Seagate Barracuda 7200.9 500GB SATA 3.0 Gb/s Hard Drive
November 10, 2005

Testing (continued):

Real World File Transfers - The real world performance testing was restricted to the two 500GB SATA 3 Gb/s drives. Mainly this was due to the fact that both 7200.8 Barracudas were in RAID 0 mode in order to provide the quickest interface for reading/writing data, and the Maxtor drive was holding the operating system.

In the this round of tests, 8 DivX files (totaling 5.48GB), were copied from the RAID array to each 500GB SATA 3 Gb/s drive and then copied back to the RAID array. The total time was recorded for the transfers, and this was then converted into a transfer rate (in MB/s). A reboot was issued between each transfer.


As you can see in the chart above, the Seagate drive beats the Hitachi drive by a decent margin in both the read and write portion of the real world testing.

Thermal Testing - The final portion of testing involved monitoring the drive's skin temperature while at idle and under a decent load. A thermal probe from a Cooler Master AeroGate was used to monitor the skin temperature of each drive. The probe was placed on the side of the drive, roughly at the center of the surface. The chart below details the maximum sustained temperatures achieved while the drives were powered on but inactive (Idle), and while the drives were under stress due to the testing (Active). Ambient conditions were maintained at 22.2C throughout the testing, as reported by other channels of the AeroGate. No cooling fans were directed onto the drives.


As you can see, the Barracuda 7200.9 drive runs the warmest of all units on hand, but the temperatures weren't anything to be alarmed about. Adding even one low speed cooling fan would do wonders for the temperatures of all drives tested, and even the warmest temperatures could be brought down by double digits.

Bonus Testing - As a little bonus, and to satisfy my curiosity about what a 1 TB SATA 3 Gb/s RAID 0 array might be capable of, I set up the Hitachi Deskstar and the Seagate 7200.9 Barracuda. Click the image below to see more details about what HD Tach reports regarding this array... Bursting to 359.2 MB/s and sustaining 101.0 MB/s is pretty impressive to me!
