ASUS BC-1205PT Blu-ray Combo

CD Write and ReWrite Tests - Nero Burning Rom 7.10.1.0 andDLA 5.20:

For this test I randomly generated 650MB and 700MB of files and directories to test the time it takes the drive to write and close a CD. All of the files are between 1MB and 25MB in size and no more than 10 directories deep.

The BC-1205PT uses Z-CLV, or Zone CLV, when writing at 24x. By looking at the screenshot above, you can see that it uses two "zones" to reach this. The drive starts writing at 16x and jumps to 24x at about the 19 minute mark.This gave ASUS's combo drive an average writing speed of about 22.07x.

To test the drive's writing times, I wrote our test data to some Taiyo Yuden manufactured Fujimedia rated at 48x. The results are below.

To test the drive's writing quality I used Lite-On IT's KProbe2. Written by Karr Wang, this utility can be used to test the number of C1 and C2 errors on a disc. For these tests I used a Lite-On LTR-52246S (firmware 6S0F) and read the discs at 32x.

Fuji 48x (Taiyo Yuden)

Memorex 52x (CMC)

Verbatim 52x

The BC-1205PT's writing quality was very good. By looking at the KProbe screenshots, you can see that the discs burned by the drive had a low number of C1 errors. More importantly, there were no C2 errors at all.

For the rewriting tests I created 400MB of files on the hard drive and wrote them in DAO mode using Nero. To test the packet writing speeds I copied and pasted the same files off the hard drive onto a CD-RW disc using DLA from Sonic. Verbatim's 24x Ultra Speed CD-RW media was used for these tests.

The BC-1205PT also uses Z-CLV when rewriting at 24x. As with CD-R media, it starts writing at 16x and jumps to 24x at about the 19 minute mark.

ASUS's new combo drive did fairly well in our rewriting tests. While not as fast as the GGW-H20L, it took 2:48 to write 400MB with Nero and 2:44 to do the same with DLA.

The BC-1205PT also erases at 24x. At this speed, it took the drive 15 seconds to do a quick erase and 3:53 to fully erase the disc.
