I currently am using 4 Western Digital Ultrastar DC HC570 22TB drives in BTRFS RAID5 (yes, I know the risks). It's been running perfectly for about a year and a half at this point, with no errors or any other signs of imminent drive failure. That being said, I want to order 2 more drives to use as warm spares.

I can get 2 more HC570 drives or I can get 2 Western Digital IU HA570 WD240EDGZ 24TB drives for $10 more each. I'd like to know about any positive or negative experiences people here might have had with the HA570 drives so I can decide whether or not to get those or just get 2 more HC570.
