Readynas rn316/rn516 with WD 3.5" Red NAS 8TB WD80EFZX
Hello i am looking go purchse a nas either a n516 or a n316, Can they take the WD 3.5" Red NAS 8TB WD80EFZX 128M SATA3 HDD Can you confirm if these will work i note you have limited options int the...

I do not have those disks, so I can't answer whether they work fine with the NAS or not. They are not listed on the compatibility list anyway:
http://kb.netgear.com/app/answers/detail/a_id/20641/~/readynas-hard-disk-compatibility-list?cid=wmt_netgear_organic
They work in my RN102 and my RN202, so I see no reason why they won't work in the x86 NAS. The side holes are aligned with the pins on the tool-less plastic inserts on the disk tray.
Although the drives aren't on the HCL today, it would be pretty shocking if they aren't added soon.
I would also be interested to know for the RN316 with these drives - WD Red (NAS) 3.5" 8TB WD80EFZX (5400RPM 128M SATA3), I'm looking at upgrading mine with these too...
WD claims the RED series are NAS compatible Drives (ie not desktop drives), but do not list this specific 8TB model as tested for Netgear RN 316 yet? found here: http://www.wdc.com/en/products/products.aspx?id=810 - this page claims the following for the RED class of drives (italic'd to highlight):
"Fill your NAS with WD Red, then fill it with awesome.
There's an industry-leading WD Red drive for every compatible NAS system to help fulfill your data storage needs. With drives up to 8TB, WD Red offers a wide array of solutions for customers looking to build the biggest, best-performing NAS storage solution. Built for single-bay to 8-bay NAS systems, WD Red packs the power to store your precious data in one powerhouse unit. With WD Red, you're ready for what's next"
But I also found the following from here: http://support.wdc.com/KnowledgeBase/answer.aspx?ID=996 (possibly old?)
"Critical: WD Blue, Green, Red or Black hard drives are not recommended for and are not warranted for use in RAID environments utilizing Enterprise HBAs and/or expanders and in multi-bay chassis, as they are not designed for, nor tested in, these specific types of RAID applications. For all Business Critical RAID applications, please consider WD’s Enterprise Hard Drives that are specifically designed with RAID-specific, time-limited error recovery (TLER), are tested extensively in 24x7 RAID applications, and include features like enhanced RAFF technology and thermal extended burn-in testing. "
Erm, do Netgear use Enterprise HBA's and/or expanders or multi-bay chassis in the RN316? Talk about WD confusion lol
Anyhow, I note that Netgear have currently NOT listed them as tested/confirmed compatible drives (yet?) - see: http://kb.netgear.com/app/answers/detail/a_id/20641/~/readynas-hard-disk-compatibility-list - but they don't seem to have many 8TB drives tested either....
I've also noticed Netgear strongly recommends drives with a Rotation Vibration Safeguard feature, which the WD80EFZX doesn't seem to have specified (presumedly not a feature then), is it a requirement or just a recommendation guideline when not listed yet?
For them to be listed, do WD and/or NG do the testing? Does it take some time to perform? Are they based on manufacture (ie WD) specs first, then tested? Keeping in mind, these are pretty new drives.....
My main concern is compatibility and logevity of using such drives with 24x7 automation on a RN 316 with relatively low-medium use for around 3-5 users during the day (other RED's are listed, just not these...only because of no testing done yet?)
I was reading weinelm's post on WD80EFZX with ReadyNAS Ultra 2 here other than having some possible noise issues (vibration/fan/RPM issue?), otherwise working fine on that RN.
Sorry for the barraige of questions, but if some could be answered that would be great.
*correction: Presumedly all the RED series drives from WD have Rotation Vibration Safeguard since all the WD RED's on the Netgear Compatilty list have it. All drives for WD RED specs are here, including WD80EFZX.

All WDC Reds are designed for for use in multi-bay NAS systems and per http://www.wdc.com/en/products/products.aspx?id=810 have features to handle noise and vibration.

Clearly the RN316 is a multi-bay chassis. The Reds are intended for use in up to 8 bays.
They are not enterprise-class though (if you want that, you should be looking at the Red Pro WD8001FFWX or maybe the gold WD8002FRYZ. Both are a lot more expensive than the WD80EFZX. They are higher performance, but also run hotter/use more power. I don't think you'll see much better performance with the RN316, you generally are limited by your home network, not the drive speed.
Personally I've had good luck with the "ordinary" Reds, and I see no reason to think that the 8 TB drives I deployed a couple months ago will be less reliable than the other sizes I was already using. That said, drive reliability does vary by model, and these are pretty new drives.
Also, my RN202 (8 TB + 6 TB drives) is in my home office, and I find it to be very quiet.

I believe Netgear tests, and they are extremely slow. Of course they do have a lot of NAS models to test against - personally I think they should just say "use NAS-purposed or Enterprise drives" and be done with it.
How long did it take for it to rebuild on the 8tb (1 at a time)? I have 4tb drives atm at 85% full using RaidX....so i can expect a few days per 8tb drive upgrade for me?
The time roughly scales with the used total disk space (including parity blocks).
So the first one will be the same speed as a 4 TB replacement, since the system ignores the extra capacity. I don't own an rn316, but I am estimating that is about 20-24 hours for single redundancy 6x4TB volume. The time will climb as you add more disks, with the 6th one taking about 2x the time of the first. Though installing 3 of these drives would reduce your volume usage to about 60% - you don't need to upgrade all 6 at once.
It would be faster to do a reset with all the disks in place, and then restore the data from backup. If you are replacing all 6, then a reset would also let you switch to dual redundancy (if you aren't using that already). Note if you have a spare slot, then you can switch to dual redundancy w/o a reset - and would need to have at least four 8 TB drives installed to see a size increase.
