I thought I'd throw in a pitch for building your own NAS using an old PC, and FreeNAS (or it's successor, NAS4Free). They are the only NAS software built on FreeBSD which allows you to use the ZFS filesystem (you can also use native FreeBSD to get ZFS, but you's better be a Unix command line wizard). ZFS is a very reliable file system, it maintain checksums on each bit. Most other filesystems just verify the data they are writing to the disk, but do not know if the data on the disk has become corrupted.

My NAS is an older Athlon II 3Ghz system with 8GB RAM, and using six 4GB drives. I boot NAS4Free from a Compact Flash card attached to a CF reader on an add-in PCIExpress SATA card, this leaves all six SATA ports on the board available for data drives. The drives are configured in two sets of three mirrored drives, all in one ZFS volume, so I have the capability of losing at least two drives without losing data. I use the most reliable drives I can find, at the moment according to Backblaze's data are Hitachi (HGST) drives. The NAS easily handles 100MB/sec transfers over Gigabit Ethernet, with the CPU utilization never exceeding 25%. The only problem with any roll your own NAS (and low end commercial NAS's as well) is they use non-ECC RAM, so you could potentially corrupt your data as it is cached in memory while copying it. This is pretty rare, but the bigger files get and the more data you have, the greater the risk of corruption. The only solution is to buy server grade hardware that will support ECC (Error Correcting Code) RAM, which can correct a single erroneous bit in a computer word with error correction circuitry. This is usually expensive stuff, but AsRock now makes some good high end workstation boards for about $200 that can use ECC memory, and ECC is a lot easier and cheaper to buy these days.

Having said all that, I work with computers for a living, most people will just buy an off the shelf two drive NAS and be done with it. Not a bad option at all, just make sure you set up the drives for mirroring so you will not lose data if a drive fails.

OK, it is time for a serious reality check on my end.  I have a 20TB NAS (5 x 4TB) running in RAID 6 and I am out of space.  (I wont go into how many external drives I have) 

While I love the GUI and convenience of the QNAP it is really obvious that I need something much larger, possibly rackmounted.  I am open-minded to ZFS FreeNAS and have the ability to make it happen.

Anyone have any tips on cases?  I'm thinking 12 bays or more at this point.

I recently started transferring large portions of my critical data (masters, photos, financial data) to cloud storage, namely French hosting company OVH. They're offering 1 GB of object storage for 0.01 EUR/month at 100% file durability (this means they pretty much guarantee never to lose any data). Transfer bandwidth of the data from them back to you costs extra. I have set up regular jobs that backup data from my NAS to the cloud.

However, be aware that object storage is not something like your regular network-mounted file system. In fact, it's no file system at all. Files are transferred using a HTTP REST protocol and you need special programs for that.

I'd never use such a service exclusively, but I find this to be a convenient method for cheap off-site backups.

Here's a reality check: do you need all that data on spinning drives all the time?

I burn things to plastic (currently BD-R single layer) for static backup. I use two different brands and burn doubles.

OK, it is time for a serious reality check on my end.  I have a 20TB NAS (5 x 4TB) running in RAID 6 and I am out of space.

This is everything, masters, music festival archives, photos, PC backup jobs, movies, everything.  Not only do I need access it but clients, etc. 

I do have some secure online backup but mostly to the tune of about 1TB that I use regularly, mostly for sharing masters.  As I move to recording more from 4 track 24/96 to 6 or 8 track 24/96 the demand of space for masters will increase substantially.

Morst, I am not a fan of optical discs at all.  While I know that hdd's fail as well it is easier to run RAID and then duplicate/triplicate.  Drives can be swapped and rebuilt.  I cannot rebuild a delaminated optical disc.  I've seen the bubbles and will probably have a dream about them now.  I stored on CDR and DVDR sucessfully (for the most part) and would like to move away from that direction.

After doing about an hour of reading I am thinking that a rackmounted solution may be over my head to build DIY.

What about an expansion bay like the UX-500P?

Unfortunately, my TS-569L is not supported by the expansion modules.

So it's more a question of availability, than simply storage, as such...
