all my current storage drives are WD red.
in the past ive used seagate with no issues.
i usually buy on price/gb
Anything from a major manufacturer NAS rated.
I'm sure the IT pro's will be along to recommend something.
Not that I would know--
but the only "problem" is with the speed these smr drives operate,, its a risk thing, if one drive fails the risk is a second will fail while the first is being resilvered(rebuilt)
and if that happens---- its Exit Stage Left for all the data.
so the faster the first is resilvered the safer the system.
This scenario can be somewhat mitigated by buying HDDs from different lots and suppliers
Perhaps Sean will help me and let us know if its CPU speed or disc speed thats the major player here...

I assume you have an off the shelf unit from one of the NAS manufacturers (if it's one you built yourself I'd be guessing that you'd know what you needed).
If that's the case have a look on their website for a list of manufacturers and drives they support. In principle:
- try to match drives as closely as possible to your existing ones - same model is the perfect solution.
- if the model is no longer available match one with closest characteristics from the same manufacturer
- do not use a drive with a smaller capacity than the smallest you have
- if going larger, generally the NAS will not use additional capacity until all the other smaller drives are replaced with the same or lager capacity ==> wasting your money
- Don't mix CMR and SMR drives keep it all one way or the other ==> your drives are all CMR (good)
In your case I would get a Western Digital Red PRO of the same capacity. These are CMR drives so will be the best match for your existing drives.
Let me know if you have any questions.
EDIT: Actually, you can still get the standard non pro reds with CMR, what size drives do you have?
Cheers,

In this case it's the disk drive itself - SMR drives have to do a lot of additional data writes when handling large data writes:

In any system, conventional HDDs (as apposed to SSDs) are always the slowest part of any system - rarely will it be the CPU (speaking of disk I/O operations).Originally Posted by wikipedia

2008 called. They’d like their chipset back.
The old Northbridge/southbridge went away years ago. Regardless, in any generic motherboard based RAID (softraid) the work is done by the CPU anyway (ie either BIOS/EFI drivers until os bring up and then fakeraid in the driver).
Right now avoid the 2-6TB WD EFAX. I just picked up some 8TB purples to try something different although I do have a “few” CMR reds.
