Freezes on MacBook w/ Lion with Intel 330 SSD I installed an Intel 330 SSD (120GB) in my MacBook (4,1) a few weeks ago. I reinstalled a fresh Mac OS X Lion (10.7.4) to make sure there are no issues with the new drive.

However, since then I encounter random and pretty frequent freezes (~10, daily).
The entire OS freezes for 10-30 seconds, the cursor (the infamous beach ball) still moves but no application responds to input.

I don't know whether the drive is malfunctioning or the problem is with the OS. I see other people having this issue and I'm wondering if anyone has any clues as to where to start investigating. If I am to return the drive, I need some proof that it's malfunctioning. Or, if the OS has incompatibility issues with Intel drives/SandForce controllers, I might buy a second different drive.

At the moment I'm trying to use fs_usage (as I'm writing this message), hoping to find a clue about what's causing the freezes.

As suggested by various blogs/tips, I disabled the power-saving feature for disk drives. I even tried the Trim Enabled utility, but it only seemed to make the freezes happen more often, so at the moment it's disabled.

Any input on this issue would be appreciated.
Turning off the FileVault seems to be fixing the problem with me. I also have TRIM enabled with Trim Enabler and "Put hard disk(s) to sleep when possible" in the Energy Saver setting unchecked.
