Apple Says 'No ZFS' in Leopard
19 Comments
Apple executives at WWDC said that Mac OS X Leopard will not use Sun's ZFS 128-bit file system, contrary to reports that surfaced last week. Apparently, somebody forgot to tell Sun CEO Jonathan Schwartz, who told a conference that Apple would announce the switch Monday.
Instead, Leopard will continue to use HFS+, the file system currently found in Mac OS X Tiger. The news is disappointing to many Apple enthusiasts who were looking forward to the improvements ZFS would have brought, including checksums to protect data integrity, disk snapshots for backups, and virtually unlimited storage space.
