Re: New file system
Not really. Each have competing needs.
ext, for example, scatters writes around the disc in a pattern because it assumes multiple people will be accessing the system at the same time which makes for a very random assortment of disk accesses.
ZFS was designed for use on large systems. Its logical limits surpass physical limitations, removing the need to worry about them. Meanwhile, its designers understood the problem of silent corruption (where the odds of it happening increase with size), so it sacrifices a little capacity and performance so as to be able to better catch these spontaneous corruptions.
FAT and NTFS, OTOH, assume a low user count and are designed to better allow the compacting of the file system so one can better perform sequential reads. NTFS takes the extra step of preferring its master file table towards the center of the disk to reduce the average seek time.
I'm just listing a couple of their more distinguishing traits. Basically, with different goals you get different filesystem structures, each with their pros and cons.
