After doin a few tests, here are the test results promised.
This is an image of Nero InfoTool showing the changes made by the V2.00 Firmware.
Transfer Rate of a Data CD using Nero CD Speed.
Burned an Audio CD using Nero Burning ROM at 52X.
Using the same Audio CD burned just now, tested transfer rate etc. using Nero CD Speed.
No Errors found using Cd Quality Check.
I don't find the CD-RW sounds any louder when burning and reading at 52X compared to 48X.
There is none noticeable speed gain when writing at 52X.
DAE Quality still 10.
Maybe it's nothing to be excited about but it's just nice to be able to write at 52X when you bought a 48X CDRW drive.
