So far so good.
Lags when the system wants to access the disk especially when you put a new DVD or CD in there. But when it captures it, runs fast. The disk gets HOT when I take it out.
Burned a DVD+R Sony worked well on my DVD player (Magnasonic).

Bought two, one black one silver, both RMA'ed.
Neither would recognize any media if set as SLAVE.
One, set as MASTER, would only recognize disks if inserted after the program was open - inserting a pressed DVD would accomplish nothing. DVD-R's burned at 12x were the best I ever produced. But sometimes my computer could not find the drive at all.
Second one worked flawlessly for 3.5 weeks. Burned a near perfect DVD-R at 12x in 7 minutes, inserted another DVD-R that burned in 23 minutes in PIO mode (about 20 seconds between disks). Drive would only operate in PIO mode, even installed on another computer.
My NEC3520A is still churning out respectable quality disks after over 800 burns, think I'll look for another one on e-Bay.

Wasted 7 DVDs before concluding that DVD write function was defective on brand new device. During troubleshooting, NEC tech support said that Memorex and HP DVDs are not supported. Returned it back to store.
