I just found out that Ten's Compliment postponed their Zevo Gold and Platinum editions from "Spring" to "Summer" . Zevo is a replacement for HFS+, OS X's current filesystem, considered to be quite outdated. About Zevo and Ten's Complement (from Wikipedia): In January 2012, the company Ten's Complement LLC released a ZFS implementation for Mac OS X called "Zevo" which includes both GUI and command-line features. As of January 2012, Zevo implements zpool version 28, the same as FreeBSD 9.0. The first "Silver" release of Zevo does not include compression, snapshots, or RAIDZ, although it does enable checksumming. Future releases of Zevo, slated for release later in 2012, will offer additional features. The company was founded by Don Brady, a former Apple engineer who was technical lead on the original HFS+ team and worked on Apple's abandoned internal project to port ZFS.
