Can I set the Mobius up for a 3 drive raid 5, then have the other two bays for JBOD, or RAID 1? Home user, not everything needs redundancy.

Yes, if you use software RAID, and not the built-in RAID. Then the box would be set to JBOD ("Just a Bunch Of Disks"), with the software RAID package taking care of the RAID on the specified drives.

Not really. You would have to format the existing drives when you added the new ones. What you're describing *might* be possible if you used the JBOD (just a bunch of disks) configuration, but not for any RAID. For all their RAID configs, you have to choose the number and size of disks at creation, and you can't change it without reformatting.

Can you run RAID that way? Id like to install 2 2TB drives, for large capacity RAID.

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.

This is a question that changes with time. As of the date I write this, the Mobius has been tested to 6TB/bay, and I am successfully using a 6TB drive myself. They say they are preparing to test 8TB drives, but until tested they won't say for sure that it will support it. Interestingly, the SATA standard actually supports 48-bit Logical Block Addressing (LBA), which allows for disks up to 144 PETAbytes (144,000 TB!) in size. So, as long as each manufacturer holds to that standard, you should effectively be able to put ANY size drive in the enclosure far into the future. However, only 6TB/bay has been tested as of the date I write this.

If you want to utilize hyperduo (ssd drives combined with hdd) you need to use the proprietary software or the software from Marvell for this specific raid controller. if you are not mixing drive types/capacity, and want to utilize software raid, I don't see why you couldn't don't use another raid software. The four drives will show up as separate so there shouldn't be any problems. However, hardware raid is usually preferred for better results.

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

It depends on the type of raid setup you use. There is a hybrid setup that makes use of all the drives and maximizes the space available. This way you can have different size drives. I accepted this as the default. I can't verify how it works though as all my drives are the same size. It's a bit slower than I would have liked also, but hey, it does the job.

No. This card has no RAID functionality. You need to find a card that offers RAID 1, which is drive mirroring, to do what you're looking to do.

If you are asking if you can set up two independent 4 drive Raid arrays the answer is yes. Whether or not the single Raid array can serve as a "hot" standby for the other I don't know but I would doubt it.

You have to add at least one drive in order for the unit to work. My unit is running on 4 drives of 2TB each for a total of 8TB. I run in raid 5 which allows all drives to be mirrors of each other. If one drive fails for any reason you can simply replace it with another drive and all of your data will automatically copy from one to the other. As a minimum you need three drives to run raid 5 but like I said, I'm running 4 drives. When you start up the unit it walks you through everything you want to do with it. It is very user friendly. Hope this helps.

No. Once you do the initial setup, if you add a second drive you can not set it up to run in Raid 1 without having to format the drive.

No, RAIDS do not work this way, you cannot change between types on the fly. however, XRAID, which this model offers would give you redundancy and is expandable (can't remember if this can be done with 2 drives though).

No. If you use Synology Hybrid RAID, you can expand with the same or larger drives. With 5 bays, there are numerous expansion options and multiple volume options. There is a lis of options on Synology's website support.

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

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.

It's either/or. When you set the drive up you have the choice of using the RAID 1 or 0 configuration. If you decide to change your mind later, you'll end up losing everything you've stored on the drive. I stuck with the RAID 1 config to provide redundancy, even though it cut the capacity by half.
