Mac OS X Perhaps overcome with excitement (and forgetting that Apple doesn't like such pre-emptive disclosures), Sun's Jonathan Schwartz announced today at Sun event in D.C. that Apple would be making ZFS 'the file system' in OSX 10.5 Leopard. "In fact, this week you'll see that Apple is announcing at their Worldwide Developer Conference that ZFS has become the file system in Mac OS X."

Could it be true that all features of the ZFS filesystem also have the compromise of needing (much) more RAM and CPU, thus shortening battery life, for more speed and better cache.
It might not be the best for a laptop.

@ Chicobaud

If you read in the end of my comment, I say that ZFS providing a much more optimized I/O and disk operation the battery life time should actually improve quite significantly.

Now that Apple is also fitting LED displays and Intel delivering even more efficient less power-hungry CPUs, I believe generally the battery life can improve a lot.

Remember this is a file system, not a piece of hardware or an application.

ZFS is *very* RAM hungry. Using it on 32-bit systems with 512 MB or less can lead to kernel panics. The sweat spot seems to be around/above 1 GB of RAM.

On 64-bit systems, it's a lot smoother and runs better, even with just 512 MB RAM.

It can also lead to a lot of disk I/O.

See the archives of the FreeBSD stable and current mailing lists for more info (mostly FreeBSD specific, but with links to Solaris info).
