I have several DM-SMR drives and their write cache (when not completely full) is like 50-100 GB large. As long as you don't write more than that in one go it performs exactly like a normal hard drive of their stature. When they're idle they'll merge the write cache into the main SMR region. Sequential writes mostly end up going straight to the SMR region (there is no idle-reorganization after them). SMR is also only used in fairly high capacity drives. A 1/2/4 TB drive wouldn't be SMR.

>SMR is also only used in fairly high capacity drives. A 1/2/4 TB drive wouldn't be SMR. I thought so too, until I bought a 2TB and discovered it's SMR. It turns out there are quite a few 4TB SMRs, and also 2TB and even 1TB SMRs. e.g. https://www.truenas.com/community/resources/list-of-known-smr-drives.141/ https://www.truenas.com/community/resources/list-of-known-sm...
