Advantages of Buffer Underrun Proof
Technology
PlexTools Professional software lets you enable or disable Buffer
Underrun Proof Technology on the Plextor PX-716UF (via Drive
Settings | Advanced). But you’ll usually want to leave this feature
enabled, because Buffer Underrun Proof Technology guarantees that
you can write discs at high speed, and still use your computer for other
tasks while you’re writing.
To prevent the interruption of data during writing, every CD-R/RW
drive has a buffer, a memory chip that acts as a kind of “holding area.”
(Typically, the buffer size is 2 to 8 megabytes.) However, this buffer can
be emptied quickly when you write at high speeds, or if you use other
applications (like surfing the Internet or playing games or watching
movies) while writing.
Buffer Underrun Proof Technology compensates for any interruption in
data flow to the disc. It “remembers” where writing stopped on the disc
when the data flow was interrupted, then restarts writing in the same
place once the data is available again. Buffer Underrun Proof
Technology in your drive means you can safely use your computer for
other things while you’re writing to a CD-R or CD-RW disc. It lets you
multitask freely and easily, and lets you successfully create CDs on the
first attempt.
