DAS is direct-attached-storage. I don't think you want that.
Depends. If it fits in the safe, and can be connected using one of these
eSATA thingy connectors, it might be a very good choice.
Synology (sp?) is sort of a big name in home & small office NAS boxes.
You can buy the boxes with or without drives. I suspect you won't like
the prices.
I've been looking :-) I think the empty box costs more than the drives
you're going to put in it ...
I wonder if you might consider what data on your backups needs to be
immediately available and which doesn't. Possibly buy an 8TB USB drive,
take a bunch of the lower priority data off of your current backup thus
system freeing space and move on from there?
I built my NAS devices using old computers ala Wol's suggestion to me
maybe a year ago. They work for me but don't have the fastest network
interfaces.
I get the impression Dale isn't actually PLANNING his disk storage. It's
just a case of "help I'm downloading all this stuff where do I put it!!!"
How much storage do you have in your actual computer? How much space do
you need IN ONE PARTITION? Can you get an external disk caddy that you
just slot bare drives in?
I've no doubt you have good reason for wanting all this storage. I just
fail to see why you need huge drives for it if most of the time you're
not doing anything with it.
Get yourself a basic 4-way DAS/JBOD setup, PLAN where you're putting all
this stuff, and plug in and remove drives as required. You don't need
all these huge drives if you think about what you're going to do with it
all. (And while it takes time and hammers the system, I regularly record
off the TV getting a 2GB .ts file, convert it to mp4 - same resolution -
and reduce the size by an order of magnitude - maybe more.
If you've got two hot-swap JBOD enclosures, that's brilliant. You can
stream from your media centre to a drive, swap it out, and use a second
system to then organise your collection.
Oh - and if you are worried about disks going walkabout, just LUKS the
whole disk, and without the key nobody can read it ... build your
partitions or whatever over it.
Cheers,
Wol
