I'm using it on solaris10, but I hear it's partially supported on Freebsd (it might be fully supported now I haven't looked in about 5 months). I think the GPL makes it not possibly on linux without a special kind of port. I don't notice any difference on read/write performance from prior to using ZFS. The dynamic striping writes at all devices in the pool at the same time. I'm using it primarily for Mysql databases but it can be used for any database. If you are on the Mysql side of things a very handy video I came across was this:
http://recordings.dimdim.com/view/dimdim/b4544fb0-605b-102c-9991-003048944478 It's 50 min long but well worth the watch if you are planning on getting your feet wet. Why use ZFS ? Here's an article that kind of sums it up http://www.tech-recipes.com/rx/1446/zfs_ten_reasons_to_reformat_your_hard_drives/ The main reasons I use it is the ease of its software raid, the compression it offeres to save as much space as possible, and the most important to me being able to scale up hard drive space in a production environment on the fly. Running low on hard drive space? just pop in the drive in live and add it to the zpool. You've just increased your storage array without any reboot or downtime. disk goes bad? pull it out put a new one back in and ZFS resilvers the disk to it's identical state with no downtime. Also the idea of partitions is gone, it's all pools now.
