1. Adopting 32 bit to record number of allocation
blocks: In HFS+
partition, there could be 232 allocation blocks at most in one partition.
And adopting 16 bit to record number of allocation blocks, HFS only allows 216
allocation blocks at most in one partition. In HFS+ partition and HFS partition
which have the same sizes, number of allocation blocks in HFS+ partition is
larger than that in HFS partition. Thus, HFS+ partition has smaller allocation
blocks and improves space use ratio and increases storable file number.
Supporting long file name: HFS+ supports file names with a
length of 255 characters and HFS only supports 31 characters. So HFS+ can
describe files more accurately.
3. The size of directory tree node
increases to 4KB: HFS+ not only has larger directory tree node, but
also is able to change storage node size according to size of index node, which
reduce wasted space and create a directory structure storing more information
for quick index on ever accessed files.
4. Single file size is 263
bit at most: HFS+ supports single file of 263 bit at most and HFS only
231. So HFS+ can satisfy users' demands for large file storage.
Faster boot speed: HFS+ identifies a boot fie with location and
file size information in partition head. This boot file can be found easily when
system boots, thus quickening system boot speed.
Since HFS+ has so many
advantages, many users have converted HFS to HFS+ in Mac. Then we'll introduce
