SSD Much slower than before

I've had a Kingston HyperX 120gb SSD for 2 years now. It seems like it's much slower than it used to be, so I recently ran the ATTO benchmark and I'm only getting 183 MB/s Read and 124 MB/s Write. A review of the device I found had it getting 555 Read/527 Write.

Any ideas on the reason for my huge performance discrepancy? BIOS/mobo issues? Drive dying?(hopefully not)

Thanks in advance!

    How full is the hard drive?

    Older drives required at least 25% of the drive to be free to perform garbage cleanup properly including TRIM.
  2. I have an almost 18 month old Kingston HyperX 3K 128GB as my boot. Been on basically 24/7.
    This is the results from that same benchmark test (just ran it). It appears to still be at pretty much benchmark speeds.


    How full is your drive?

    I currently have 31.1 GB free, out of 111 capacity, which is 28%. Kinda close to the 25% mark. Think I should free up some room? (Also side note, don't think it makes a difference, but I have just the HyperX, not the HyperX 3K)
  4. What is your motherboard model?
  5. Is it verified you are plugged into a SATA III slot?
  6. I have an ASUS P7P55D-E motherboard, and yes, it is plugged into the SATA III slot.

    I would try cleaning up some space on the drive and verifying that TRIM is working properly. Please see the guide below...

  8. Update:

    I just got a new motherboard/cpu (ASUS Z87-A & i5-4670K) and now my read/writes for that drive are back up to where they should be! Thanks for all your answers. I guess my old motherboard's SATA III port was strangling my SSD for some reason.
