Actually http://www.scsifaq.org is the place... SR has good drive reviews and some useful 'white papers' and other articles. But they aren't infallible: case in point - their recent review of the Seagate 7200.8 SATA drive.

They didn't test in TCQ mode. When not in TCQ mode, the 7200.8 is locked in AA mode thus perfomance was worse than the earlier version in many of their tests. Worse is the fact that they apparently never checked with Seagate to find out why their tests didn't even approach what would be expected considering Seagate's published specs. Pretty sorry, IMO.

Probably because the drive doesn't support TCQ. SR isn't a bunch of miracle workers.

If you mean NCQ, then yes they did:

"Some may point out that the 7200.8 supports SATA NCQ and that the drive's performance is not fully realized without mating it to an appropriate controller. When paired with a Promise FastTrak TX4200, Seagate's latest indeed exhibits some improvement in multi-user scenarios. For non-server use, however, it's a wash. The curious may peek at the differences in the SR Performance Database."

Look at that amazing performance boost NCQ is giving desktop users. I own a 7200.8, and it is every bit as slow as the SR review shows. I bought it for cheap storage though, so the performance is largely irrelevant.

SR tests drives in their default configurations as they should be since that's how the majority of users will use the drives. You don't see Anand testing video cards overclocked with third party driver hacks and tweaked out systems and using that as the default setup for his reviews.
