The first set of benchmarks were run without doing any modifications on the Velociraptors with the exception of RAIDing them together. This is done in the bios of the motherboard. The settings that I selected for the RAID were RAID 0 with 128 KB stripe size.
Second set of tests were doing with a mod similar to the one in the Seagate Mod Article we published some time ago. After deleting the RAID partition and resetting the drives, I proceeded to downsize the drives to about 1/2 their original capacity – approximately 300 GB give or take. This was done with a software from Seagate (Seagate Tools) DOS Version (not Windows Version).
Steps to short stroke your drive:
- To do this you first have download the Seagate Tools which can be found here.
- After downloading the .iso burn the iso onto a CD with any program.
- Insert the CD into the your CD/DVD/Blu Ray/..etc drive and restart your computer.
- Assuming your system is configured to look at your drive before loading the Operating System, you should see a window that lists all the drives in your system.
- Select the first Velociraptor drive and go to the Toolbar>Advanced>Set LBA number. The software will tell you the maximum amount of LBAs your drive has, whatever that number is = MAX advertised capacity of the drive in the case of the Velociraptor that number is ??? this equates to about 600.1 GB. Dividing LBA number by 2 will yield our desired hard drive capacity (~300 GB).
- Enter that number into the box and press enter.
- For the second drive repeat steps 5 and 6.
I used the following benchmarks in for all the tests I ran on the drives:
