ZFS has the following advantages:
- Large file size: 16 Exabytes

- Large volume size: 16 Exabytes

- open-source

- 128-bit filesystem (hence, the 16 EB max)

- Copy-on-write feature where blocks of data are written to, and new data is allocated. Also:
"An advantage of copy-on-write is that when ZFS writes new data, the blocks containing the old data can be retained, allowing a snapshot version of the file system to be maintained. ZFS snapshots are created very quickly, since all the data composing the snapshot is already stored; they are also space efficient, since any unchanged data is shared among the file system and its snapshots."

Does that remind anyone of OS X's "Time Machine" feature? It sure does to me. And, thus I think ZFS is or can be used for that reason because of its efficiency.

- improved I/O throughput and write load

There are more features that are listed, but it sounds better than the other currently used filesystems:

FAT32
- Maximum file size is 4 GB
- Max. volume size is 8 TB
- 32-bit
- proprietary, closed-source; requires license from Microsoft

NTFS
- Max file size is 16 TB currently; architecturally 16 EB (not yet implemented)
- Max volume size is 16 TB currently; architecturally 16 EB (not yet implemented)
- proprietary; closed-source; requires license from Microsoft

HFS+
- Max file size is 16 EB
- Max volume size is 16 EB
- Mac OS X only

Of course, you can just read Wikipedia and it'll tell you more in detail. I don't want to make this post longer than it already is.]]>Jun 26th 2007 3:18PMhttp://www.engadget.com/2007/06/26/read-write-zfs-beta-for-leopard-reportedly-sent-to-developers/http://www.engadget.com/2007/06/26/read-write-zfs-beta-for-leopard-reportedly-sent-to-developers/http://arstechnica.com/staff/fatbits.ars/2006/08/15/4995

This fatbits on ars gives the best arguments I've seen for ZFS on OS X]]>Jun 26th 2007 3:57PMhttp://www.engadget.com/2007/06/26/read-write-zfs-beta-for-leopard-reportedly-sent-to-developers/http://www.engadget.com/2007/06/26/read-write-zfs-beta-for-leopard-reportedly-sent-to-developers/
These linux, BSD and unix file systems are perfectly fine for their uses. While ZFS sounds interesting, for the average user and probably beyond, it will most likely be overkill.]]>Jun 26th 2007 4:06PMhttp://www.engadget.com/2007/06/26/read-write-zfs-beta-for-leopard-reportedly-sent-to-developers/http://www.engadget.com/2007/06/26/read-write-zfs-beta-for-leopard-reportedly-sent-to-developers/
1. Log in to your or create a free account on developer.apple.com
2. Click on "Downloads"
3. Download (as of today) the free beta ZFS version for Leopard and (gasp) Tiger (which, yes, can write ZFS as well)]]>Jun 26th 2007 2:55PMhttp://www.engadget.com/2007/06/26/read-write-zfs-beta-for-leopard-reportedly-sent-to-developers/http://www.engadget.com/2007/06/26/read-write-zfs-beta-for-leopard-reportedly-sent-to-developers/http://connect.apple.com and browsed to "Downloads" but don't see a free beta of ZFS for Leopard/Tiger.]]>Jun 26th 2007 3:32PMhttp://www.engadget.com/2007/06/26/read-write-zfs-beta-for-leopard-reportedly-sent-to-developers/http://www.engadget.com/2007/06/26/read-write-zfs-beta-for-leopard-reportedly-sent-to-developers/Jun 26th 2007 3:41PMhttp://www.engadget.com/2007/06/26/read-write-zfs-beta-for-leopard-reportedly-sent-to-developers/http://www.engadget.com/2007/06/26/read-write-zfs-beta-for-leopard-reportedly-sent-to-developers/
Theres no chance of file corruption...]]>Jun 26th 2007 4:59PMhttp://www.engadget.com/2007/06/26/read-write-zfs-beta-for-leopard-reportedly-sent-to-developers/http://www.engadget.com/2007/06/26/read-write-zfs-beta-for-leopard-reportedly-sent-to-developers/Jun 26th 2007 3:43PMhttp://www.engadget.com/2007/06/26/read-write-zfs-beta-for-leopard-reportedly-sent-to-developers/http://www.engadget.com/2007/06/26/read-write-zfs-beta-for-leopard-reportedly-sent-to-developers/
This probably isn't an appropriate request, but can anyone point me in the direction of a place to download the ZFS r/w beta that was pulled from Apple's site?
