Is it possible to hot swap in and out a third drive on some regular schedule for off site storage? Would RAID 1 bring a swapped in drive up to date?

I would strongly advise Against swapping the drives out for a DR purpose, as there is NO guarantee that you would be able to re-build the RAID on the system in the event that you lose both drives. You would be better keeping the drives singular out of RAID for that purpose, unless you are fully bringing down / rebuilding a RAID each time you swap the drives.. which gets costly / time consuming.

Yes and yes. That is what the usb (USM) drive slot is for in the front of the case- to do just that with an external drive without having to open up the case...

If I go by all the documentation that I read according to the manufacture, this is possible, with that said, I do not have a lot of faith in the way these seat in the device itself and so I would probably not do it. The stability just isn't there unless you have an absolute need to store off-site data, in which case I would consider it safer to do a robo-copy (If you are using Windows)... and a second drive. As a matter of fact I would try the UMC solution they offer on the front of the device to accomplish this.... if you need more help in how to do this feel free to e-mail me at sicameron32@gmail.com If I go by all the documentation that I read according to the manufacture, this is possible, with that said, I do not have a lot of faith in the way these seat in the device itself and so I would probably not do it.

Using 5 drives without redundancy is just asking for problems... I would venture to say that one of those drives is going to fail within a year. I have a 2x 2GB RAID1 system for the past 4 years, and had to re-sync them once. In the last 15 years I've had ~5 drives crash or get corrupted. Never again will I leave valuable data in only one drive.

There would be no reason to re-install the DSM OS when changing RAID types. However you would lose all of the data on the RAID array when you switched.

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.

Don't know about SATA 3, but config is done the same as any other RAID controller, you hit CTL S or whatever it wants and create a new raid with the drives you have plugged in to it. Worked fine for me with 2 SATA 500G drives.

The documentation is a bit unclear on this. In one place it says to use the same size drive, but in the "Replacing a Drive" section is says that you should use the same size or larger, but the extra capacity would be unused. Assuming you are using RAID1 then you should use the same size drives. The drives are SATA interface. I used two identical (same manufacturer, model and probably the same lot) 2TB drives in my configuration.

I backup critical files to an external 3TB HDD plugged into the unit and have a remote DS212 at my in-laws house with 3TB RAID 1. The remaining 7TB is data I could recreate, but it would be more painful. Just going with RAID 5 and no other backups is a poor decision, especially if you are a business.

Update-I did have to put in 5 old, dummy drives to setup the Raid 5 on the new box & then put in my 5 drives, in order of course, & the Raid came right back up. I just happened to have 5 old drives to use. Otherwise, I don't think you can do it any other way.

I asked Oyen Digital Tech Support this question (they are very responsive). This was their reply: "If a 3-drive RAID 5 set is created, and a 4th drive is added later, it will be a hot-spare drive. The Mobius does not have the ability to add the 4th drive to the original 3-drive set. The only way to accomplish this is to clear the original RAID and recreate a new 4-drive RAID 5 set." Back to me. Another option is to use software RAID. You would put the enclosure in JBOD ("Just a bunch of Disks") mode, and create your 3-drive RAID set with the software. Then when you add a 4th or a 5th drive it will either be treated as an independent drive, or can be part of yet another RAID set.

Yes, you can use with a single drive or multiple drives. They do not have to be in a RAID configuration. That is optional.

Depends on the configuration... If you don't change the RAID setup, it should be faster than a single 4 TB drive because it distributes the writing and reading across the two drives.

I set mine up with one other one in a RAID 1 configuration and it works great and has for several years now. Not sure if it works for one RAID configuration it will work for any RAID configuration, but probably.

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.

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 =)

sorry for my first reply, hit the wrong key. it has included the hard disks, you will find it also without it so you can chose the hd size you want in it. i do not know if can be used in raid 1 or 5, sorry.

Either is possible, it has two drives in it and can be used as Raid 1 or you can use them as Raid 0. From recollection it comes preconfigured to be used as Raid 0 - taking more advantage of the the thunderbolt interface.

I believe once you change to flex-raid you can setup the drives however you would like. If you have 4 drives you can use raid 1 for two drive and leave the others drives as raid 0
