> Benchmarking results show that SSDFS is capable:
Is there performance data showing IOPS?
These comparisions include file systems that don't support zoned devices
natively, maybe that's why IOPS comparisons cannot be made?
> (3) decrease the write amplification factor compared with:

> 14x - 42x (xfs),
> 6x - 9x (btrfs),
> 1.5x - 50x (f2fs),
> 1.2x - 20x (nilfs2);
> (4) prolong SSD lifetime compared with:
Is this measuring how many times blocks are erased? I guess this
measurement includes the background I/O from ssdfs migration and moving?
> 1.4x - 7.8x (ext4),
> 15x - 60x (xfs),
> 6x - 12x (btrfs),
> 1.5x - 7x (f2fs),
> 1x - 4.6x (nilfs2).
Thanks,
