Storage enthusiasts (yeah, there is such a thing - what of it?) would probably tell you that PCIe-based SSDs are a dime a dozen these days. But in all seriousness, the prices we're seeing are proof that a few more competitors wouldn't hurt. A few weeks back, Austria's own Angelbird started to ship a solution that we first heard about during 2010, and we were fortunate enough to pop a Wings PCIe SSD RAID card into our Mac Pro for testing. For years, we've been booting this up and running every single application off of its stock HDD - a 640GB Hitachi HDE721064SLA360 (7200RPM) - as we surmise many of you desktop owners might be.
