Does 20x certified media even exist? I could have sworn that people said 18x would be the fastest. I wonder if Plextor will follow with a 20x. How many seconds does this shave off of the burning time? .7?

I call BS. How can it write faster than it can read?

Does 18x CM even exist? I haven't been paying attention but assumed it required over-burning 16x'ers. Anyhoo, if 16x takes 6min then a rough approximation for 20x would presumably be 6(16/20) = 4.8min or aboot the same 1min difference for the 4x betwixt 12x & 16x. So perhaps 30sec betwixt 18x and 20x, all things being equal and ideal. <- don't mind if I help myself

CMC, Ritek 18x DVD Media Production Limited

Although several leading global brands have already launched or will soon offer 18x DVD burners, CMC Magnetics and Ritek, Taiwan's top two makers of optical discs, currently produce 18x DVD+R/-R discs only in limited volumes.

Plextor, Lite-On IT, Samsung Electronics, LG Electronics, Sony, NEC and BenQ currently offer 18x DVD burners while Pioneer and Asustek Computer will do so soon.

However, the global supply of 18x DVD+R/-R discs appear to be lagging. CMC and Ritek are able to immediately start volume production of 18x DVD+R/-R discs as long as the market demand is large enough, the two companies said.

However, because of relatively high prices, 18x DVD+R/-R discs will not become popular until 2007.

===========================

Sony 16X, miflop (TYT03/G03 16X +-R), Verbatim 16X, TDK (actual) all burn at 18X @ ~5 1/2 Min.
Looks like TY G03 16X (-R) does about the best

I guess if you want to future proof yourself you could buy one when they become availble. Question is... do you need one that has no avalble media to take advantage of the speed? I could see buying them if they are the same price as the current models but if they are more expensive what good are they if they aint got the media to use with it?

 

[LikeLinus]

I use Verbatim 4x medium in an 8x and 8x in an 16x before. I'd imagine you could use 16x good quality DVD's in a 20X.

i always burn at 1x anyways, just to get a deeper burn. dvds won't play on one of my dvd players if i don't.

I'd be more interested in a SATA LiteOn (or NEC, Benq, Samsung, etc.) DVD-RW drive.

You need better media or a better burner. There should be no reason to burn that slow.

No doubt.

I thought that 16x was the physical limitations of the rotational speed with a singal lense. Anyone know the physics behind this?

the physical disc speed has not incresed, just very sophisticated trick burning strategy in the firmware

Exactly. DVD media is not like CD media. DVD-Rs need to use a totally different write strategy for 4X+ burns than they do for 1X and 2X burns. The concept of a "deeper burn" at 1X doesn't even make sense. For example, older burners were incompatible with 4X+ media, and using that media could actually damage the burner unless you got a firmware upgrade to give the burner the proper write strategy for faster-reacting dyes. The "deeper burn" you got would make a coaster and damage the drive.

You can see that the highest speed burns do give slightly more soft errors, but this is fairly inconsequential. The difference between a 4X burn and a 16X burn isn't much, but the difference between a 16X burn with quality media vs. a 16X burn with trash media is huge.

So if you're concerned about burn quality, get Taiyo Yuden media and burn it as fast as your burner will let you.

I seriously doubt that, and if you have any information to back up your statement I'd love to see it.

Lite-On is not claiming there is any "sophisticated trick" to speed things up, and the only thing I can imagine that would actually help would be a Kenwood True-X-esque multi-beam laser, which would be quite sophisticated indeed for burning.

Keep in mind that this is 20X MAX. CD's are good up to 10,000 RPM, but most places will tell you that a DVD (which is heavier) shouldn't spin more than 9,500 RPM, and even then you have to be careful that you don't have a label on the disc or anything when you're going that fast. A DVD drive running at a fixed (CAV) 10,000 RPM is going to give you about 6.5X on the inner track and about 17.5X on the outer track as I recall. Spinning faster than that can be accommodated somewhat by the drive having a good vibration dampening mechanism, but is heavily dependant on well-balanced quality media.

I mean, having a DVD burner faster than a 10K RPM hard drive is a little crazy.

My Old single layer 8X burner finally took a crap on me after several years of solid service so I went to newegg to replace it. They had the Lite-On LH-20A1H-185 20X burner for $39.99 versus $36 shipped for most other 16X or 18X drives from Lite-On, Samsung, NEC, and Benq. I spent the extra $3. The LH-20A1H-185 also has lightscribe and 12x DVD-Ram burning so I felt it was a no-brainer. Should be here in a day or two so I'm looking forward to trying it out.

I know 20x burning is overkill especially considering there is no media available but I guess it won't hurt to have it.

Anyone try out the LH-20A1H-185 yet?

i bet this will make a ton of noise. i wonder how high the disk shatter rate will be.

LOL. I guess burning at 20x DVD would be similar to burning a CD at around 80x. Didn't mythbusters once do a test on this only to find out that the disks would only shatter if exposed to rotational speeds much higher than what DVD/CD players could do?

I'll let you know how noisey it is once I get it.

 

[coomarlin]

Anticipating the drive I got online to download a manual and any firmware updates I might need. lol Wouldn't you know Lite-ons website blows hard and I can't find a manual or firmware anywhere. Not that I really expected any different but I've heard both good and bad things about Lite-ons. I've never owned one.

Any sites out there that are for lite-on owners?

cdfreaks and rpc1.org are good.

Indeed. I just found a few really good threads there to read. I installed the drive last night but I don't have any media certified to burn at 20x. I burned a few things at 16X and did a little lightscribing which worked better than I expected. I'd like to do some benchmarking but I'm still trying to figure out how to use CD/DVD speed.
