BD Write and ReWrite Tests - Nero CD Speed v4.7.7.16:
To test the BD writing performance of Lite-On's new drive I used BD-R and BD-RE media from Memorex, Sony, TDK and Verbatim. To get the writing times, CD Speed's "Create Data Disc" feature was used. I also ran the discs through CD Speed's transfer rate test to make sure that the DH-4B1S could read them back. .

The DH-4B1S writes to BD-R media at 4x. Looking at the screenshot above, you can see that the drive starts writing at 3.3x and then jumps to 4x at the 1GB mark.

| BD-R | 24:05 | 21:25 | 27:29 | 45:22 |
| BD-RE | 46:25 | 39:24 | 45:14 | 45:03 |
| BD-R DL | failed | 44:57 | 90:22 | 90:34 |
The DH-4B1S performed fairly well when writing to BD-R media.While not as fast as the GGW-H20L, it took a little more than 24 minutes to burn an entire 25GB disc. Unfortunately, Lite-On's new drive failed when writing to Sony's BD-R DL media. After 90 or so minutes, the DH-4B1S locked up, causing CD Speed and eventually Windows to hang.

| Verbatim 25GB 2x BD-RE | VERBATIM0 | 2x | 46:25 | Transfer Rate |
Aside from the problems with Sony's BD-R DL media, burning Blu-ray Discs went off without a hitch. The DH-4B1S wrote to all of our test media at its rated speeds and, looking at the transfer rates, you can see that it had no problems reading the discs back.
Performance Revisited:
While Lite-On's Blu-ray Disc writer has a few rough spots, it performed as expected throughout most of our tests. The DH-4B1S worked well with all of the BD-R and BD-RE media I tried, but had some issues with BD-R DL discs. Reading and writing to CD's and DVD's wasn't a problem for the drive either. The DH-4B1S had no problem reaching its rated read speeds and held its own fairly well in our writing tests. With all things considered, the Lite-On DH-4B1S gets a 7 out of 10 for the performance section of this review.
