Will this operate in a JBOD mode (no raid)?

The internal RAID controller supports RAID 0, 1, 3, 5, 10, and JBOD (Non-RAID, or "Just a Bunch of Disks"). RAID configuration is accomplished through a dip-switch on the rear of the unit or through a GUI supported by Mac, Linux or PC.

Yes absolutely, I have one set this way with a 3gb, 2gb, and 1 gig for a total of 6 gb.

All switches are down for clear RAID, or JBOD ("Just a Bunch Of Disks"). That should be how the enclosure arrives. If the disks you are installing were not previously part of a RAID, then your original data will remain intact.

that's not true, note I had to update the firmware to get that option of Non RAID. But i cant remember if it was the firmware vision it came with or not. But the firmware was available on the product site

I've been using consumer class drives with this for several months now, no issues. I have it set to plain JBOD mode, and then run ZFS on top of that.

Unfortunately no. It only has e-Sata connections on the back. So you have to run it through the raid controller card.

yes. You would use disk utility in Mac OS. Thats how set mine up. Using RAID 0 and RAID 1.

No, this isn't a RAID (although there is a version of this that does support RAID). I bought it as a replacement for a couple of hard drive docks that were giving me trouble and it worked perfectly and other than Windows having to re-recognize the drives Windows never even made a blip.

Yes, you can configure the RAID management software to send an email in case of some kind of event. Also the controller emits a steady beep noise in case of RAID failure (I did have a drive fail on me) so if you're anywhere in the vicinity of the server, you'll know!

I don't know the maximum. I'm just using it for JBOD and not RAID. I needed more SATA ports.

There is no RAID inside this adapter. Some system boards have 'fake' RAID, but you have to go waaay back to get IDE RAID, now it's mostly SATA. Unlikely but possible to still find a card that does IDE RAID, PROMISE made some. As far as I know, the 'drives' (microSDs) enumerate as 0 and 1, a and b etc. to systems. No striping or mirroring going on without outside help. The slow and wear-prone media of most microSD just doesn't make good RAID sense anyway.

No.Raid Mode Support Raid 0 (Spanning) JBOD Raid 0 (Stripping) Raid 1 (Mirroring) Raid 3 (Stripped set with dedicated parity) Raid 5 (Striped set with distributed parity) Raid 10 (Mirroring + Striping) Raid 50http://www.mediasonicstore.com/servlet/the-24/Mediasonic-ProRaid-8-Bay/Detail

No, it cannot be a JBOD. It forces at least 1 disk to be a data redundant disk. No, any data on the disk will be wiped after putting it into the Drobo as the device formats it with its own filesystem. When you put the disk into the Drobo, it will almost immediately begin formatting it if it isn't one of the drobo's disks.

Yes, running it now in conjunction with the 2720 card to drive 12 SATA hard drives using Stablebit software JBOD. At one time I used the software JBOD on the 2720 while using RocketRaid's hardware bios on the 640L as a RAID 5 array. Worked fine, but too complicated.

Yes, I'm using it for the same reason (add extra sata ports). You can disable the raid.

JBOD or even a mix of different RAID arrays (i.e. a 2 drive RAID1 and a 3 drive RAID5) is possible.

Short answer, No, due to port expansion eSATA. Longer answer, you wouldn't want to if you could, with double (or worse) data traveling on a single wire, performance would be poor, and it would burn up from constant multi-drive activity (which is the likely reason that the RAID version of this was discontinued)

Yes, It is very conservative when it comes for the disks. My diskstation rejected 2 hard drives of mine that I never suspected. One of those disks died one month later. Anyway the raid config is still the best choice to avoid surprises.
