Would ZFS be a good idea for a Media Server

I have a PC with 8GB of RAM running on an Intel Processor Duo Core (64bit).

My configuration is as follows:
  • 128 GB SSD for OS and website jail
    2, 256GB drives as a RAID backup.
    3 TB Seagate for storing video and audio recordings
    1 GB WD Green drive, file storage.

I'm running MythTV with two tuners. I may increase that to four. I will be running several low volume web sites with email, in a jail. The webs sites are just simple blog sites.

Would I benefit from using ZFS across all the drives? It seems I would need to have about 5GB of RAM for the ZFS system.

Do I need ZFS for jails?

The feature I like about ZFS is the snapshot feature.

Reliability and up time are important.

That's a "rule of thumb", not a hard limit. My home server runs just fine with 4 GB of RAM and serving about 11 TB of ZFS storage ( 4 x 3 TB RAID-Z and 3 x 500 GB RAID-Z). Mostly movies, TV shows and the odd documents I have shared with Samba. Don't enable dedup though, that's going to kill the machine. Compression on the other hand should be fine at the expense of a little more CPU load.

It's not a necessity but it makes working with jails a whole lot more fun. It's quite easy to set up a "base" jail and use zfs clone to make multiple copies in the blink of an eye.
 
Thank you. ZFS it is. It took a little while to get everything moved around. I did some "drive" cleaning as well.

Definitely no on dedup. I don't have the RAM and I don't see where I would benefit from enabling it.
