My SSD Hard Disk freezes intermittently.

I have exactly same symptom as lewrossi and BCinc and I also own MacBook Pro late 2008 model with Lion installed.

  • Here is my setting in detail
  • MacBook Pro 15" (late 2008)
  • SanDisk Extreme 120 GB with R201 Firmware 
  • 8GB RAM
  • Lion 10.7.4
  • Use Optibay for an old HDD as secondary HDD
  • Trim is ON by Trim Enabler

I also wiped out everything and removed “Recover HD” and installed Snow Leopard but it also shows occational freezes so it’s not OS issue.  

It worked greatly for 1st day, and fine with several reboots but it seems it gets worse (and symptom started) after hit “hibernate mode” (over 70 min sleep).  

Cleaning cache by Onyx, Recreating Spotlight Index, Safeboot, PRAM clear, and I tried so many tips and tricks but none worked.  

Does anyone have any clue how to avoid this freeze, or improve the performance of this SSD?  Do we have a new firmware soon?

Or, since we have 3 people with MacBook Pro 2008 models have this problem, does that something to do with Mac Hardware issue?
