This is one segment where build-your-own is still *way* cheaper than any of these crazy setups:
Intel Pentium G620T: $83
Intel DB65AL: $85
8GB DDR3: $50
Hyper 212+ with fans removed: $20
Fractal Design Mini: $100
Corsair CX430: $40
FreeBSD: $0
Total without disks: $378
5 * Hitachi 5k3000: $700
Stick the disks in a raid-z, and wham bam, there's $1078 for 12TB of RAIDed NAS.

You don't have a hot plug enclosure in there and much all of these will hot plug drives.

You're technically correct (the best kind of correct). But... While I agree a hot plug bay may be a nice idea, really, on a home NAS, what do you want to hot plug all the drives for? If you're trying to fail a drive and rebuild the array you probably aren't in a position where you want to be using it continuously through the rebuild.
What's the use case for hot plugging the drives?
bygmack ( 197796 ) writes:
And yes I have used a cheap dual drive NAS while it was rebuilding the array. It was slower but still functional.
Hot swap cases make drive management much easier. Drive 3 of 5 needs replacing? Forget tracing cables back to the motherboard just pop out drive 3 in the array and replace it. This also means I can get someone else to do it even if it means walking them through it over the phone.
These things need to be dead easy since I have been going out of my way to tell all of my non techie friends that U

Don't know how that first "And" got there even though I went out of my way to proofread that.

I use drive bays in my unRAID. While not hot swappable there's no cable tracing to be done and it's WAAAAY cheaper than the crap these companies sell as "NAS".

Go look at the case involved now. The thing mounts hard drives in clip around sleds, there's not a single screw needed undoing when you want to swap a drive. Shut down, slide case door off, slide drive out, slide new drive in, boot. Yes, it involves shutting down, and yes, this is a shortcoming, but seriously, what home NAS needs 100.00% uptime?

True. Which is why, most home NAS servers shouldn't user RAID. RAID only gives you uptime (in addition to speed, but we are not discussing that, I guess).
Data security is much better in home NAS by file duplication in different disks. More flexible - really important files can reside on 4 hard disks, less important files can reside on only 2. RAID Write hole is also much more applicable to home NAS, which causes RAID to be riskier than JBOD. The chances of "rm -rf" , and data corruption are also higher here
bybeelsebob ( 529313 ) writes:
What RAID write hole? Remember, this setup involves a RAID-z, which uses copy on write semantics, and hence has no write hole.
bybingoUV ( 1066850 ) writes:
Yes, the write hole statement only applies to lower level RAID. Still, since other reasons stand, RAID (even RAID-z) is an overkill for most home NAS devices.
