Can I have multiple arrays? e.g.: 3 drives in RAID-5 and 2 in JBOD?
619202
Yes; up to 1024 volumes with some DiskStations. Best to download the manual for the specifics of a given model before buying though.

Yes. As long as you have the correct number of drives for the RAID type, you can have as many as you want.

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.

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.

The drives can be different sizes, but if you want the redundancy of the Raid architecture they should be the same size. You can run them as standalone non-raid drives and then they can be different sizes. SATA drives are required.

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 think you want a RAID array, that is a number of hard disks linked together with a total capacity approximately equal to all the drives summed up (depending on RAID type in use). The latter is not a recommended RAID configuration (if one drive fails, whole thing goes down) and can be complex to set up. Short answer: Maybe, but better not, just get a newer higher capacity hard drive for the same price or lower later on down the line :)

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.

Yes Type JBOD is one or more drive not in a RAID manage as separate drive Or Also Spanning Combination of all drive into one logical volume I use Raid 5 with WD red hard drive work great with 4 drives

Yes. Configuring the drives as RAID0 or JBOD will give you combined size of all drives with no redundancy presented to Windows as a single logical drive.

With the Synology RAID option you can start with the 3TB drives and add larger ones later. You just can't anything of smaller size than the drives used to create the array.

If its set up as JBOD then no, it will string drives of similar style but different sizes together. If you are striping or mirroring the data as in a RAID, then it will only use the smallest GB size of the drives in the set. That is the RAID standard and if WD is adhering to that standard, that would be how it would work. They have pretty good pre-sales if you were to ask.

I put 5 each 3tb WD Red drives in my Thecus and set up a RAID 6. I think you can use any number of drives of any size. Just keep in mind that if you use RAID it will only be a percentage of the smallest drive in the array.

Yes. The default raid setup will need to be disabled but it's not a problem. I have 2 drives raid 1 and another 2 drives raid 0. You can create a volume on a single drive too.

This card doesn't actually do RAID (it's all done in software) so there is not really any restriction in how you can use it. For instance I used mine with 4 drives connected to this card and another to the on-board controller, for a total of 5 drives in the array.

Regarding use of multiple sized drives; you should not only use the same size, but the same brand and model if possible to avoid issues. The only configuration that this doesn't apply/mean as much to could be JBOD (Basically just one big data dump w/no redundancy). Data gone is gone:)

You can add drives as you need them. The drives can be of mixed sizes too for the hybrid raid configuation; however, I recommend you try to keep to one drive size so select your initial drives with the thought of expanding later.

RAID requires multiple drives. RAID stands for (Redundant Arrays of Inexpensive Disks). Redundancy is it's primary function. This could be used to create one but only as a component. You also need a RAID controller either in hardware or in software (sometimes in the OS). This device can fit only 2.5"drives, of which it will hold six. I don't think you have the expertise to build one on your own. Read about RAID on Wikipedia and the other answers.
