Has anyone here noticed a significant variation in performance among Raptor 36gb drives?
The caveat is I just ran across this, and I do need to investigate more fully. It is very possible it has something to do with this particular RAID controller, a cabling issue, or some other factor.
It seems though at this time I have a significant variation in performance between two Raptor 36gb hard drives.
Basically, I was confidence/performance testing a RAID controller that is different from what I normally use. For my purposes I have a somewhat standardized procedure I go through with new/unkown parts/configurations. Part of that procedure involves performing timed tests with multiple drives in various configurations.
Some of the tests were coming out with timings that were way off what I expected. (Based ONLY upon previous tests performed in my environment/configurations.) My preliminary conclusion is that one of the two Raptor hard drives I was using seems to be running slow? (About 1/2 as fast.)
I DEFINATELY need to look at this more closely, and will in the next couple of weeks.
While I DON'T test every drive I receive, I have purchased around 12 Raptor 36gb hard drives and haven't really noticed this before.
The ones I am using for this test, are just spares that were sitting on my shelf. While both drives have been in use before I don't have any specific information on previous performance in my environment.
Based on the label, both drives are the same model and are dated with the same date. (I haven't looked to determine if this is manufacturing date, but that is what I would suspect.)
Edit - Changed subject working from "speed" to "performance".
