the DVD burner the 1st one you linked Reads & Burns. so to be honest it really doesn't matter, both of them will read an OS disk its just 1 will be able to burn CD/DVD's also in addition to reading.
normally a Drive is a tiny bit faster in reading than a burner drive but out of personal experience i haven't seen any noticeable difference
usually any DVD/CD burner drive will both Read+Write so it doesn't really matter
unless you want a burner
k. thank you
cause i was tryin to connect the IDE cable to it and wouldnt fit and i was lyk WTF.
so wen i got my flashlite i saw it was for a SATA cable.then i went to the specifications an stuff ...long story short i thought i got the wrong one lol..
