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

For those with issues on a 2008 Mac, there is a known issue of incompatibility with nVidia chipsets and Sandforce based drives. This may be the reason you are seeing this. You could try disabling sleep hard drive under power settings to see if this makes a difference - especially when you say these issues started for you after hibernation.

Thanks donka for your tip. As of taking your advice, avoid using nVidia graphic card, my MacBook Pro late 2008 is back alive with lighting fast speed!
This is what I did to avoid those "occasional freezes" and it does NOT even require clean install (sweet!)
With this settings, my MBP2008 boots within 4 gear spins and everything seems working great! It's been nealy 40 hours since the new settings, 4 reboots, 3 hibernations, my MBP still works great.
BTW, I still keep the setting of "Put the hard disk(s) to sleep when possible" to trigger hibernate. Yes, it takes about 20-30 seconds to come back from deep sleep but occational sleep does not happen with this setting.
This may or may not work for other MacBook Pro late 2008 models, but it sure fixed my issue. I'll look more into those secondary monitor issue if that really causes occational freezes.
Extra: Other settings I performed
- Disable chache for Safari
- Spotlight only against Mail
- Disable "noatime"
- Safeboot and Verify Disk (no error)
- PRAM Reset (it did not fix the problem before "Better Battery life" was set)

Cool. I also disabled the hibernation file which means going to sleep or waking up is instant as the system is not writing the 8GB file (size of RAM) each time.

donka, I don't against that idea but it will cause losing data if my MBP runs out of battery completely (and I occationally do while using it outside for visiting my clients)
I better stick with hibernation enabled but people who is connected with power cable 24/7, it's good idea to disable it for faster wake up and not waste size of sleepimage file which is size of RAM you have on MBP

Yip, it all depends on how you use your MBP. With auto save you theoretically should not lose any work if you did run out of battery power but having the extra backup of the hibernation file offers more security and peace of mind.

Extreme 120 installed in my ASUS G73JH with Win 7, freeze intermittently especially running "Create AAC version" audio in Itune and VOIP dialling. It just freeze and hang my whole system without error or blue screen. Force start to resume my system, I've done all your advise in the forums but problem still persist.

is sandisk support even reading this?

Too bad there is no such setting or icon in my system preferences. I see have two sliders 'computer sleep' and 'display sleep', however no icons.
Also, I wonder if disabling the nVidia doesn't affect performances? I regularly use it for editing video so I need all the power I can get.
Another thing is the SSD started making strange sisling noises, kinda like old hard drives did after a while.

I'm getting the same issue here. The system worked fine for about a week and then just started stalling for a minute at a time, then runnng ok, then stalling again.
System details are
Sandisk extreme 240gb ssd with firmware R201
running in IDE (will check with AHCI when i get the chance)
Gigabyte P55-US3L (rev2.0) with latest firmware
AMD 6850 Graphics card (not Nvidia as people have suggested that might cause issues)
Trim is enabled, defrag is disabled.
Note that the system works flawlessly off a hard disk, it's only when booted from the SSD that there is an issue.
