Good point... I will have to check that.
I knew that there were different label colors but I didn't know that the label color would make a noticeable difference in speed.
the one that I am using now in this test is a 2TB Green Drive and my OS drive is a Blue. THe donor (Suspect) drive that I am using in all the tests is a Hitachi.
Just FYI...
WD Green and Red drives are not 7200 RPM drives, they are "Intellipower" RPM drives. Seriously, if you look at the specs under spindle speed, you'll see "Intellipower," as if that were a measurement of spindle speed. WD isn't saying, but what Intellipower is presumed to mean is the spindle speed is variable between 4500 RPM and 7200 RPM. This is to save power by not spinning the disk as fast during periods of low activity.
I use a Green drive in my home computer for media storage. It's perfect for that. For forensic purposes, I'd never use a Green drive. It may be okay for imaging because the source drive may be slower than even a Green drive. However, if you intend to use the Green drive to do your analysis from, you'll experience noticable performance penalties compared to a Black drive. Access times are slower, and as far as I know, there is no way to force a higher speed, so it's up to the drive's firmware to manage your performance.
Since I mentioned Red, I don't use Reds in a RAID. Although that's what they're designed for, the WD Black Enterprise drives are much better suited, and have a much better unrecoverable error rate, which means you have a much better chance of a successful rebuild after a drive failure. But this is a subject for another conversation.
