My NV+ has been throwing a series of gradually increasing reallocated sector counts for going on two months, so I plan to buy a replacement HDD to have on stand-by for when the other shoe drops. The fact that I'm running, not just an NV+, but also an NV, is a clue that I'm keen on my hardware lasting a long time, so I'd like to hear views on which are the longest-lived 2TB HDDs. The 1TB Hitachis in my NV are beyond 50,000 hours power-on time, still going strong, which I consider outstanding. Performance is a second-tier concern, and I would prefer to stay away from WD (too many warranty disputes with them).
This is slightly OT but, since you're already here, :wink: I seem to recall some time back that 2TB would forever be the max size for an NV+ (v.1) HDD. Yes? And what about the NV? It also will accept 2TB HDDs, provided the firmware is recent enough, will it not?
Are you aware of the various issues regarding expansion to the 2TB capacity if your NAS is an older one? Be sure to read this topic: http://www.readynas.com/forum/viewtopic.php?f=66&t=75153, as well as this: http://www.rnasguide.com/2011/06/22/why-you-might-want-to-factory-reset-a-sparc-readynas/ Also, see the HCL at http://kb.netgear.com/app/answers/detail/a_id/20641. Lastly, there's this: http://note-to-self.baker.com/2012/12/21/netgear-readynas-nv-v1-vs-nv-v2-and-2tb-vs-3tb-hdd/
Note that the author of the last article recommends the WD RED 2TB HDDs for the NV+ (v1), but it NOT on the HCL.
Thanks for that, seezee. Yes, I am aware, but I'm about to post in the installations and upgrades forum for clarification on that point.
And as a continuation to my earlier post (something I forgot to ask), IIRC from the last time I did this, if I'm adding a blank HDD to an array, it should be cold-plugged, but a used disk should be hot-plugged.
For instance, the HDDs in my NV+ are larger than those in my NV, so I plan to hand them down from the NV+ to the NV as they are replaced. If memory serves, when I put the new 2TB HDD in the NV+, it should be cold-plugged, but when I migrate the 1.5TB drives to the NV, because they already have been written to, they should be hot-plugged. Am I close?
The only reason not to hot add a disk is if you are trying to preserve data on the disk, or if you are about to boot into factory. If you are adding a new disk it's always better to hot add it, whether as an additional disk or replacing a smaller or broken disk,
If you are planning to move all the 1.5 tb disks to the nv at once then you'd want to remove them from the nv+ Off, and add them in the same order to the nv while off. You won't be able to move one at a time and preserve data on them.
Personally I'd stay away from Seagate. I had 2 1TB Barracuda's die within 2 days of each other. Lost 1 disk on a Friday, went out to buy a replacement for it on Saturday, got home and another had died. Go figure.. first one had over 100 reallocated sector counts, the other hand less than 10. Lost everything. A dd-rescue didn't work.
