The ASUS DRW-24B1ST is a new drive for me. I’ve used ASUS DVD-ROM and CD-RW drives for years, but this is the first ASUS DVD writer I’ve tried. Usually, I stick with NEC (now Optiarc) or Pioneer. Actually, I’m in the process of testing the DRW-24B1ST right now by burning some Verbatim MCC-004 (my favorite) and some Philips CMC Magnetics AM3 discs. Put up against my Optiarc AD-7200S, it doesn’t look good for the ASUS drive. The ASUS came with 1.04 firmware which I’ve read is problematic. Tried to flash back to 1.03, but the ASUS winflash program apparently doesn’t allow you to flash back to a previous version. We’ll see.
