Can I install a 4TB drive in my ReadyNas Duo v2?

Are you certain you have a v2? The labels can be misleading, there is a definitive guide here: http://www.rnasguide.com/2012/01/09/how ... -or-nv-v2/ (Enough folks make mistakes on this to make it worth confirming).

Yep, I've a Duo v2.

;)

Thx.

On the disk capacity -

With default xraid2, 2x2TB gives you about a 2TB volume, because one disk is used for RAID redundancy. You can configure it as two independent volumes of 2 TB each if you wish (not using the redundancy feature).

Netgear hasn't tested/evaluated 4 TB drives for the v2. Some models might well work - technically there is no barrier - though if you use them Netgear might deny support.

I'd be surprised if they added more drives to the V2 HCL, since they are moving on to the new OS6 platform. Though they have surprised me before...

On USB, you can share an attached drive. Performance will likely be a lot slower than than the internal drives. When you get to that point, you could also get a second (or larger) NAS.

Thank you for your reply, first of all. ;)

Well, actually, I'm using my nas with 2x2TB in JBOD mode. I don't need redundancy since i've no important data to backup. I'm using the nas to stream my movie collection.

About USB drives and performace, can i ask how much slower will be the attached drive? So slow to not stream hd movies and videos?

I'm not a v2 owner, so I have no way to measure it. I'd expect it would still be enough to stream HD. Streaming doesn't require much performance (8 MB/s is enough for full BluRay).

Maybe someone who is an owner can give you more info (possibly including specific USB drives that work well).
