Surveillance data is recorded on top of the old one, which means all writes are rewrites and that is the worst case scenario for a SMR drive.
A host-managed drive with carefully aligned zones may avoid this issue in this scenario, but I don't know how far a drive-managed SMR drive can mitigate it.
- scottlamb 7y agoThese drives don't even support TRIM. So I think as far as they're concerned, once the drive is filled, every write is a rewrite no matter the exact workload. I think the concept of drop-in, device-managed SMR, but let's try to hide that is nowhere near as good as what's possible with host management in terms of the write load it can sustain.
