Hello BC,

 

I've recently been doing some research in preparation for building myself a fileserver for my home network.  My goal is to have a RAID 6 array with between 5 and 8 drives and I am currently in the process of trying to decide which hard drives are the best bang for my buck.  In doing this research however, I have come across some people who suggest that using Western Digital reds in RAID arrays greater than 5 disks will either not work at all or will have a severe performance decrease as a result of the firmware on them.  I'm wondering if anyone else is aware of any problems like this or has knowledge in this area.  Your thoughts are appreciated!

No vibration sensors like a real enterprise drive.  You should, should, be OK if a provision for vibration insulation is taken.  Just don't hook all of them together solidly mounted to a rack and expect them to work to spec.

Yeah, the reds certainly do not have all of the bells and whistles that some of the other enterprise class drives do, but when building such a large array, the price point that REDs offer is certainly appealing. Given that their warranty is only 3 years however, the question becomes, is it really worth it? Or am I better off paying the extra and getting a real enterprise grade drive with a full 5 year warranty?

In doing this research, I've assembled a spreadsheet with some drives and some other metrics about their cost / reliability but I'm still not sure where my money is best spent :\

Also, regarding the original post, this thread was part of the reason why I became concerned about the Reds.  Perhaps there was some other underlying problem with the mobo/raid controller they were using, but the last thing I want to do is spend a bunch of money on drives and not be 100% sure that what I've designed will work.
