Nice mechanical build quality, but I bought this to host hot-swappable drives for a software RAID. Unfortunately, when you eject *one* drive, it tells the host computer that *all* of the drives have been removed. As a result, you have to take all the drives offline before replacing *any* one of them. That completely defeats the point of a hot-swappable drive enclosure. Read more

If you're on Linux and struggling with autosleep features, you can run a cronjob every 5 minutes to "touch" the disk to keep it alive. sudo crontab -e for each drive you want to keep awake enter a line with your correct filepath instead of "/your/hdd/mnt/here": */5 * * * * /bin/touch /your/hdd/mnt/here &>/dev/null Windows has something similar with a keepalive program if you search around for it. I was unable to change any of the hw parameters to disable the settings. so this was my only workaround. Read more

I am disappointed as the item showed up damaged ( as other have had happen ) it was not hard to fix for someone like me that enjoys fixing things, but I feel this happened when it was boxed as the package was not damaged. I think the manufacture should have some better quality control. the only other issue I have with the issue is the doors on some of the drive bays don't open far enough to put the drive in easily. for the damage see attached photos. other then those issues I have not had any other issues with the drives working within windows.

Orico 5 bay model 9558RU3, a replacement for Orico DS500C3 work well. Model DS500C3 will go to sleep, not easy to wake up on the server and network I had to remove 3 of them, purchase 6 of the new one. SOLID PERFORMANCE!! will recommend highly. thanks George Omoregie Read more

Maybe the product is ok and I just had bad luck and got a defective unit. Problem was a little unusual. Unit powered up, and disks inserted were seen by the disk management system and could be formatted ok, but it was slow. Once formatted the performance of any HD in the enclosure was terrible. Transfer rate was 20 % normal or less, and would only work for one disk at a time. The problem was for the whole enclosure and not any particular slot -I tried them all. Tested with Seagate, Toshiba and Arsenal drives in the Orico and verified the disks to be good in a Sabrent enclosure. Tried every USB port and swapped cables a few times. Same results, perfectly good drives had snail paced read/write speeds. OK no problem, I'll return it. Then the real fun begins. I apply for a RMA. Very quickly Orico sends back an email saying they don't understand the problem. I send them back a page long description of the problem, including exquisitely detailed troubleshooting steps and test results from SEATOOLS, Crystal, etc. and send it off. Again a pretty fast response comes back (like 24 hours): They still don't understand the problem, can I send them a video? Huh? A video of a disk not transferring data? Am I supposed to installed stream capture equipment on my server to uplaod like a YouTuber? Or set up a video camera to watch my monitor screen for the hour or two it takes to write a .txt and then upload the multi GB file to them somehow? Or did they want some kind of home movie showing me setting up the enclosure and inserting a disk drive? That all seemed ridiculous and frankly I to this day think the ask for a video was just a dodge of some kind. I did send them screen captures of the test results comparing a couple of Disks in the Orico and the same two disks in a Sabrent, along with the results printouts, but apparently JPEGS won't do in place of a "video". I got a third response back saying they couldn't proceed with the return without a video. At this point I got Prime involved and just got a refund. Maybe Orico should stick to weird little board part adapters and stuff. I would at least commend them for their quick responses, but I suspect the responses were just bot nonsense meant to discourage complaints. Read more

This specific model dont have a RAID controller inbuilt, the product descriptions were not accurate or detailed enough to understand the differences. It works fine as hardware enclosure, you can use multiple bays with different HDD capacities and windows will recognize them as a mass storage units. The transfer speeds are just okay dont expect the lightning fasts. For me im just taking the data backups and is okay. The max drive i used is 4 TB in a single closure and 2 TBs in the rest.
