I'd like to poll people about RAID configs for SSD drive arrays.
It's actually a more complex problem then what you would think at first glance.
Striping is probably pointless.  Raid 6 is not advised, because every SSD is touched by every write, so the DWPD counter goes up simultaneously, 
causing all SSDs to expire simultaneously.
I'm now looking at more exotic solutions like RAID-15 (two raid5's mirrored)
