cache is onboard ram
cd-r is how fast it burns r cd's
cd rom access time is how fast the drive reads cd's after the door closes
cd-r/w is what speed r/w disks burn @
dvd +r is how fast dvd +r media is burnt at, same if it has -r
dvd+r/w same as cd r/w and -r for mat ( not to be confussed with "r" cd's)
any of these are good
