I'm starting to doubt the advice given above: "To prevent the SSD performance from degrading again in the future you can adjust your power settings, to make sure that the SSD stays powered on when your computer goes into sleep mode." I've changed the power setting to never let the SSD power down. Yet every time the machine sleeps, I see that the "power on count" in CrystalDiskInfo increments by one.

My speed ratings were initially dismal, but I discovered that Lenovo had artifically capped the disk access speeds. After reflashing my BIOS (on an X61 tablet -- here), I am now up to SATA II speeds (about 260 MB/s). Now I've set my drive never to power off, supposedly even when the computer is asleep. How can I confirm that garbage collection is taking place during sleep? Is there some field in one of the SSD info utilities (e.g. CrystalDiskInfo) that I can monitor to confirm that garbage collection is taking place? Do I have to run the machine for 6-8 hours booted up into the BIOS, as suggested above, or can I just let it sleep for 6-8 hours to achieve the same result? Also, I found that Win7's defragment utility was still scheduled to run by default after a clean Win7-64 system install on the SSD. I thought Win7 was suppposed to sense that the drive is a SSD and disable defrag? I've subsequently disabled the scheduled defrag. Is that the right thing to do, or will Win7 sense the SSD when the scheduled defrag is triggered and do something else that is beneficial to the SSD, like this TRIM stuff discussed above?
