September 17, 20205 yr I have a new fresh install of unraid Version: 6.9.0-beta25 and I have selected my 10 drives to be part of the array. 8 of those drives are connected to an HBA, 2 of them are connected via USB 3.1 in an external 4 bay case. the 2 that are connected through USB keep dropping at around 1-2 percent: I know the drives are good, I cannot see them in system devices. This is the 4 bay device: https://www.amazon.com/Mediasonic-SATA-Hard-Drive-Enclosure/dp/B078YQHWYW/ref=sr_1_18?crid=17E73CTFH7K5G&dchild=1&keywords=4+bay+hdd+enclosure+usb-c+10gb&qid=1600316641&sprefix=usb+c+4+bay%2Caps%2C203&sr=8-18 The mobo is an Asus Zenith Extreme II Alpha if that matters. best i can tell, the usb enclosure is an HBA. Any Ideas? tower-diagnostics-20200916-2117.zip Edited September 17, 20205 yr by TheSkaz
September 17, 20205 yr We don't recommend using USB for array devices, as they are usually poor at error handling and have a tendency to drop.
September 17, 20205 yr This would be a better choice and use the eSATA port. https://www.amazon.com/Mediasonic-ProBox-HF2-SU3S2-SATA-Enclosure/dp/B003X26VV4/ref=psdc_160354011_t1_B078YQHWYW

I dont have an eSATA port. and dont have a pcie slot available. All 4 are taken. The only thing that I have open is USB 3, 3.1, and 3.2
September 17, 20205 yr The only difference between eSATA and SATA is the connector. You can get a cable that will go from one to the other. Note however that there would still be a bottleneck due to multiple drives on one port, and that would be very apparent with parity operations such as check, sync, rebuilding any disk.
September 17, 20205 yr Author I understand that, although I didnt know you could get a cable to go from one to the other. that is pretty cool. Full Disclosure: the whole system has 3 GPUs in 3 of the slots. in the 4th slot there is an 8 port HBA. so 8 of my drives are there. I am using 4 of the onboard sata ports. the other 4 are disabled due to an nvme drive in the back slot. I also have 4 other nvme drives. this is a new mobo and was trying to hook up all my drives. I have 2 more that I figured could go USB, but that doesnt work. If I could just get those last drives connected......

September 17, 20205 yr Author do you know how long I looked for one of those???? all I could find was expanders (and they still took up another pcie slot)
