Thanks for the tips, guys. I left my laptop on overnight on the log on screen with ~40 gig free and I could see SSD activity, hopefully for garbage collection.
As far as benchmarks go, I was just launching AS 4K write test for a bunch of seconds to see the speed and then aborted. Last check was giving me a relatively constant 5MB/s for ~20 seconds, which is already way better than I had with a more loaded disk.
Also, real life performance seems to have gotten better - I could paste a ~4GB file with almost constant 20MB/s write speed today. No extreme slow downs that used tohappen after 10 or so seconds.
Looks like I'll have to live with the drive, making sure that 30-40GB is empty. It works kinda fine like that. As soon as I'll be able to remove more data I'll try shrinking the partition by ~20GB too.
I gained a lot of insight about how SSDs work because of this whole thing. Next time I'll buy me a new gen one with some extra storage too.

So you've done disk cleanups with CCleaner, or just Windows disk cleanup? Ever remove old restore points? Is the Recycle bin empty?
Yes, logoff the PC overnight while plugged in, that should cause any GC in the SSD to wake up.
It's Windows 7 64 bit, but the firmware upgrade available through Lenovo's firmware update software doesn't support TRIM - I installed it. Apparently it only improves wear leveling.
The method for guerilla-installing TRIM enabling software isn't working, it's crashing the installer before the update starts.
I'm sure TRIM is not working because it's greyed out in Crystal Disk info and HD Tune Pro.
I turned off restore points and the Recycle bin is empty, yes. I empty it manually every time I delete a file.
I did cleanups using Windows and then CCleaner.

D/L it and run the "Performance Optimization", which is a manual way of triggering and running GC/TRIM on your drive. The program will also allow you to PROPERLY over-provision your drive; that doesn't mean just keeping it less than 80% full, it means blocking your ability to utilize 20% of the drive, keeping it as "spare" space to enhance performance and life (and you should still keep the drive less than 80% full, even if it is now technically 80% of 80%)
The drive actually preceeds the 470. It's 2nd gen SSD from Samsung made in 2008 or 2009.
Thanks, didn't know there was Samsung's software for that. I'll try.
edit: Magician says it doesn't detect a Samsung SSD on my computer, so it doesn't work with my drive. I guess it's too old oO.Edited by szymon247 - 7/17/13 at 4:47pm
