Another manufacturer has tossed their hat into the solid-state disk ring. Attorn BV has recently announced their upcoming SSD drive dubbed the HyperDrive4.
The performance of this new drive is just incredible. It touts a hefty 126MBs/s with a single drive. Bump it up to 4 in a RAID 0, and you'll be able to see speeds up to 400MBs/s.
