Compelling reasons to switch ?

Nearly 20 years ago, after the first few releases of ntfs-3g fixed the initial performance issues with large files, ntfs-3g was much faster than HDDs anyway. When dealing with a PCIe Gen5 NVME SSD sporting millions of IOPS and a transfer rate in the GB/s range, there could be a speed and/or CPU consumption difference between a kernel space filesystem and a user space filesystem, right. However, it remains to be seen whether the latter isn't good enough for _most users_ on those metrics.

I guess I'll wait for benchmarks to be posted on e.g. Phoronix.
