Oyen Digital Mobius 5-Bay FireWire 800, eSATA, USB 3.0 Raid Hard Drive Enclosure,Black

This thing is an awesome beast. It is well-engineered and appears extremely well made. It took about 3 minutes to install the drives and set up a hardware raid. Was transferring (backup) files by minute 5.I have this and the Mediasonic 4-bay RAIDPRO. Both are good, but the 5th bay in this allows you to leverage your storage through hardware RAID 5 or 10. Time will tell on durability (most critical) and performance (close second), but so far count me impressed.I haven't formally clocked fair read-write speeds yet because my NAS is splitting resources with building a new software RAID 10, but it seems to really fly. It's a shame my primary purpose is to back up my NAS(es).EDIT (April 5, 2017): I now own three of these Mobius 5 bay units using two in a RAID 5 arrays (5x4 TB) and one in single mode (5 independent 8TB drives) for spot backups for my QNAP NAS(es). All three have performed perfectly every time in different roles. I've grown to like this Mobius 5 bay significantly more than the Mediasonic Proraid 4 bay, which works fine but is pretty flimsy. The easy tool free mounting + sturdy build gives a significant edge to the Mobius over the mediasonic in my opinion. The price difference is about $80 higher, but well worth it. Would upgrade to 6 stars if I could.EDIT (9/30/2017):All three I own are still functioning well connected via USB 3 to both Ubuntu and Windows 10 devices (formatted in NTFS and EXT4). The fans remain quiet and the device keeps the drives cool. The product continues to greatly exceed expectations.EDIT (1/26/2018):All three units I own are still performing well in RAID 5 and 5 individual drives modes. It remains an extremely reliable device.Edit (1/7/2019): All 3 devices I own are still performing very well under heavy use.Edit (5/20/2019): All 3 devices still operating flawlessly.Edit (7/4/2020): All 3 devices still operating flawlessly.

Update: After owning this for a while I'm very annoyed by the sleep behavior. Even if you tell your computer not to put the drive to sleep it will put itself to sleep after 20 minutes of inactivity. Worse, once it is asleep the computer cannot wake it up!You can install a tool which is barely mentioned in the documentation called "Raid Manager" which allows you to disable the sleep timeout, but it will go back to 20 minutes every time the drives are powered off. You have to set it to zero every single time you turn it on.I don't understand companies that went through so much time and money to bring a product to market, then leave one HUGE FREAKING BUG in the software! The thing that is most easily fixed in their whole product cycle which creates such a huge end user experience failure.I'm reducing my 4 star rating to 1 star for a company that spent thousands of hours designing and bringing to market but won't spend an hour more fixing something that annoys every consumer,Bare-bones external drive array with minimal documentation. RAID 5 is becoming obsolete due to the size of drives on the market these days. The rebuild process when a drive fails is too prone to failure with such large disks. They really need RAID 6. RAID 10 is a viable solution, but obviously you only get 50% of your storage usable.Also, having so much data in one physical device is off-putting. Even if the disks were redundant the device itself is not, so really, if you want to have a 15 TB drive you probably should buy two of these and mirror them.My "low level" formatting throughput was 170MB/s.

Like most people, I was looking for a basic enclosure that had hardware RAID, at least USB 3 interface speed, easy to use, and didn't have a large number of bad reviews. This cabinet seems to fit the bill pretty well. It's relatively well made, no frills, easy to setup, and it comes with cables - firewire 800, eSata, USB, power, etc.I use this on Macs with OS 10.8X over Firewire 800, and Win-7 PC's with USB 2/3. No compatibility issues so far. Works with VMWare Fusion and ESXI too.Drives are easy to install in trays (well slots acutally), but I did have to reseat a couple of them to get the box to recognize them. Initialization is very quick, it does not seem to build parity data the way a lot of high end RAID cards do taking 1-2 days to complete on large arrays. It is relatively quiet and seems to run fairly cool.I bought this initially to stick in a bunch of 1TB drives I have laying around from server upgrades, and I have been using it to upgrade standalone VMWare ESXI boxen that are not Vmotion enabled. It has worked extremely well for that. My one complaint is the 5 minute power down feature. While I understand that most desktop or home users may find this a nice feature, it's an irritation for me. If I am using this drive to host VM's under VMWare Fusion, it has the nasty habit of powering down which sometimes causes the VM to have fits. I am trying to find a way to avoid this- it would be nice if there was a way to disable this feature.So far, very happy with this box, even if it was a little more than I wanted to pay. Seems to be good value for the money, no regrets on this one. DONT LOSE THE MANUAL, because you will need it to remember how to use the switches to initialize and delete arrays.

It started off great. The product itself seems sturdy. Setup was easy. Inserted 5 drives, configured raid, and everything worked great.About 5 days later, hard drive bay 3 started beeping. Unfortunate, and surprising given it was a new ironwolf drive. Disconnected, shutdown and went to swap out the drive.The raid enclosure never booted back up again.After that, i figured id check if the drive was actually bad. Put the "bad drive" in an external hub, and had no problems with it. Was able to format it, and write/read data.
