If I purchase this with 4 x 3TB drives, what is the best RAID configuration?

use the Synology setup software and let it configure your raid (in this case it will likely use RAID5) ... if you are in need of extra redundancy due to high data security, switch to the manual setup and use RAID6 ... this configuration will use 2 spare drives and will reduce the amount of disk available significantly (the price to pay for very high data availability)DLLD

Hi, you can to use in Raid SHR or Raid 5. You can go to this website and choose the best Raid for you. http://www.synology.com/support/RAID_calculator.php?lang=us

Generally the SHR (Synology Hybrid RAID) is the best choice, it gives you certain freedoms that make future changes easier. If you want to be more traditional, a RAID5 option is good, both will allow one HDD failure without data-loss. If you are storing very important data, you might want to look at SHR2 or RAID6 which allows two drives to fail without data-loss. Synology have a handy RAID Calculator to view your various options http://www.synology.com/support/RAID_calculator.php?lang=us

The thing is - this device configures RAID automatically so you don't even have to think about it.

Yeah, I fell for it, too. I thought I was getting 2x 4TB drives -- and it is TB, btw...not gb (which is 1000x less). I found it's only 2x 2TB drives. I believe you can change the Raid to 0, though...which will stripe data across both of them and you'll get nearly 4TB of storage. The only downside to this is if one fails, you lose the data on both. Make it more fun then...and add a 2nd one to the network and have them back each other up =)

I'm running 4x1.5TB drives with ZFS RAID-Z and Ubuntu 12.04 LTS on a flash drive with 2x4GB 1333. It's been performing very well, no complaints! I'm just not looking forward to when I have to upgrade those drives, at least they were free.

Yes, It is very conservative when it comes for the disks. My diskstation rejected 2 hard drives of mine that I never suspected. One of those disks died one month later. Anyway the raid config is still the best choice to avoid surprises.

I am running 4 X 2tb hard drives in a "mirror" config. That only gives me 4tb of actual storage space but the hot swap feature was what I wanted.

2 2TB drives. If you want to maximize storage space, choose a different raid configuration.

RAID 0,1 and SHR (Synology Hybrid Raid). With only 2 drives you can't get 5.

I run mine with the bays partially full. 3 is certainly the magic number for RAID5 and Synology's proprietary striping method.

I purchased the 2-drive version, but if the same thing applies to this as other 4-drive NAS's, you'll want to install them at least in pairs (if doing RAID 0 or 1). If you're going to want RAID 5 (and if the 4-drive unit supports it, which I assume it does), you'll want to install all 4 for best results. Edit: The 4-drive NAS's I've used only allow for 2 arrays, so don't plan on having 4 separate single-drive arrays.

You can configure the drive however you like (raid 1 or 0) and it works stand-alone or daisy chained. It's a very flexible and reliable drive.

Yeah, this is a low cost solution. Those Pegasus RAIDs from Promise have the more serious enterprise architecture. This is a basically a box that allows you to have four individual drives hooked up to a SATA controller, and linked to a Thunderbolt port. The default setting is as individual drives, and then you can impose a software RAID on that. I use RAID 0, and I back-up on other drives.

You can configure it as JBOD (just a bunch of drives) and consolidate your various drives. If you configure as RAID, you'll need to replace bad drives with exactly the same size and possibly type of drive

Using X-RAID is the only way to make that work. But you are limited to 1 volume, if you want more than 1 volume you would turn off X-RAID but you cant go back without reformatting your drives. X-RAID will manage your redundancy

Last i read it will suppourt 3 tb drives. Dont know if it will take 4 tb drives.

Minimum RAID 5 configuration is 3 equal disks, I think you can add or replace one and regenerate RAID configuration again, but don't risk your data, since my data is more costly that the 4th disk value, I would prefer to buy max configuration to avoid surprises

I've had problems with Greens on servers/RAID before (not on this machine, though), so I was wary of them and bought a bunch of 4TB Reds that work great so far (about 4 months in).Combined storage spaces over 6TB are no problem - my RAID 5 is just under 12TB total, and you could go much higher with larger drives and a different configuration.

I believe by default they come in a RAID 1, which would give you 2TB of total storage. If you set it to RAID0, you'll get use of all 4TB (probably 3.6 or so useable) but you will not have redundancy.
