Western digital velociraptor

OK, the results are in - although this first run isn’t entirely fair as the velociraptor is on a different controller to the other drives - I’ve an Asus P5B board that has four channels on the main controller and then has a couple of IDE to go with the jmicron SATA. The velociraptor is on the jmicron and is the system drive as well, so get’s blips as the OS hits the drive :frowning: I’ll do a better test perhaps if people are interested.

Drive 1
The original 74Gb SATA150 western digital raptor

HD Tune: WDC WD740ADFD-00NLR1 Benchmark

Transfer Rate Maximum : 79.8 MB/sec
Transfer Rate Average : 68.3 MB/sec
Access Time           : 8.2 ms
Burst Rate            : 115.0 MB/sec
CPU Usage             : 1.1%

Drive 2
A Maxtor 300Gb storage and ‘temp’ drive

HD Tune: Maxtor 6B300S0 Benchmark

Burst Rate            : 109.9 MB/sec
CPU Usage             : 0.9%

Drive 3
Here’s the surprise out the bunch, the 1Tb Western Digital ‘green power’ drive that I used for storing VM image files for work and archiving projects. I will be adding another one of these to create a mirror raid.

HD Tune: WDC WD10EACS-65D6B0 Benchmark

Transfer Rate Minimum : 44.5 MB/sec
Transfer Rate Maximum : 94.6 MB/sec
Transfer Rate Average : 75.8 MB/sec
Access Time           : 20.4 ms
Burst Rate            : 148.6 MB/sec
CPU Usage             : 1.5%

Drive 4
The one I’m quite impressed with the general snappyness of the OS, but as I said I know you get that from a clean install anyway - but moving large files and unzipping stored Virtual Machines was very nippy.

HD Tune: WDC WD3000GLFS-01F8U Benchmark

Transfer Rate Minimum : 13.3 MB/sec
Transfer Rate Maximum : 117.3 MB/sec
Transfer Rate Average : 97.7 MB/sec
Access Time           : 7.1 ms
Burst Rate            : 141.5 MB/sec
CPU Usage             : 2.3%

There’s a blip it would seem everytime I run the test at about 20% of the way through where you would not expect there to be a drop in the transfer rate, it plummets down to 13.3 - in Vista with the process manager I could see if another process accessed the drive, but having ran it twice now, I’m not convinced that’s the issue. With more time and a few more moments of playing I’ll make sure, for now it’ll get the WD fitness test, after all this was an Ebay purchase :wink:
