Thanks for your input, Neil.
My ATTO / E8 combo isn’t a JBOD. It’s a RAID, and I’m running it as a RAID6 currently.
You are correct that ATTO has discontinued calling their RAID adapters by that name, and are calling them HBAs. They’ve also discontinued the 6 Gbs line for 12 Gbs products.
If I end up needing a new PCIe HBA, I’m going to need to reformat the drives in my RAID and get a new enclosure and cables. ATTO has also discontinued SAS connectivity for Mini-SAS.
Therefore, having a completely separate backup RAID in my QNAP seems like a keeper of a plan. I’ve only run a few tests editing off the QNAP, and I’m confident the i/o speed will be adequate for 4K editing should I need to use that device for editing should I need to put it in service for that.
Sorry for my tardy reply. I had notifications disabled.
