TheSkaz Posted September 17, 2020 Share Posted September 17, 2020 (edited) 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, 2020 by TheSkaz Quote Link to comment
JorgeB Posted September 17, 2020 Share Posted September 17, 2020 We don't recommend using USB for array devices, as they are usually poor at error handling and have a tendency to drop. Quote Link to comment
Frank1940 Posted September 17, 2020 Share Posted September 17, 2020 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 Quote Link to comment

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 Quote Link to comment
trurl Posted September 17, 2020 Share Posted September 17, 2020 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.

TheSkaz Posted September 17, 2020 Author Share Posted September 17, 2020 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...... Quote Link to comment

Replace with 16 port. https://www.broadcom.com/products/storage/host-bus-adapters/sas-9305-16i Or, depending on the 8 port you have, get a SAS expander. Quote Link to comment
TheSkaz Posted September 17, 2020 Author Share Posted September 17, 2020 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) Quote Link to comment
