I don't really save much onto my MBP's SSD but I do run a lot of ram heavy tasks that do eat up virtual memory. The other day, I noticed my free capacity drop from over 70gigs down to 25! I figured it was likely the swap file. Even when I restart my mac, I don't get any space back. What is this thing that is eating my valuable SSD space?

I do have trim enabled on my crucial m4. Does the mac give me back capacity after it's done trimming? I leave my computer on idle overnight...
 
If you're wondering what "Other" category in the Lion storage tab is about, this may help explain:
For space issues not explained by the above, there are a few things you can try, some of which may or may not apply:
  • Begin by restarting your computer as a first step. This sometimes resolves issues.
  • For Time Machine users on notebooks running Lion, space may being consumed by Time Machine local snapshots, which can be disabled.

  • Search with Finder to see if the space is being consumed by a very large file or several large files. Adjust the 50GB in the illustration to whatever size you deem appropriate.

  • Use OmniDiskSweeper, JDisk Report, Disk Inventory X, DaisyDisk or GrandPerspective to see how space is being used on your drive. Some of these apps may show more detail than others, so try several.
  • Check your drive with Disk Utility: Using Disk Utility to verify or repair disks
  • Try re-indexing your drive: Spotlight: How to re-index folders or volumes
Here are a few resolutions found by others with the same question:
 
Fantastic Answer,

I would like to add that time machine local snapshots stay for 1 week maximum. So, if you deleted a large # of files, you'll only really free up space one week later (unless you start to fill up your drive, in which case the backups will be deleted to make room)
