Is this a UFS extended standard or vendor specific feature?
Hi Bean,
This feature has been standardized by JEDEC. My feedback to the sponsors
of this feature a few months ago was that FBO will become obsolete once
all UFS devices support Zoned storage for UFS. The FBO standard defines
an interface for telling UFS devices about the relationship between LBAs
and files. This allows UFS devices to defragment files. UFS devices
won't need that information for zoned LUNs since for zoned LUNs the host
software will be responsible for ensuring that files occupy a contiguous
range of LBAs.
Thanks,
Bart.
