[Hidden-tech] external hard drive system

[Rich@OTN]

Personally I've picked bigger units (# of drives) and this is a more 
complex Q, whose ?
I like Drobo,  while it is less standard technology, they allow adding 
drives (or replacing) as you go, of different sizes (usually getting bigger)
and can even add another layer of duplication depending on number of drives.

Bottom line, the bigger the drive, the worse the cost ($ and data) of 
loss potential.
Since you didn't put a price on it or any sense of your in-house 
technology) - it's hard to advise more.
Going beyond simple mirroring is usually worth the cost.

Given that we have a number of personal computers and even local web/db 
servers used for projects.
I much prefer NAS - that way you have much more flexibility and are not 
tied to a specific computer,
THAT will crap out a some point -- using only Windows mirror I would 
totally avoid.

Note: NAS drives is a reliability measure -- true NAS drives are for 
using in regular operations vs lower level drives that are mainly for 
backup and a good NAS unit will even turn the drives off when not used 
for some time period.

Where as NAS device means it's on a local network - with if you have any 
connection and wifi you (probably) have even if you don't know it.

Here is a good graph given by the Drobo people:

If you go with a higher end system, it's worth getting the extended 
service - after all this is about saving your data,
for an extended time.

BTW - I have about 42 Tb on 2 drobo units.
