I have two burners, an external Memorex CD-RW 52X and a Plextor PX-712A. The plextor is on my secondary IDE channel alone as master. The Memorex is obviously on a USB2 cable.
I burned a 600 megabyte file on a Verbatim 16-24X CD-RW first on the Plextor and then I repeated the burn on the Memorex. Between burns I erased the disk using Plex Tools.
Here’s what happened. On the Plextor the buffer fluxuated wildly going from 100 percent all the way down to 1 percent. The Plextor did not make a coaster but it did most of the burning at the low end, about 16X.
I erased the disk and reburned the same file using the Memorex. On the Memorex it burned at 24X and the buffer never dropped below 100 percent.
I repeated this again with the same disk with both drives with the same results.
This is pretty disappointing. I expected the Plextor to do a better job than the Memorex drive.
Does anybody have any idea why this is happening?
