A few weeks ago I did some research trying to find out if the 716A is the only 8 MB buffer drive. I couldn’t come up with anything - because frankly if you search for those keywords - you get a ton of pages about this drive.
Anyway - I had thought that there were two dvd drives out there that had the 8MB buffer. Am I wrong?
A HD hardware cache might reuse the buffered data over and over (depending on the application), whereas an 8MB buffer on an optical drive that’s moving 22MB of data per second while burning - data that’s not reused at all - doesn’t mean much when the buffer is only capable of holding .33 seconds worth of data.
On a (slower) CD-only burner, the 8MB buffer might have made a difference in the absence of BURN-Proof technology, but buffer size these days is largely irrelevant. IMHO the 8MB buffer is just a selling point.
