Do you mind to perform some testing under Windows?
For Windows there are a lot of utilities like CrystalDiskMark, HDTach, etc. that should give us some more information.

OK, I am game, but I don't really have any Windoze licences. Which version of Windoze do you recommend, anyway?

You can try Windows XP Home, but it does not really matter which one.

OK, got some XP. I will try and set it up and benchmark it.

Have you actually benchmarked any SSD's, just for reference?

Yes, this is why I suggested you to do it too: viewtopic.php?f=27&t=1241&start=10
I got anything between 70 MB/s and 90 MB/s, depending on the SSD used.

FWIW, I replaced the SSD with a regular 2.5" 120GB HDD (Seagate ST9120823ASG 7200.2), and retested under Ubuntu.

Got the exact same results as I did with the SSD: about 60MB/sec max (seq. read). This is same result as noted in this post with the CompuLab stock 2.5" 160GB SATA HDD.

Strange that I did not see any performance improvement between the SSD and HDD. As mentioned, the same SSD in other machines can do almost 200MB/sec. In summary, I was not able to reproduce your 90MB/sec SSD read spec under Linux.

You tested using CrystalDiskMark / Windows. Could the bottleneck be a driver/OS issue?

Indeed it could be a driver/OS issue. This is why I still suggest you try it with Windows.

you will never get anything above 90-100MB/s, because limitation of the chipset
