Intel 320-series SSDs have an obscure bug in their firmware that can cause them to change from a multi-gigabyte SSD to an 8 MB pumpkin. Intel finally found the issue and posted a fix.

This might explain why supplies of Intel 320s have been a bit sporadic lately. If you have an Intel 320, get ready to download and install the update. You may want to wait just a few days to make sure there are no issues with it, as SSD updates in general tend to be, shall I say, rushed.
