Silence, speed, transfer rate are the major assets of this disc. No "click" to start or read-write (which is not the case of Blue series). Heater bit: 27-33 ° for 4 hours intensive use (video games). Regularity of speed measured: + or - 1 / 1100th of a turn with independent PC hard disk monitoring tool. With 6 discs of this type in use on my PC, the oldest is 7 years old, I can only underline the reliability of this series.
