As you’ll no doubt know, I’ve recently bought two new computer, and built them up. I’ve settled on the Toshiba 3TB DT01ACA300 HDD as my drive of choice for these systems. I ran a few tests recently and found some interesting results. I haven’t published them here yet. My main test is a database load. I just take an 8GB text file and create a PostgreSQL database from it. The file in question is a dump of the FreshPorts database. Once loaded, it’s about 33GB on disk. I reckon this is a good decent test. It writes, it reads, it writes some more. It’s easily reproducible.

These tests took about 14.5 minutes to run.

Then I moved those HDD to another server. I planned to run the same tests there.

On this different server, the tests take 21 minutes. That’s a 50% performance hit.


In both cases, the HDD are attached to the M/B, as opposed to a SATA card.

The motherboards in question are:

fast one

not so fast one


I guess we can clearly state that the Intel Xeon is blazingly faster than the AMD Opteron. I just didn’t expect such a big difference.

Did I buy the wrong CPU for the other M/B?

  1. May be different SATA mode? AHCI vs IDE or another ?

  2. On the slower server, all the HDD are connected to a SATA card… Hopefully that’s running in SATA III mode. But that is something to investigate. Thank you.
