my main pool is filling up, I have to buy new HDDs.
I have 6x4TB RED plus and am looking at 6x8TB or 6x10TB
WD Gold are surprisingly cheap, only slightly more expensive and seem mighty good as compare to WD Red Plus (5y warranty, speed, TBW etc.)
(WD NAS Red Pro are the most expensive surprisingly)
WD NAS Red Plus 8GB are priced
189€ vs WD Gold 202€
For 10Gb, it’s even closer:
WD101EFBX 242€ vs WD Gold 248€
At these prices, I’m just wondering if there are any reasons not to go for it.
Drawbacks I know of:
- noise (my machines are in the cellar, I don’t really care, I think)
- power draw
- heat ? will I need better fans?
- ???
I’m pretty sure I don’t need the extra speed for my use case though, especially as I’ll make a 3times 2way mirror pool with the old 4TB drives, and will allocate storage accordingly (VM vs cold storage -movies, archive files etc.)
Max operating temp on golds is 5c less (60c max), golds use ~2watts more power in whatever WD uses to measure average operational usage, golds though have 2 years of extra warranty.
Both are CMR, so just go with whatever is cheaper imo.
Only thing to watch out for is if you had an anemic PSU previously, adding more hard drives might put too much stress on the 3.3v & 5v power rails (generally the total wattage on the PSU is for 12v power only; not always though - check the max wattage for your specific PSU’s rails & do some math).
Edit:
As always make sure to perform burn-ins on new drives.

Thanks for this, I bought the WD Gold in the end.

Are you sure that the 3.3V bus is affected in any appreciable manner via adding hard drives? SATA backplanes in my Lian Li case only supply 5V and 12V to the drives. Granted, there might be some additional power draw associated with communicating with said drives, but that power draw likely pales in comparison to the power drawn by the drives on the 5V and especially the 12V bus.

Fair point - I actually don’t, nor could I find a break down of how the hdd uses the wattages.
