I have one LG 22X Dual Format/Double Layer DVD±R/±RW + CD-R/RW Drive on my system.
In configurator builds you are offered a second drive as an option.
Also in packaged systems (i'm smart enough to stay away from those) they package 2 drives.
I see the need for only one all purpose read write cd/dvd drive.
Is there any reason or application need to have 2 drives on your system?
but at some rare times, i've had an open dvd (not finalized) and needed to get a file or install something using the second drive. Now with home networks and thumbdrives it really is just a convenience thing
Optical drives is one of the most under-utilize hardware on the PC. For most cases one is sufficient. It does nothing most of the time. I have an LG drive that can read/write from Blue-Ray to the Old CD-Disc. Thats all i need.
