SSD has over 1000ms response times!

In the Windows Resource Monitor, my solid state drive typically has response times of over 1,000ms in several files. My read/write benchmarks are still fine, a little slower than when I first got it, but nothing major. It's just that the disk length queue (which is also typically idles at 0.2 - 0.4 and peaks from 5 to 25 during minor disk activity, like browsing this forum) and my response times seem TERRIBLE. I get the feeling this is probably highly unusual and would explain my slowing boot times and unresponsive computer. Is my SSD failing?

Edit: TRIM is active in Windows and is supported by the drive.

More about 1000ms response times
  1. I would examine the SMART report for the drive.

    You could use smartctl from smartmontools for this purpose.

    Here is the Windows package:
