Work with CD-RW Discs
We’re finished with write-once media. Let’s do some rewriting.
It takes about the same time to burn a CD-RW disc at 32x and 24x speeds. The AOpen COM5232/AAH was nominally the fastest at 32x (by the way, the firmware update didn’t affect the burn speed in the slightest), while the Samsung TS-H492A won at 24x speed. The Samsung SM-352N was the only drive to go off the rails, with 32x discs. As you remember, the main difference of this model from the SM-352B is a faster declared rewrite speed (32x instead of 24x). However, the SM-352N refused to burn our test medium (Verbatim 32x disc) at a speed higher than x16 – maybe due to certain defects in the firmware. Will they correct them, considering the release of the TS-H492A? I guess not. Samsung was very quick in releasing the new model – my tests explain why.
Now, let’s discuss the quality of writing CD-RW discs. We start out from 24x speed.

The firmware update didn’t affect the result of the AOpen COM5232/AHH. All the drives handled the test disc successfully, in about the same time. The Samsung TS-H492A reached its maximum speed earlier than the other devices as it started burning at 20x rather than 18x as the other two. Anyway, this didn’t practically change the total burn time.
CD-RW 32x burn graphs
You remember that the Samsung SM-352N refused to process the CD-RW disc at this speed, limiting itself with 16x only. The new firmware of the AOpen drive only reduced the resulting time by 1 second.
I have nothing to say against any of the drives. I do not want to pay much attention to the TS-H492A’s pulsation as it was trying to accelerate suddenly. In fact, it only makes sense to compare the results of the COM5232/AAH and the TS-H492A, since the SM-352N is out of play with its 16x. The drives that wrote the disc at 32x behaved much alike to each other – they even hit the maximum speed at the same point.
