Excerpt:
"However, SMR drives are not intended for random write IO use cases because the write performance is much slower than with a non-SMR drive."
Might this be a way to detect SMR usage by allegedly non-SMR drives?
Do a whole lot of random write IO -- and time and statistically sort the results?
- wtallis 7y agoIt should be pretty easy to detect SMR. It's probably sufficient to just compare random read and random write performance and look for a big disparity. Probing for cache size and zone size would be a bit trickier.
