Behind you... Naked!
My Fileserving setup is in deed of a refurb.

I accepot that what I want may be over my limit, but I am going to ask all teh same... Needs ( or rather greed ) may just push the vote ...

I am after a NAS, that will let me have 4 HDs. RAID 0 + 1

I need to have it HOTSWAPPABLE and SELF REPAIRING, plus, I also need to have the ability to increase the Disk size.

For example, lets say I start with 4x2TB With Mirroring, it will give me 4TB ( Ok, well, 3.7 or so, you know what I mean ), but lets just say that, out of the 4 disks, Disk 2 fails in some way... A Light will come on, showing me that Disk 2 is in error, so I want to be able to simply, yank that disk out, and plop in a new one. The RAID setup will then automatically rebuild the array for me.

I can then either throw the original disk away, or if its only got a bad sector or two, use it somewhere else!

I also need to perhaps, if as I said, I am using 4x2TB Drives, and I wanted to take them up to 3TB Drives, then I could simply by swapping them over one by one, and then rebuilding the array each time... ( I could in theory swap them 2 at a time surely )

Anyway, does such a device exist?
I see no reason that such a setup can be made up with relative ease, and indeed, I have done this in testing on some old Disks with more of less good ish results, but I want it in a NAS box where I need to put ZERO effort into it.

Anyone?
 
Synology

Is just use the SHR (hybrid raid) and keep manual backups externally.

Remember, raid isn't a backup, it's just redundancy.

Buy big drives from the off, Western Digital Red. 2x 6tb drives would be a good start, then just add 6tb drives as you run out of space. Having two to start off with would be raid 1. Adding the 3rd, the SHR would turn it into raid5.

I've got the DS414, great piece of kit, super low power consumption, awesome gui.
 
Like Bledd says, Synology NAS would be great or failing that a HP microserver running Xpenology but you won't have hot swap with that.
 
Yes, definitely WD RED. Im ashamed that I dont have right now to be honest, but there you go. Do they do 6TB in the REDs? I was looking at the 4TB TBH.

Yes, I am aware about the basics of RAID. I was more considering the MIRRORED aspect being a bit of safety against failures but STRIPING for the SIZE.

That said, HDs are very quickly getting bigger ll the time, its only a matter of hours before 8TB is out, and then...

Sheesh... Cheers for the link...A niuce range, one is bound to be about right for me... I will check them out shortly.

HP Microserver?
I suppose using a PC as a file server again like I used to is a much cheaper option. after all, I do already have the hardware.

The idea, I will admit, was more of the "I am very lazy and dont want to do a thing" kind of idea, and having to actually do work, was really what I did want to avoid.
I know its simply not possible to put in ZERO effort, but the least effort is the goal.

I will have a look at these synology things... Certainly, a quick peek showed a good few there, so I will have a proper think, and if nothing seems to ring my bell, I may go back to a PC File Server.

Many thanks guys. Very much appreciated.
 
+1 for Synology.

You don't need RAID 0+1 for home (RAID 1+0 is actually better). It needs a minimum of 4 discs and you lose 50% of the capacity. Just use a Synology and use SHR as stated above and you're good to go.
 
Synology is more expensive, but it 'just works'

Don't rely on any RAID as a 'backup'. It's not a backup. Just protects against disk failure. You should have another backup alongside it. (ie keep an external disk with your important data on too).

The DS414J is a well priced model.
