3TB drive compatibility?
I own a ReadyNAS Duo with a pair of 1.5 TB drives. It is starting to get full so I am considering upgrading the drives. I could upgrade to 2TB drives, but that seems like a lot of cost and effort f...
When you look at cost I don't think spending the money on 3tb drives is going to be a good idea.
They are going to be expensive as all get out, and the 2tb drives are dropping lower and lower.
I was at Fry's Electronics today and saw some Hitachi 2tb drives for just over $100.
The way I look at it if you are connecting drives in a NAS, the Duo, or a two bay is the least
expensive, but the least efficient way to do that. With every bay you get the versatility of
your device is going to increase.
For 2 3tb drives you might pay $300 a piece when they just come out.
You might consider buying a better NAS ... something like the ReadyNas NV 4bay, or
even springing for the great performing ReadyNAS Pioneer Pro. Also ... you can consider
other alternatives like the DLink DNS-343 a 4 bay NAS that works pretty well, or even
QNAP. The DLink is probably the best buy for efficiency unless you want really high
performance or addon services.
The readynas lets you dynamically add disks, so you can start with the 2tb and add
new disks. bhy the time it is filled up you can upgrade to the 3tb which will be cheaper.
Also ... bear in mind with RAID5 you get to actually use more of the disk space you
buy ... assuming you are set up redundantly, which is really the only way to set
these things up, unless you do not care about your data.
Every bay you add you get more of each disk contributed to actual storage ...
the ratio (n-1)/(n) approaches 1 as you add more bays ... so with 2 disks,
mirrored you use 1/2 the total space that you buy ... but with 4 disks you
use 3/4 of the disk space that you buy. With the 6 bays in my readynas
pioneer pro i get to utilize 5/6 or my disk space ... or 83% ... that is where
the real savings are.
Think about it, the mirroed 2 bays are not so great anyway .... you are in a scenario
where you could benefit from upgrading your hardware.
The migration can be tricky though ... and moving lots of data can take a long time.
I have 2 readynas nv+, one dlink-dns323, one dlink-dns343, one qnap-ts409,
and a readynas pioneer pro.
