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.
