Since this is a RAID equipped device with two drives, does it contain two 4TB drives or two 8TB drives?

Two 4TB drives. You can configure it to mirror those two 4TB, split it so parts if each file could end up on both drives (makes it very fast, but vunerable to corruption if either one fails), or separately to use them as two unique 4 TB drives for a total of 8TB.

You can configure the drive to be either 4 TB or 8 TB. The device itself only contains two 4TB drives.

RAID 1 is mirroring meaning that there will be two 4 TB partitions giving you 4 TB of storage

This something I do not know.. I have 2 x 2TB in mine set up as Raid 1 so they image each other. I also received my first one that was defective, but after using Zyxel's RMA and replacement under warranty, the second one I received is working fine.

it comes with none. The hard drives are sold separately. You can hold up to 12TB using 4 HDs of 3TB each when using linear RAID partition.

Robert,The Certified Servers team appreciates your question. This particular listing comes with (4) 1 TB 7.2K SATA drives.

It does not come with any drives. You have to buy your own.I put in four 3gig drives. I set it up as raid-5, and it has about 8.2 TB.

It comes with two 2TB drives, and can be configured to either RAID1 or RAID0 easily.

That really feels like false advertising - and that is true of all the RAID mirror vendors - not just WD - really gives me a bad taste. If WD are gonna call it a Mirror 4TB then WD should include 2 X 4TB drives and not make us all look for the truth.

2 - 2TB drives. It is RAID1 (mirrored) so you get 2TB usable. If you add a third or forth drives then it converts to RAID5 and cannot be downgraded after the conversion.

For others seeking an answer to this question, the answers aren't entirely correct. Plug it in stock and the answers are correct, you will see 4 drives. But this is meant to be used for a disk array. Google "RAID Types" and you'll get explanations. You can most definitely set it up as a RAID 0 and all your drives will be shown as 1 drive but it "stripes" all your data across all the drives in the RAID with no redundancy and is not recommended due to easy data loss. But you also can most definitely use this as a JBOD and 4 drives show up. On a side note, do not waste money on DrivePool. There are RAID and Partition managers out there that do a way better job for free. For others seeking an answer to this question, the answers aren't entirely correct.

Yes and no, I have two of them (2TB and 4TB), the 2TB is 7200 but the 4TB is 5900. It appears all of them are 7200 except for the 4TB. The models of the actual (internal) drives are ST2000DM001 and ST4000DM000. In case you want to google some more.

Same here: 750GB x 2. They're also not RAID 0, so you don't have one drive with 1.5TB, but rather a 750GB C: drive and a 750GB D: drive.

My guess is it is a two HDD system, correct? If that is the case it is most likely set up as a mirror, raid 0 I believe.hth,Don

Assuming 4TB drives a re supported (may require a firmware upgrade on the RAID controller) then 32TB is correct. If 4TB drives aren't supported by Highpoint (the RAID controller vendor) then the limit is 24TB (8x3TB drives.)

This is a cage for up to six drives. This cage allows you to change a drive quickly (hot swap).Raid is a function of either BIOS(hardware raid) or WINDOWS(software raid). I recommend thatyou GOOGLE "raid" and educate yourself on it.

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.

I'm not sure either. I've only used mine for 1 drive. I doubt it would work for 2 at once. You would probably need 2 adapters and some software that could reconstruct the data, which is shared between the 2 raid 0 drives.
