This is the first Plextor's combo drive. And it ships only in the Retail version. The drive comes with a user manual, cables and screws, 2 blank CD-R and CD-RW discs, and a CD with various programs. Here you can find two popular technologies Burn-Proof (buffer underrun protection) and PowerRec-II (for highest possible quality at the maximum speed). Besides, they promise the highest audio track extraction speed with the respective quality. Moreover, Plextor states that the black color of the tray reduces C1 errors and a jitter level. The design is austere, with just few buttons but with good indication. 

Nero CD-Speed

  • Vendor : PLEXTOR 
  • Product : CD-R PX-320A 
  • Firmware version : 1.01 
  • Buffer size : 2048 KB 
  • Maximum read speed : 7056 KB/sec (40 X) 
  • CDDA accurate : yes 
  • Read R-W : yes 
  • R-W packed : yes 
  • C2 pointers : no 
  • Speed settings : 4-8 X 
  • Read RAW mode : yes 
Well, I think we should stop using the Nero CD-Speed utility as it gives wrong data quite often. In this case it defines incorrectly some speeds and the C2 error correction. 

Nero InfoTool

The Plextor's drive is supplied with a utility which gives complete information on the drive and allows adjusting some parameters of operation. 

The screenshot shows that the utility is able to control even speed modes of the drive. 

Nero - Burning Rom

The drives supports such a useful function as buffer underrun protection. Besides, it's able to overburn discs. 

The drive is RPC-2 from the very beginning and it's impossible to turn it into RPC-1.
