24x DVD burners hit the market
There is some uncertainty on which will be the one, between Sony Optiarc and Lite-On, to market the first drive of such kind, but the fact is that DVD burners will once again exceed the maximum write speed limit going from 22x to 24x. Both companies will release the new optical drives between March and May, and though in practice the speed difference isn’t amazing at all, the new breakthrough shows that firms continue to invest in a technology with a surprisingly long life.
In the never ending wait that the Blu-ray format turn into the hit the majors hope for, DVD as a data storage medium hasn’t concluded its race yet: far away are the times in which it was stating that 16x was the maximum achievable physical limit for optical disk burners, and after exactly a year since the 22x ones that limit is now ready to be exceeded by 50%. The first company to announce the release of the new drives is Lite-On, which will market the models iHAS324 and iHAP424 in March and the model iHAS624 in May.
The three burners, which have in common the same 24x writing speed “on select media” (supposedly certified DVD±R disks), differ for features and the communication interface with the motherboard: iHAS324, available in the middle of March, is a Serial ATA (SATA) drive featuring the SmartErase technology to permanently erase disks containing “confidential data“; iHAP424, on sale at the end of this month, features a Parallel ATA (PATA) interface, SmartErase technology and LightScribe to write labels on disk with the laser; iHAS624, at last, will be out within the middle of May and will bring a SATA interface, SmartErase, LightScribe and the new LabelTag feature to “create a label ring on the data side of any standard recordable media“, according to Lite-On press release.
Sony Optiarc’s announcement came after the Lite-On one, nevertheless the Japanese giant subsidiary clearly states to be the first company in the field to market a 24x DVD burner in March. Defined as a “high speed miracle“, the AD-7240S drive writes compatible DVD±R disks at 24x while the maximum speed for DVD-RAM and double layer disks is 12x. The drive features the “Auto Strategy Technology”, to optimize the writing process by analyzing the next part of the disk while burning, and the “Adaptive Self Tuning” technology which constantly monitors disk and hardware to compensate the possible fluctuations within the data flux to write.
Putting aside the debate on which company deserve the title of “first manufacturer” of 24x burners in the world, math says that such speed equals to a data bandwidth of 32.4 Megabytes per second (1.35 x 24), that is to say slightly less than 3 minutes for a single layer disk burning. Or at least theoretically, because in practice the entire burning process generally takes some minutes more (4.5 on a good 22x drive).
Being the time gain already very slight going from 16x to 18x (4 theoretical minutes against 3 for a single-layer disk), the release of 24x burners isn’t an occurrence that will be remembered as a fundamental technological breakthrough. Then there must be considered the counter-indications in pushing so hard on the data writing process with optical disks, where a speed increase is directly proportional to the likelihood that the burnt medium will get flaws and a high C1/C2 errors level.

And where would I be able to get such disks? And how much more would they be compared to 16x disks?

DVD? Who cares?

Almost 75% of the world population still cares about DVD’s as the blue ray bullshit is too expensive and too few; except of course who do not mind blowing up a fortune for Sony sucking technology.
