FastlaneHW posted a review on the Matrix Orbital MX630 Display

In this review we are going to look at the Matrix Orbital MX630, a 2-line display unit for your 5.25 inch drive bay that uses a new display technology - the PLED (Polymeric Light Emitting Diode). The PLED offers lower power consumption, a wider viewing angle (about 160 degrees), and a faster response time than LCD displays.
