DVD playback on the SM-348 is crisp and clean, and the added shock protection makes the SM-348 very quiet.
Not only is the SM-348 fast, accurate, and cheap, but it's quiet to boot. This drive takes the speed crown for fastest combo drive out there. That price makes this drive very desirable for the budget minded, or those who want a solid inexpensive optical solution for their Small Form Factor or HTPC system.
