I agree, PFS3 is great and it is 100% compatible.
Plus it has direct scsi support.
But if it comes down to facts well:
1. 500% faster read/writes and scanning directories. The performance gain varies with depending on devices, buffers and processor but gains of upto 500% are no exception.
2.Disks are always valid, no matter what happens, its called Atomic Commit. More info in PFS3 Docs.
3. Reliability - very reliable and stable filesystem. Has built in problem detection mechanism. When PFS3 detects a problem it will do everything it can to save your data (see problem detection)
4. Parralel access without performance loss.
FFS breaks down when you try to do several things simultaneously on one volume. PFS3 does not!.
5. Full Compatibility.
PFS3 is fully compatible with FFS at filesystem level, but for a few rarely used filesystem packets. What this means is that practically all tools and applications that use the filesystem to access the disk work. All normal applications do this, including most backup tools.
Some applications, however, access the disk directly, bypassing the filesystem. Such applications won't work if they expect a FFS disk. Examples are disk optimisers and repair tools (like Quarterback Tools and DiskSalv).
Such tools have to be specially made or adapted in order to function with PFS3. The reason those tools don't work is that PFS3 stores
information differently on the disk than FFS does. In fact, PFS3 does this in a more efficient and reliable way.
The only feature of FFS that is not supported by PFS3 are record locks. Not a single application that uses this FFS feature is known to us.
6. Easy Filerecovery - lost files can be restored from the delete directory. This includes overwritten files.
7. Long filename support - supports 107 characters
8. Automatically truncated logfiles - stopping them from growing indefinitely.
9. Large disk support - pfs3 supports disk and partitions of upto 104GB using the direct scsi and TD64 interfaces.
10. Multiuser support - a multi user system turns PFS3 into a MuFS replacement. It adds user based access rights to the files on the disk. Each file and directory can be assigned to specific users and user groups. The owner of a file can determine who may have access the file.
The ONLY issue i have had with PFS3 is if you dont follow the advice in the documentation and set the incorrect mask values and pfs3 driver, then your get problems on the disk.
But even this is recoverable to another partition as long as you act quickly rather than leaving it for weeks.
