Specs say 4 drive trays and RAID5 ... can it be conf'd with a 3 drive RAID5 and 1 hot spare?

This unit does not support hot swap. But has served me well in afghanistan.

I am not sure about the hot spare but it can be configured with RAID5 using 3 drives.

I added five drives and I had no problem. I did make sure that the drives I added were the same size as the existing drives in the NAS

Yes, you can have any number of hard drives installed (from 1 to 5), you will be limited to certain Raid configurations depending on the number of drives installed. Synology website is very useful in helping to determine the proper configuration.

Don't have exactly such an experience, but this is one among not many (if not the only!) capable to connect multi-drive bays with spawned (e)SATA. Have connected self-made 5 drives bay, worked fine.However, i would advice you to ask Drobo's tech support regarding tech specs requirement and if their boxes either provide multi-drive (spawned SATA), or single logical RAID-drive on eSATA port.

Based on the Synology RAID calculator you should have 12TB of usable space and 6TB of parity (http://www.synology.com/en-us/support/RAID_calculator)Adding 3 x 3TB drives would give you 18TB of usable space and 6TB of parity

I have eight 4TB drives, totaling to 32 TB's. Haven't tried 5TB drives.Do note that I'm no longer using the included RAID controller though, it had too many issues. I opted for the SANS DIGITAL HA-DAT-4ESPCIE PCI-Express x8 SATA II (3.0Gb/s) Controller Card on Newegg, had no issues with it since.I think the bus supports 64-bit address mapping, so the capacity limitation per drive is most likely a limitation of the controller and not the multiplier that's built into the SAN enclosure.

I started with one 2TB and have been running it for several months. Adding a second of another brand and size. It's flexible to do that. You can even put in 2.5's with a converter tray, or some people mix in SSD's as well. Pretty limitless. AND most use cases are hot swappable, meaning you can pull and add drives while running.

Yeah, most likely. I've used a variety of drives since I've owned it, some listed as "supported" and others not. All have worked fine. The only thing I'd recommend doing is checking the Synology Raid Calc to make sure you get it set up with the specific RAID you want to maximize space: https://www.synology.com/en-us/support/RAID_calculator

There are 4 quick removal and you can use the top 5.25 bay with an adaptor to give you 5 total. I'm running 2TB drives for my NAS, so I can't speak to bigger drives. I would suggest low power drives if you run 5 drives for thermal reasons.

http://www.synology.com/en-global/support/RAID_calculatorYour best bet to go look here and see what kind of configs work.

Yes, as I have three sets of SSD in raid 0 with three OS. The only thing is that the cables are not that long.

This device will neither allow or disallow that. This converter will merely allow you to mount 2 drives in one bay. If your motherboard has RAID capabilities then yes, you can configure 2 drives as one.

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.

Although I am using two 1TB drives in RAID 1 mode, the manual says "2 x 2.5" SATA HDD, total capacity up to 6TB".

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.

There won't be enough room for two 3.5" drives, but, if you buy a dual 2.5" drive to 3.5" bay adapter, you can mount two drives. You also can mount one 3.5" drive and tape up to two 2.5" solid-state drives near the front of the chassis (with no moving parts, they don't need to be secured as well), and there are plenty of SATA connectors onboard. Note that the only cooling fan is a very small one on the power supply unit, so I'd recommend going with solid-state drives anyway if heat concerns you. I'm very happy with this purchase, and I use no PCI card, just the onboard video, onboard network, onboard management interface, onboard SATA controller, and software RAID.
