Win7/64 getting slower and slower with SSD

I have an Intel X-25m-80. I installed it early February on Win7/64. Things were great -- everything was very fast.

Now, Windows is acting like it is running off plain HDDs. What used to be maybe a couple of seconds from typing in the logon password to having Windows fully waiting is now around 20+ seconds. Opening windows is fast, but not like it used to be.

Reformat? Check settings?

I can confirm defragmentation has never run. Also, find below a disk access util statistics on the drive:

  1. Well it can't be your SSD. Are you sure that during that 20 seconds the HDD LED is frequently on?

    Do you have any HDDs in your system? Did you check them for PIO errors?
  2. Is the whole drive partioned for Windows? Should only used 80-85% for SSD self optimization.

    Any other hard drives for data/media.

    Is TRIM running (a whole other post). Which I could remember the commands to check. I got 'em at home...

    Download the "toolbox utitlity" from Intel.

    Sounds like to me (common problem with SSD) is the "fragmentation"or Zero-write/Erase problem, when there is alot of write/delete/over-writes. :(

    With a TRIM-enabled OS like Windows 7 you don't have to actually leave unpartitioned space to get this benefit. You just have to avoid filling up the partition.
