HDD benchmark competition - inaccuracy?

post #1 of 2
Thread Starter 
Does anyone else think this competition is inaccurate? What I don't get is these burst speeds that exceed the interface speeds for the drives.

Lets take the highest score on the burst column of 3613MB/sec. That's with 3 Western Digital Raptor drives, which operate at SATA150. The INTERFACE that they are connected to is at 150MB/sec. How in the world is that person exceeding the combined interface bandwidth on 3 drives (450MB/sec)? I mean really, they're exceeding it by 8X. This competition reeks of caching problems. Even if they were the new velociraptors, operating at SATA300 (300MB/sec), 3 drives would provide a PEAK capacity of 900MB/sec.

I think we should be looking for a different test to benchmark, as the ones here appear to be poisoned by system RAM caching.

That burst speed problem is an error in HDtach, i updated my drivers and suddenly my Burst speed was in the thousands, just ignore it will hdtach gets updated.
