What is eating my SSD space?

[lbeck]

I have my OS and all my apps on a 120GB SSD. I keep all my data on separate internal drives. I do keep my user folder on my SSD, I have never moved it like some people do. I'd prefer to keep it on the SSD like the OS wants.

But no data is saved to the SSD, I keep my itunes and iphoto library on the other drives. But I' noticing that the space on my SSD goes down every week. Last week it was at 91 GB, today its at 88.55 GB. I made notes of the four folders and their sizes last week. The only one that has really changed was the User folder, it went up 1GB. A few questions ...

1. What would make my User Folder go up 1GB if I'm not saving data to it?
2. Where has the other 1.5GB gone?

I've used Onyx to clean out pref files and such but that only gained me back a little space. What is causing this storage loss?

I have a few, they all take up space. Have you tried resetting to see what it does to the SSD space?

I meant resetting your Mac, but if you do that every night anyway.

So you restart your computer and not just wake it from sleep?

Yes, I have it on a schedule to shut down every night and wake up every morning. No need for it to be on when I'm sleeping

Disk Inventory X is another useful tool to see what is taking up space.

I've been using Omni Disc Sweeper and it does a great job. I just dont know if I can delete some things.

I know I can delete most Cache files. What about MobileSync Backup folders?

It's a good idea to move the user folder to a HDD. It could get bulky very quick in some case. Like Safari's top site, it genera 2 thumbnail image for every web page you visit. 1 jpg, 1 png each page. It could easily grow into serval GB for top site's thumbnail folder alone.

This is definitely not MLC SSD friendly.
