Is my SSD working properly?

Hey guys. I recently purchased a Kingston HyperX 120GB 2.5" SATA 3.0 (6Gb/s) READ 525MB/s WRITE 480MB/S


Running ATTO Disk Benchmark I get the following results:



They seem to great results (I'm new to SSDS and I don't know much about them)

However, I get the following results using Crystal DiskMark 3.0.1

  1. yes, it's very fine no need to be worry.:)
  2. Write seems a little low to me.

    A bigger problem you have is posting massive images. :)
  3. it's ok not low.
  4. Absolute nonsense.

    TweakTown have a their ATTO benchmark pretty much at the advertised speeds using SATA 3.

    How can you consider this performance to be "OK"?

    Scatmango you are using SATA 3 right? Make sure you have the latest SATA controller drivers installed.
  5. really? now what are the real writes.
  6. The OP is concerned about the difference in numbers between ATTO and crystal mark.

    If you do a comparison with what Tweaktown manage with CrystalDiskMark, the same benchmark the OP is using, you'll see that the OP has less write performance than Tweaktown have reported.

    In any case Scatmango, whilst the write performance is less than Tweaktown have reported, your ATTO and Crystal benchmark mirror their findings. You don't need to be concerned about the performance difference between the two. It's probably just the difference between their hardware and yours.
  7. ^5 +1 what Rusting in Peace said.

    Actual solid state drive performance may differ from published specifications and benchmarks for a variety of technical reasons.
  8. Good grief people, anyone testing an OS drive is not going to get the same performance that you see in these hardware reviews. The drives in these "tests" are benchmarked as a bare drives under the best possible conditions. Once you load an OS on the drive, or start filling it with data, some of those numbers start falling off considerably.

    You're completely right. I'm just using it as reference comparison though. I think it's more useful that just providing a yes or no answer.
