Can you explain what aspect of deployment you are referring? Is it sticking the disks in and making sure the disks you chose works or adding users, creating share, adding to your domain controller, etc? This would be more accurate with the word "usually".Pre-built vs DIY NAS :
Pre-built is faster to deploy
The same can be applied to a custom build system. The OS can be setup to automatic update if you so choose.Pre-built is mainly maintenance-free (automatic updates of services and firmware)
Always have less features.Pre-built has sometime less features than DIY: Debian or Red Hat has a lot more packages you can install.
The one you almost got right. Why only ZFS can make use of good hardware?Pre-built has lower end hardware (mainly Atom) while you can get better hardware when building a custom NAS (but can be useless, unless you go with ZFS)
Again, better with the word "usually". One could also build a low power system.Pre-built uses less power (because it has less powerful hardware)
Can you explain how a pre-built Atom system (as per item 4 above) will have the same performance calculating RAID6 parity as a current Xeon or i7 processor? Have you even heard of dm-crypt or true-crypt?Performance are about the same since you are limited by Gigabit Ethernet.
Not all pre-built uses EXT4. Another place for the word "usually". And they usually run on Linux md RAID. And why do you think all custom build NAS uses ZFS. This is only one of the many many filesystems available. You should skim through the 10+TB thread for the various setup and some of the filesystems available.The BIG difference : Pre-built uses EXT4 file system, while you can uuse ZFS (OpenIndianna, Solaris, FreeNAS, etc) with a custom one. But ZFS is mainly used in larger scale storage solution.
well after posting some questions on company sites I am a bit put off with them.
I was wanting to use individual drives mainly for storing backups and movies.
But all of them roll the JBOD into a single drive. I asked why then even have it, I would just go raid0
I got some pretty sorry ass answers to that one.

ZFS is a capable filesystem, but saying is is the best is like saying one screwdriver is the best screwdriver. I did my research as well and decided against ZFS because of some of its restriction that would not fit my requirement.Lol
Nah I haven't been brainwashed.
I've made my own research about ZFS and that's the conclusion I've ended with.
ZFS is a very nice file system with great features, but generally require more power, especially from RAM. But some have successfully installed ZFS systems on little HP N5xL and got good performance out of it after upgrading RAM.
Finally, all I can say is that both pre-built and custom-built NAS have their advantages and disadvantages.

I asked some more and it turns out that none of the modern nas can support more than one virtual drive.
As I've studied from ZFS, this file system requires more power than any other file system. It must have a lot of ECC RAM, so it implies a Xeon CPU and SSD for read/write caching.
Ghost26,
Ok. Now I get it. You clearly have been brainwashed by the ZFS camp. You need to lift your head up from your dogma and look around for a minute.

andI'm interested in the reasons that pushed you to go against ZFS
When I started building my NAS ZFS was not supported under Linux.
I'm currently writing an essay (I'm a student) on networking storage and this could be interesting. I have to write down every pros and cons of systems, including ZFS.
I guess I am going to go raid5.
I asked thecus and synology and both went bonkers when I said I want to use individual drives.
Then when I said well single lumped JBOD does not make since, I would go raid0. They talked down to me saying they didn't understand, IF raid0 one drive goes down then you loose all of it, BUT with jbod combined the only time you will have NO data to restore would be if the os drive crashes. WHAT?
They liked to say concatenation is the best way. wow a big word that makes more since now
They could not understand why anyone would want independent drives. I really pissed off the synology people when I said how about 2 raid 1's.
LOL
I asked some more and it turns out that none of the modern nas can support more than one virtual drive. So something like the old nas you could have individual drives something like 192.168.50.1 192.168.50.2 etc
the new ones can only support 1 address
is that the Synology Adaptive raid you are talking about.
They say it will use 100% of mismatched drive sizes as well.
how good it this?
I looked up the 412+ and its one of the fastest nas.
Funny that they released a 413 and now coming out with a 414 and both are slower...maybe I don't understand numbering lol
