We’ve heard rumors for a while that Apple’s forthcoming Leopard operating system will use the next-generation file system called ZFS.
Now it seems to be official. As MacRumors.com notes, Sun Microsystems’ Jonathan Schwartz said on Wednesday that ZFS would be “the file system” for Leopard, succeeding HFS .
ZFS, which (sort of) stands for Zettabyte File System and was originally developed by Sun, is a huge step forward from traditional file systems. It protects all files with 64-bit checksums to detect and fix data corruption and, as a 128-bit file system, can handle many orders of magnitude more space than current versions of Microsoft Windows, OS X, or Linux. (There is a movement afoot to port ZFS to Linux but it’s complicated by restrictions in the GNU General Public License.)
