Thanks to the generosity of my brother (and his unnerving need to upgrade on a regular basis), I am now the proud owner of a Qnap TS-509 Pro that is fitted with 2GB of DDR II RAM and 5x 2TB drives (8GB storage with redundancy for 1 drive).

Current estimated time to transfer all my data from the old to the new is 17 hours, think I'll go make a cup of tea while it does it's thing

You can never have enough storage (although on your puppy, I'd only end up with 4Tb, for performance reasons). I find the problem is backing it up, esp as I can't afford the latest and greatest tape drives, so stuck with a first gen LTO.

As I'm under 600Gb of data that I *must* be able to recover (photos, docs, source code etc etc), I can just squeeze it in to a weeks worth of backups.

How I long for LTO4 or later to be able to do it all nightly.  //TB goes off and rattles piggy bank, before sulking

Same problem here.
I could drop the array down to 6GB in order to have a 2 drive redundancy, but none of my data is really what you could call "mission critical".
My brother upgraded to the TS-1079 Pro and fitted it with 10x 2TB drives in a RAID 6 config which results in 16TB of storage with a 2 drive redundancy as he had already filled the old one to capacity.

If you're going to use language like this, you need to change your name back to Martian.

I'd be happy with just 1 drive redundancy, but I need mirroring for write speed on my disk subsystem, as some VMs are very intensive on writes, and RAID5 is quite poor (and my controller is too old for ADG/R6)

The Infrant can do a 0+1 array which would give you a 4x read and 2x write speed gain with at least 1 drive redundancy, albeit at this point you would drop to 1.5TB with the disks that are currently fitted.

Not me     I do know that a computer has a screen & a keyboard though

Oh yes . . .  & plugs in the wall

RAID is "Redundant Array of Independent Discs". This system is used for two reasons, redundancy so you can recover data WHEN a hard disc fails and to also increase read and write speeds. Personally I'm surprised that with RAID 1 built into PCs that most people with any critical data (this includes digital photos) aren't at least running RAID1. I run RAID1 on my servers and when I next upgrade my PCs I will be running it on those as well. I like all important stuff to be backed up on several systems as well as a backup HD.

I wish you'd mentioned that before I changed jobs!

Make sure you keep your backups someone distant from your originals.  Like your car boot or even garden shed

You then may also need to encrypt them in case of theft.

That seems quite a lot even to me with 8TB .  I assume it is for HD TV?   Even so I get 800 full length films on 2TB  so 31TB?
