If I buy one with pre-loaded disks, is it RAID configured? If so, which one? I want it in RAID 10 (16TB).

Quick note. I bought one new from amazon and it did not come preconfigured RAID 5. I had to select it from the interface. I'm glad I checked before migrating my files to the drive. Other than that, it's been great.

I have the 16TB version. The information included with it states: "Out of the box, the four-drive version of WD My Cloud EX4 is configured for RAID 5. For the zero-drive unit, no RAID mode is configured if you install drives but don't run the setup software. However, if you install drives and run the setup software, your unit will be configured with the following storage modes: 1 drive: JBOD. 2 drives: RAID 1. 3 drives: RAID 5. 4 drives: RAID 5." Also, "The WD My Cloud EX4 device provides the following storage modes: JBOD: The use of one or more drives not in a RAID configuration but managed as separate logical volumes. Spanning: Drives are combined in a linear fashion to create one large logical volume. RAID 0: Data is split (striped) into blocks that are written across all drives. RAID 1: All data is duplicated (mirrored) from one drive to a second one in the drive group. It provides complete data redundancy but doubles the required storage capacity. RAID 5: This mode provides data redundancy, high read rates, and good performance in most environments. It also provides redundancy with the lowest loss of capacity. RAID 5 is best suited for scenarios where a lot of small input/output (I/O) transactions are performed simultaneously. It requires at least three disks. RAID 10: This mode is a combination of RAID 0 and RAID 1. RAID 10 breaks up data into smaller blocks and mirrors the blocks to each RAID 1 drive group. The first RAID 1 drive in each group then duplicates its data to the second drive. RAID 10 is best used with data storage that needs 100 percent redundancy of mirrored drive groups and that needs the enhanced I/O performance of RAID 0."

I have Sata II WD Black drives in mine. However I would suggest a different Raid bay. This one has its own raid card and it works intermittently. There is a lack of support for the card and its very cumbersome.

It did not work for me as well after first try, although I did not try hard. I decided, it is simply do not worth to spend time trying to make it work. I bought a new 2TB new SATA-6 drive for $85 and decided do not use internal RAID at all. I have RAID on external NAS with all data and cloned internal drive with all programs.

That's exactly what I'm doing and why I bought this; however I am certainly no hardware guru. It takes a while for it to show upon explorer (4-5 secs), windows needs to read it, etc. I would go to the internet and find a forum that has a topic for hardware, giving them the model, intent, etc. Let me know what you find out. I am interested. My final goal it to set up a RAID, still need one more hard drive.

i have run dual raid 0 i have raid 10 and raid 1 i have not tryed dual raid 1 but it shold work fine

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 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.

yes, I have two of these boxes, & I set them to either raid 0 or leave it at the default which is JBOD. Currently, I buy a lot of Seagate Barracuda 4 terabyte drives, and swap them in and out of these boxes per my various jobs. I work off of the one box that I have at 16 terabytes raid 0, & I back up to the JBOD single drives. it all works fine, & I configure everything using Disk Utility.

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.

depend on yore RAID, can be done using JBOD if you use RAID0 to RAID5 every drive/s you add will have to be its own RAID

I agree with David, you can set it to Raid 0 for full storage space use. I prefer using Raid 1 for protection even though you drop the usable space in half. I like having my data replicated in case of failure.

Yes the software allows different configurations of RAID or independent configurations. I current have 2 4tb velo drives and they are configured as two individual drives. This is accomplished by selecting flex-Raid and not X- Raid during the setup process.

Honest opinion as much as this may suck to hear, take the hot swap out. Mine was faulty and from reviews I've seen I'm far from the only one it happened too. A hot swap would a been nice but I had error after error on my raid and soon as I took it out no more errors.

I use Raid 1, but I think they have raid 0 as well. By default they use an automatic mode called Synology Hybrid Raid that handles raid levels for you, that what I have and I have configured and so far I have seen no problems. Written in Panama City, Panama, on May 26 2013.

I am about to install a 6TB drive so I will let you know if I am successful but according to intel, it should be fine. The support of your HDD depends on the RAID card. This is a RAID expander and is only meant to extend an existing RAID controllers capacity of HDDs. This does not create a RAID array.UPDATE: I have installed my 6TB WD Red HDD and have no issues. Simply plugged it in, turned on my server, and it showed up in my OS (Linux Mint 17.1) without any issues. No configuration needed. Just plug and play.

You probably mean RAID 0 because RAID 1 is mirroring. I had it configured as RAID 10, it worked for a while until it failed but not because it was part RAID configuration.
