 301MB/s to 600MB/s.
  3. You never achieve the theoretical speeds of the SATA ports/standards. Just keep that in mind. Also, you are comparing apples to oranges here with gigaBITS vs. megaBYTES.

    Looks like you are actually doing okay. Have fun!
  4. Your numbers are fine!
