My main point was not really this particular device, but parallel SSD's in general. It's changing the way we think about persistent storage for write-often data.
From a quick google, it looks like the 80GB model starts at $2400. Hard to call that competitive with SSDs, except soley on performance.<p>Should be very interesting for "dream machine" desktops once you can boot from one.
So, thinking about the "standard" MySQL scale-out approach of master/slave coupled with memcached, what's the new best practice if you have a stack of iodrives sitting around?
