Thanks all! I will check out FreeNAS and see what it can do... I will also check my RAID Card and see if it can work with JBOD... fingers crossed... The machine has a couple internal SATA ports (think there are 2, could be 4) so i was thinking of using those for boot disks and SSDs later...
As a follow up question: Data Deduplication: The machine, to start, will have about 5Gb RAM. I read somewhere that 20TB storage would require about 8GB RAM, depending on block size... Since i dont know block sizes, yet (i store a mix of VMs, TV Shows, Movies and backups on the NAS)
Consider using different policies for different data. For traditional file systems, you
had relatively few policy options: readonly, nosuid, quota, etc. With ZFS, dedup and
compression are also policy options. In your case, dedup for your media is not likely
to be a good policy, but dedup for your backups could be a win (unless you're using
something that already doesn't backup duplicate data -- eg most backup utilities).
A way to approach this is to think of your directory structure and create file systems
to match the policies. For example:
/home/richard = compressed (default top-level, since properties are inherited)
/home/richard/media = compressed
/home/richard/backup = compressed + dedup
I am not sure how much memory i will need (my estimate is 10TB RAW (8TB usable?) in a ZRAID1 pool, and then 3TB RAW in a striped pool). If i dont have enough memory now, can i enable DeDupe at a later stage when i add memory? Also, if i pick FreeBSD now, and want to move to, say, Nexenta, is that possible? Assuming the drives are just JBOD drives (to be confirmed) could they just get imported?

I need something that will allow me to share files over SMB (3 if
possible), NFS, AFP (for Time Machine) and iSCSI. Ideally, i would
like something i can manage "easily" and something that works with
All of them should provide the basic functionality you're looking for.
None of them will provide SMB3 (at all) or AFP (without a third
FreeNAS has AFP built-in, including a Time Machine discovery method.
The latest FreeNAS is still based on Samba 3.x, but they are aware
of 4.x and will probably integrate it at some point in the future.
Then you should have SMB3. I don't know how far along they are...

FreeNAS comes with a package pre-installed to add AFP support. There is no native AFP support in FreeBSD and by association FreeNAS.
