Just run it on my Intel G2 80GB.
Seq results were nearly identical
However I got 19.99MB/s read and 41.22MB/s write for the 4k tests
4k-64 ~identical
Both seeks came out as 0.107ms for me.
Based on that, i'd say your 4k results and seek times seem sub par.
Try downloading the
Intel SSD toolbox
Install, run and go into the "Intel SSD Management tools" section
In there it has three tools, one to optimise your ssd (forces a trim operation as i understand it - the software recommends running once a week and you can schedule it from here should you want to), one to check your OS is setup right (corrects if not), and one to erase everything (sugest not using this one

).
the software also features a SMART data reader, gives you drive info and can run diagnostic scans
EDIT: As mentioned below it also depends on the SATA controller being used - for reference I am using one of the secondary controllers on my motherboard - either the gigabyte sata2 chip or the marvel sata 3 chip (i cant remember) as the X58/ICH10R sockets are being used for some arrays. i suspect this may have a small performance hit but its negligible.
