Hi Joe,



We have seen this issue earlier. In OFA driver, more time is taken for format because the maximum number of LBAs to unmap is less compared to value set by MS driver.
We have to increase the maximum number of LBAs to unmap in SntiTranslateBlockLimitsPage() in pBLPage->MaximumUnmapLBACount.



Thanks,
Suman

Title : [nvmewin] device formatted time


Hi, Everyone,
I have a formatted time issue with OFA driver on windows 10. I use a 256GB Nvme drive to test. Device’s formatted time costs about 40~50 seconds with OFA driver, but it only costs 1 ~ 2 seconds with Microsoft inbox nvme driver.
Is there any chance to improve it?
Thanks,
       Joe#3138
