Plextor PX-891SAF

[QUOTE=corso;2768401]I’ve just purchased a Plextor PX-891SAF. I must burn many audio CDs. Which speed is the best? I need to prevent the degradation over time. Theoretically, the lower speed the better, but in the specifications that [B]Imgburn [/B]shows, apparently the lowest speed is 16x. Is it possible to burn at slower speeds just selecting them manually? Is it worth?

If tests must be done to determine the optimum speed, how? I see in this thread that [B]Nero cd-dvd speed[/B] is used to make dvd tests, but I don’t know how to start or how to understand the graphics. Does anyone know a tutorial for this?

Besides the speed is there anything else I should consider?

Thanks[/QUOTE]

Welcome to the forums, corso!

I did some burns with this drive using a very good CD (JVC = Taiyo Yuden), as shown above. 16x is the slowest speed this drive burns this particular disc at; you won’t achieve a slower write speed in ImgBurn by specifying a slower speed, since the writing speeds are controlled by the firmware. The results look pretty good at 16x and 24x, although jitter is a tad high. Above 24x jitter seems too high to me. If you’re using a lesser quality CD, your results won’t likely be as good as the ones above. In summary, you should be ok burning at 16x or 24x with good quality CDs, as long as you let the laser cool down (~15 minutes) between burns.

There are numerous tutorials around the forums on using CD-DVD Speed for scanning discs. If you’re interested, check out the Disc Testing & Methods forum.

Thanks! I guess I will burn at 16x speed. The burning time is not so important if I should wait 15 mins. between burns.
I don’t know if my CDs are good or not. They are Maxell, with the RFD80M-79875 reference in the inner circle, but ImgBurn shows Ritek. Co. as manufacturer.

I don’t have any Ritek CD-Rs, but if you post the MID that ImgBurn (or Nero) shows, perhaps someone here has used them and can tell you how good they are.

By the way, you cannot prevent degradation over time by selecting a slower speed. The only thing you CAN do is help the initial write quality to be good, which means early stages of degradation might not affect reading as much (plus a disc written well is easier to read in general)…

But I think modern Ritek CD-R have a moderate life span, so degradation is not a huge deal for day to day use (and storage in proper environments allows the discs to last quite a few years, assuming the discs themselves are good).

(Note: I do not have this drive, so I cannot speak for its write quality on any media.)

Thank you for the information. I didn’t know that MID thing identifies the CD model. It is:
MID: 97m15s17f (Ritek Co.).
In a quick search I found this thread:


I can’t understand the graphics but the evaluation that RJL65 made nine (!) years ago seems good to me.
I bought those CDs 3 years ago and I stored them well, but I’m afraid those CDs are too OLD. Is this a problem or the clock starts the day they are burned?

Recently (12 \ 2015) checked Maxell CD-R Ritek mill recorded a few years ago. For this album the whole time used in the car and quite badly scratched.
