On one system, yes. Others, I just have an 18 or 20 TB drive that can handle my whole backup.
That is just one part. Putting a raid card in a desktop motherboard with four different brands of 10TB drives is not server grade in my opinion. The motherboard, power supplies, disks, and even case (Lots of air flow) should be higher quality and meant for servers/NAS.
My current primary server is an Asrock Rack single socket xeon (e5-2697v3) motherboard with ipmi and ECC ram. My spinning disks are either NAS-grade WD drives or enterprise Seagate drives. Power supply is platinum efficiency EVGA PSU with 10 year warranty. It is in a fairly cheap case but all cpu (2) and case fans (3) are Noctua 120mm. My system doesn't have much for automatic redundancy but I'm not too worried if it goes down and I have to swap a PSU. I have multiple full backups of my data on the primary server and other servers. I have a couple of 8TB offline drives for cold storage. I also have an LTO-6 tape drive that I create archives occasionally to store offsite.
Do you really have that much data? I also use enterprise drives Toshiba. Thanks for that Rye learning everyday.
