SSD for FreeBSD NAS device

Hello, 

I have just acquired an Intel R2312GZ4GC4 which I have equipped with a Adaptec RAID 51245 and 6 WD red disks of 3To - It'll come with 32Gb of Kingston ECC RAM. 

I am planing to use It as a backup device on a second hosting facility to backup couple of critical servers of mine.

I will use ZFS as file system for both the root drive (SSD ?) - and the Adaptec RAID / JBOD controller (RAIDZ2 probably).

I wanted to know what were your experiences on choosing an SSD HD as master boot device / root FS ? 

Do you think I should go for a redundant SSD drives (RAID 1) or does this offers limited interest in such config ? 


I have been reading comments about "failure" / problems here and there, but comments are not so fresh (one year is very old in SSD). 

So I wanted to have fresh infos and updates on your experiences with SSD on such mid size system. 


Thx.
