These are "enterprise" SSDs. I'm guessing the 150GB model will be in the $20K to $30K range. They're gunning for STEC's current domination with the big-iron vendors, not trying to compete with Intel and OCZ and Samsung in the "enthusiast" market. They've got the performance numbers to beat STEC, so they just need to set their price just low enough to convince all of the big-iron vendors to switch from STEC to Pliant SSDs.
There's no question that these drives perform well under most server workloads, that's what they've been designed to do, but I would love to see someone actually benchmark one of these drives on a gaming and/or office system just for fun. They're almost certainly not worth the money in anything but a heavily loaded server, but it would be good to know where they would stand.
