Table 1 provides an overview of the average performance for copying files to and from the DVD-RAM drives tested and compares these results to similar results of copying and pasting files within Compaq's hard drive. Since the drives supplied were pre-production models, I felt that a comparison test was not indicative of the final drive's performance. I used CBI's Removable Benchmark software to determine the time to copy and paste various sized Microsoft's Word 97 data files.
For file sizes of 2MB or less, copying data from the hard drive to the DVD-RAM provides similar performance to that of a hard drive. The performance of the DVD-RAM diminishes to about 35 to 40% of the speed of the hard drive for file sizes lOMB or greater. The data transfer rate is still respectable for the DVD-RAM for storing these larger sized files. The average size of a file to be stored for personal or corporate use may be less than lOMB anyway so the DVDRAM should suffice for those who are speed hungry (Table 2).
For those applications where data can be initially...
