The second step of the test was very short. It didn’t take the drive long to read a Sony BD-RE 2x. Here’s a photo of the disc and its characteristics:
I had burned the disc on our drive itself and the burning had taken much longer. Our version of Nero Burning ROM cannot burn Blu-Ray media and I first tried the free utility AVS Disc Creator. Sometimes it’s good to extend the list of software you use.
AVS Disc Creator recorded the BD-RE all right, but I was somewhat alarmed at the time spent. It took 2 hours 33 minutes at a speed of 2x. This looked rather too long to me, so I tried to burn the disc once again in Ashampoo Burning Studio. This program has a smaller distribution size in comparison with Nero Burning ROM.
This time it was all within a reasonable time. It took the drive about 46 minutes to burn the disc as is shown in the screenshot. By the way, the actual maximum amount of data you can write to a 25GB disc is 23.31GB. The manufacturers measure the disc capacity using a decimal rather than binary system just like HDD makers do.
The read speed diagram shows that the disc is being read at a constant linear velocity.
There’s nothing much to comment upon. The read speed of the BD-RE disc is 2x, just as expected. The measured access time is very small in comparison with the value the manufacturer specifies for BD-ROM.
