Would it make sense for me to convert my 60Gb storage to it? Thanks! -mi The primary difference at this point is that UFS2 can support filesystems bigger than 1 Terabyte. It will eventually support extended attributes (up to 32Kb of extra stuff associated with each file such as access-control lists and/or alternative representations of the file such as an icon). UFS1 already gets about 90% of the disk bandwidth, so there is little room left for speed improvements for big files. UFS1 also has soft updates which gives most of the available performance for small files.
