Mac OS X Developers have received from Apple a 'ZFS on Mac OS X Preview 1.1' package, which offers preliminary support for the ZFS file system, originally developed by Sun Microsystems for their Solaris OS. Currently, the Mac OS is based on the HFS+ file system, but leaked screenshots of earlier versions of Leopard showed options for formatting hard drives for ZFS. Reportedly, this preview allows full read and write capabilities with the latest developer build of Mac OS X 10.5 Leopard, Apple's upcoming version of its OS X operating system.

The Sun X4500 thumper which has dual(?) opterons and 6 SATA cards with 48 discs with 500GB, achieve 640MB/sec read. So, yes, the guy achieved over 100MB/sec. But he had 64bit CPU. There can be dramatic performance increase if you double the number of bits, right? I achieve now, 32bit P4 1GB RAM, 30MB/sec. I cant wait till I get a Penryn which could play in the same ballpark as dual opterons, in terms of performance. I will easily achieve over 100MB/sec then.
