Well y'all, looks like everything is running fine on my SSD now.
They did send me a 240GB drive by mistake! Everything says so, HDTune, ATTO, CheckDisk, Intel Drivers, etc, all say 240GB drive.
My WEI went up from 5.9 to 7.7 now after a couple of hours left at the logon screen and then shut-down overnight - after a reassessment, it jumped up to 7.7.
Boot time at the moment with all drivers installed and AVG running is between 25 and 27 seconds which is excellent. I expect that to go up a bit once I've got all my standard start-up programmes running (Skype, MSN, Steam, uTorrent, etc) but all is well.
My benchmarks on ATTO are a little lower than I'd like (230/240) but frankly, as someone who really is really interested in tech, but a bit of a numpty, that's good enough for me
