Write speeds on SMR drives start to stagnate after mere gigabytes written, not after terabytes. As soon as the CMR cache is full, you’re fucked, and it stagnates to utterly unusable speeds as it’s desperately trying to balance writing out blocks to the persistent area of the disk and accepting new incoming writes. I have 25 year old consumer level IDE drives that perform better than an SMR drive in this thrashing state.
Also, I often use hard drives as a temporary holding area for stuff that I’m transferring around for one reason or another and that absolutely sucks if an operation that normally takes an hour or two is suddenly becoming a multi-day endeavour tying up my computing resources. I was burned once when Seagate submarined SMR drives into the Barracuda line, and I got a drive that was absolutely unfit for purpose. Never again.
