Does the low speed at the front of the SSD seem suspicious?

Yes, very. All of the numbers are actually very low on your SSD.

If you run ReadSpeed with the ident flag, it will show the interface speed and the disk speed. This should show if your SSD, which should be capable for 500 + is on a slower SATA II interface.

"rs.exe /ident"

Here's the output when I run "rs.exe /ident":

The 6.0 under Driv and Link indicate SATA III for both. Has this drive had a lot of use?

The figures for the 3TB drive look acceptable, but the ones for the SSD look far too low. I would expect 500+ for an SSD on SATA III, unless it has had a very hard life.
