The Plextor PX-716A is Plextor's first DVD recorder to support dual layer recording. At the moment the PX-716A only supports DVD+R DL media but via a firmware upgrade the drive will also support DVD-R DL media in the future.
Disc 1 - Verbatim 2.4x:
---------------------------------------------------------- Unique Disc Identifier : [DVD+R-DL: MKM-001-000] ---------------------------------------------------------- Disc & Book Type : [DVD+R DL] - [DVD+R DL] Manufacturer Name : [Mitsubishi Kagaku Media] Manufacturer ID : [MKM] Media Type ID : [001] Product Revision : [Not Specified] Recording Speeds : [1x , 2.4x] ----------------------------------------------------------
As you can see from the PI/PO scans our first disc was written perfectly. Also note that the dual layer Verbatim disc (manufactured by Mitsubishi) was certified for 2.4x recording but the Plextor PX-716A had no problems writing it at 4x.
Disc 2 - Traxdata 2.4x:
---------------------------------------------------------- Unique Disc Identifier : [DVD+R-DL: RITEK-D01-001] ---------------------------------------------------------- Disc & Book Type : [DVD+R DL] - [DVD+R DL] Manufacturer Name : [Ritek Corp.] Manufacturer ID : [RITEK] Media Type ID : [D01] Product Revision : [001] Recording Speeds : [1x , 2.4x] ----------------------------------------------------------
Our second and last disc we tested had a bit of a problem on the second layer (after the 4GB mark). As you can see from the scans the first layer of the Traxdata/Ritek DVD+R DL disc was written perfectly but the second layer shows high SUM1 values right after the layer break. So, is the disc a coaster or still readable? Let's find out:
As you can see the Plextor PX-716A could still read the disc after it was burned but it did slow down to only 2x when reading the second layer. So all in all not a very bad result but not a good one either. Let's continue to the drive's DVD-R/RW performance.
Writing DVD+R/RW
The main conclusion about it for me is to not worry about the innovative technologies PowerRec, AutoStrategy, VariRec, (which was not reviewed), and just give it what it craves, Taiyo Tuden 8x +R and it burns and reads with the best.
but it looks nice hmm :/
Isn't that what the powerec is for; to improve quality at a small speed penalty? You're missing the whole point here.
Mt Rainier not supported. Oh my Gosh! Now I will certainly never-ever buy this drive. Come on, who cares...
he said that when disabling PowerRec, there was no decrease in quality
didn't you read the review????
