Very low performance, random read IOps is way low for an SSD. Try another SSD with a better controller; Indilinx is fair, but best is Intel X25-M 80GB or X25-V 40GB (same as some Kingston SSDnow V-series 40GB).
I would say that TRIM is a pretty desirable attributes for an SSD if you have Windows 7 and don't plan to use the drive in a RAID array (TRIM doesn't work if the SSDs are in a RAID set). I personally wouldn't buy an SSD without it.

For CrystalDiskMark the bottommost "4K" figures best represent the access time for the drives. (They don't actually say tell you what the access time is, but a drive with faster access times would score better in that test).
For the ATTO benchmark it would be the topmost "0.5" results (same comment as above).
