    Hi, I've had the OWC 115gb(firmware 360A13F0) for a couple of months and noticed it was slowing down especially when booting up and also running other apps.

    I reinstalled 10.7.2 and ran some tests using Black Magic Design Disk Speed Test and AJA. Black Magic has write speeds between 50-65MB/s and read speeds of 90-125mb/second. I remember doing these tests when I purchased the drive and recall they were much higher.

    Here is Xbench for the SSD. (I tried running it on the 500GB hard drive on the laptop but it had an error 5000.) Are these OK numbers?
