1GB CD-RW Drives: Take a Pass
Capacity boosted by new technologies, but speed and compatibility issues abound.
Do you like the idea of squeezing a gigabyte of data or more onto cheap CD-R discs that usually hold only 700MB? I did, but my enthusiasm waned quickly after I tried drives incorporating a pair of new CD-recordable technologies developed by Plextor and Sanyo.
Plextor's GigaRec technology, found in the company's latest 52X/32X/52X Premium drive, increases the capacity of CD-Rs while also trying to maintain compatibility with other drives that can read CD-R discs.
GigaRec audio and data discs played fine in firmware-updated 40X and 48X Plextor CD-RW drives, but worked with only modest levels of success in non-Plextor drives and home CD/DVD players. Unfortunately, GigaRec disables buffer-underrun protection, too, and writes at a painfully slow 4X, or 30 minutes per disc.
Sanyo's HD-Burn is another CD-writing technology, but it debuts on the OptoRite DD0203 drive, which supports DVD+R/RW and DVD-R/RW. HD-Burn technology can pack data so tightly that only DVD or DVD/CD laser assemblies can read or write it--after a firmware upgrade. Its lack of compatibility with the vast installed base of CD equipment aside, my tests showed that HD-Burn doubled the capacity of normal 700MB CDs to 1.4GB and wrote far faster than the GigaRec drive did--24X on the OptoRite unit with buffer underrun protection.
