Forty-Speed CD-RW Shootout
Keefe John writes: "Several months ago, 40x burning became a reality when Plextor got the jump on all of the other optical storage companies with the PX-W4012TA CD-RW. Since then, many companies have been coming out with versions of their own. As with any genre of products, a few stood out above the rest. Namely, the original tried and true Plexwriter; the wallet-friendly Lite-On, and the speed-daemon Teac. Today Techware Labs will be comparing the three drives on their relative merits. Read the full review over at Techware Labs."
I got this plextor drive shortly after it came out and amazingly, it is QUIETER than the 24x10x40! If you are looking for pretty quiet CD-Rw, I say you should check the plextor 40x12x40 out. Furthermore, the slower one has a fan on the back and mine does not! (Try to get the European version, btw, because it comes with Nero as opposed to Roxio EasyCD.0
To be technically correct, they have a MAX speed of 40X. They don't burn at that speed throughout the entire burn, they may reach that speed at some point though. That's why the actual burn time of a CD has pretty much reached it's limit. Going from 8x to 16x is not the same as going from 16x to 32x.
My beliefs do not require that you agree with them.
As others have mentioned, Plextor does. I believe there are some Toshiba models still available too. Just do a search on Pricewatch and you'll see who has what. I know that Newegg carries the Plextor.
Of course, you'll pay a hefty premium ($50 more for the Plextor SCSI, or 300% compared to Lite-On, Cyberdrive, or other inexpensive CD-RWs) and get a much slower drive (12/10/32 vs 40/12/40 or 40/12/52).
Unfortunately you don't have any choice in the matter for your instance. But people building workstation PCs with all SCSI are (by and large) just screwing themselves now.
Burning a 4.7G data DVD-R on my Pioneer DVR-A03 takes about 45 minutes.
Not to nitpick but dude if you're going to get 1000 cds burned instead of stamped your getting hosed.
costs for 1000 cds burned will 640 bucks bullk, ~1200 w/ packaging(full retail). does it, and no i don't work for them just used them
As I recall, each speed increase turns out more frisbees than the last. 10x burns less reliably than 8x, etc
If you have a first-generation crappy drive, or use media that isn't designed for that burn speed then that's true.
theoretical maximum number of CDs they can burn
Yes, and HD's have a theoretical average number of hours before failure. So? All mechanical systems fail at one point or another.
yet to see a CD-R rated for more than 24x
You haven't looked recently, have you? Try here, or here, or here.
Plextor at least (apparantly) won't let you burn at a higher speed than the CD-R(W) is rated for
That's dependant on the software, not the hardware. I know you can turn it off in Nero, and probably most other CD burning software.

- Although the maximum reading speed of the drive is 48x, it will be factory set at 40x and includes a SpeedRead function that enables users to select the higher speed.
Oh, the burnmanity!Patrick Peeters explains: "The reason we use this unique approach is to provide flexibility to customers: for the vast majority 40x is the ideal mix of speed/quality, but there are a small number that will require 48x. However, the increase in speed from 40x to 48x can increase the noise for any drive in the market. In extreme circumstances using high-speed reading, where the CD is severely scratched, it can explode in any drive and even cause injuries to the user. We have redesigned the PlexWriter 48/24/48A drive to strengthen the front bezel to prevent any injuries. To our knowledge, we are the only manufacturer in the market to have implemented this safety feature."
Money for nothing, pix for free
Whatever about saving that precious extra 30 seconds or so during burning, I prefer to know that my burner can handle some of the more neferious copy protection schemes now coming to market.
Many of these are based on sending abnormally regular EFM subchannel data to the CDRW and relying on it to crap out. You can get details about the capabilities of current burners here, but this CloneCD list describes exactly which burners have the firmware "Correct EFM-Encoding" cojones to defeat the latest copy protection.
I'm glad to see that the "wallet-friendly Lite-On" drives seem to feature some of the the most consistent support for defeating EFM trickery.

The aluminum is nothing more than a reflective layer; the data is molded into the plastic.
Having said that, you're absolutely right that it would be very unlikely that a CD-ROM drive could produce enough heat to damage the disc.
The point about the CD-R's is mostly correct, however they don't burn the dye away. The dye just works to absorb certain wavelengths from the write laser. All CD-R's come with a smooth (well, mostly smooth; it does "wobble" a little for time coding, etc.) groove instead of a spiral of pits. When the dye in a certain area has heated enough, it deforms the groove, causing a read laser to have a slightly different return at that point. In essence, it becomes a "pit". Since the dye only acts on specific (infrared) wavelengths, the discs are fairly robust; however leaving one in the sunlight for a length of time is guaranteed to destroy it. It is doubtful that a drive could produce that kind of radiation in any meaningful amounts.
BTW, one thing that is rarely mentioned about really fast burners is the write laser power output. It is one of the reasons that burning doesn't go faster; not because of limitations in the substrate.
Sorry for the rant.
