Lite-On SHM-165H6S Super AllWrite 16x DVD±RW/RAM

CD Write and ReWrite Tests - Nero Burning Rom 6.6.0.16 andDLA 4.95:

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. All of the times below include not only the actual writing time, but the lead in and out times too. This gives a more realistic idea of how long it takes to write a CD.

 

The SHM-165H6S has a maximum CD writing speed of 40x. To reach this speed, it uses CAV, or Constant Angular Velocity. With Fuji's 48x media, the drive started writing at about 21.06x and reached a maximum speed of 48.79x at the end of the session. This gave Lite-On's new DVD±RW an average writing speed of about 36.96x.

To test the SHM-165H6S's writing times, I wrote our test data to some Taiyo Yuden manufactured Fujimedia rated at 48x. The results are below.

Lite-On's new drive did very well in our CD writing tests. Thanks to its 48x CD writing speed, the SHM-165H6S was able to write an entire 650MB CD in 2:32, beating the drives from NEC and LG by about 25 seconds.

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 SHM-165H6S'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 and 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.

While the SHM-165H6S uses CAV when writing to CD-R discs, it uses Z-CLV, or Zone CLV, when rewriting at 24x. The drive starts rewriting at about 16x and then jumps to its maximum speed at the 13 minute mark..

While the drives from NEC and LG can rewrite at 32x, the SHM-165H6S has a maximum rewriting speed of only 24x. As you can see, this put Lite-On's new DVD writer at a disadvantage in our tests.

The SHM-165H6S also erases at 24x. While this didn't have much of an effect on the drive's quick erase times, it took nearly four minutes to do a full erase.
