My Plextor finally kind of kicked the bucket about 3 months ago. It was just about 5 years old. My burn speeds has been really slowed. Nothing beyond a 1X when burning a DVD. Occassionally (once every couple months, within the last year of its life), my PC would hang at the post screen. Since the new drive I never had a problem with boots. So I attributed it to the failing drive.
Overall the drive served me well and was pleased. IIRC it cost me $180 back in the day.
Now I have an Asus SATA drive. This is actually my 2nd drive, the first being DOA from Newegg.
