k1114 :
Sata 1 ssds will be really buggy, it was a new technology then. Even if you could find them, I wouldn't recommend it but you shouldn't have any issues with a sata 2/3 ssd. The newer ssds will be faster but it's negligible in normal pc uses, they will all be about the same. You would need to say which models to have solid info. The advent 6555 should be sata 2, I can't really find the info but with the cpu, q9000, the compatible chipset has sata 2.
Thanks for the info, the machine was a good buy at £550 and I already have a SSD in there, the Samsung MMCRE28G, the AS SSD benchmark has it as 187MB/s read, 20 MB/s write, which is pretty poor on the writing side hence I am keen to upgrade the disk if I can (working at a .com just now and have to use my own kit, lots of compiling, 10 min ant tasks etc).
The exact details of the 6555 are hazy, as you would expect from anything from PC world;
http/www.adventsupport.com/viewtopic.php?f=1&t=4736&p=11629&hilit=6555#p11629
it is described as "Advent 6555 === MicroStar 1722 chassis (similar to Microstar GT725)"
And the description of the 1722 certain seems a good fit;

If it is a 1722, then there is a good chance it has SATA2 support

But so far this is the only post that mentioned it so I am not being over-hopeful, I have seen other posts that identify it as SATA 150
. I can't see anything from the usual windows device manager that indicates one way or ther other and needless to say, the official PC World / techGuys resources are worthless.
The 1722 is also said to be similar to the MSI GX720

and again, exactly which SATA controller, not sure.
I am tempted with a cheap SATA3 since there is little price difference and they are easier to get hold of. If I do I will share my findings
<or mistakes>
