The dvd used for this test is a datawrite yellow Ritek G04 4Xspeed dvd-r. The drive used was my Pioneer 107 with hacked firmware version 1.13 As you can see, the top of the dvd is a bright yellow with the Datawrite logo on it. Maybe it's just me but I think this is a fabulous looking disc but obviously not everyone is going to like the look of it. The burning side is classic Ritek deep purple. I gave it a very close examination under my halogen desk lamp and there were no marks or blemishes whatsoever. Neither is there any sign of dye leakage at the outer edge of the disc. All in all a very nicely made dvd-r. I ran it through Nero CD/DVD Speed to test the data transfer speed. The results are shown below. The top line is the data transfer speed. As you can see it starts of at 6xspeed and then increases to 8xspeed with a nice steady transfer rate right up to the end of the disc. [bold]Don't forget that these are 4xspeed dvd-r's[/bold] The bottom line is the rotation speed of the disc itself. As you can see it is a nice smooth curve from start to finish. I have burned hundreds of movies on these 4xspeed discs at 8xspeed and can honestly say that I have never had any coasters. I've never been able to say that with any other disc. The compatability is excellent, they play in my standalone dvd players and my Playstation 2 with no problems at all. All my movie backups are done with either Dvd Shrink, Nero Recode 2 or RB/CCE, depending on the size of the film and the mood I'm in. They are all burned to disc with Nero Express. I'm sure there are other dvd-r's out there that are as good as this or even better perhaps, but for the price, quality and compatability they are hard to beat. I'm waiting for some 8xspeed Bulkpaq's to turn up in the post for testing. I've never liked Bulkpaq discs as I've always found them to be complete rubbish, but as I'm getting them for free directly from Bulkpaq for testing I thought I'd give them a go. Do you think I've got too much time on my hands?
