Just let me get better of this freaking flew that got me during Christmas, so that I can get back to work. I can send you a photo of a tray with a hard drive installed.

I haven't tried to hunt down the info on the actual size of the drive sleds yet. Yeah, it will be a tight fit but one of the adapters that fits verticaly against the back of the drive might fit.

I don't know if there's enough space for them, after installing a drive on a bay there's not much room left. Keep in mind the space the SATA->ATA converters will take in each bay.

I found a troubleshooting PDF online somewhere that said the 2.199 TB limit was per array. Promise did reply to me but if I hadn't found that their answer wouldn't have helped much; not too clear. I'd thought about doing two 4x 750 GB RAID 5s. That'd be 2.25 TB for each either dropped to 2.199 TB before formatting or they'd be below the limit after formatting anyway. But 750 GB ATA drives are now ridiculously priced. Add adapters to SATA disks and your at the price of a 1 TB SATA. Use 1 TB SATA plus adapters and you can bet 3x 1TB RAID5 (2 TB), 3x 1 TB RAID5 (2 TB), and 2x 1 TB RAID1 (1 TB) but that's less space for more money. Now I'm considering buying one of these or some similar external array (old ATA-> SCSI boxes are more common with HW RAID controllers than without, and cheaper then newer SATA->SCSI), putting it in JBOD mode, and trying to use software RAID. I'm not concerned with speed. I just want something on the order of 8x 1TB RAID 5 (7 TB) or w/ hot spare (6 TB) that doesn't require me to build an entirely new PC with more drive bays. Thanks again.

I still didn't hit any maximum volume size barrier, but I still didn't get to the 2.199 TB. Try to obtain a reply from Promise before buying, it's safer.

What's the total size of the array(s) you've got now? The manual says there's an upper limit of 2.199 TB on total size of all arrays in the unit. I'm wondering if a firmware upgrade might raise this - no reply from Promise yet. Hey, I’m thinking about buying one of these. What’s the total size of the array(s) you’ve got now?
