DVD selection, CD disc reading speed important?


After a series of price crisis, DVD drive the price finally dropped the price of most of the ideal bottom line, DVD has gradually become the preferred purchase. After all, at a lower cost in a freewheeling place (his home) to watch a high definition large for any person who is a temptation, a pleasure.

Now, people will not be for the application of DVD limited only play DVD discs, there is a large part of the application also reads the CD data disc. Because of the domestic economic situation, the configuration at the same time buy compatible CD-ROM drives and DVD-ROM is usually a "luxury" behavior. So, as to replace the CD-ROM drives DVD-ROM, in addition to playing DVD discs, the read data as an ordinary CD-ROM drive has become another important task. Therefore, people focus on the DVD performance should not only confined to the ability to read DVD, DVD read CD disc, game disc capacity CD should be used as an important assessment indicators.

Market, the same speed (16X) of DVD drives ability to read data CD, but not the same. DVD data disc CD-ROM read speed of the existence of large gaps. To occupy the mainstream market, 16X DVD drive, its ordinary CD-ROM CD-ROM maximum read speed from 40X to 48X range there, and now some brands such as BenQ, BenQ, 16X DVD CD-ROM CD-ROM drive of the maximum time take rate has even reached 50X.

At this point, some people can not help asking: upgrade from 40X to 50X, so a small speed difference, for the average consumer really make sense? I can assure you: there is, and this gap is very huge. Even if we just 16X DVD drive's maximum read speed of CD-ROM upgrade from 48X to 50X, the gap is enough to surprise you. Do not believe that we do a very simple arithmetic how? We assume a normal drive service life of 1,000 hours total, from 48X to upgrade to the 50X, a second theory, the drive can be read more than 300KB of data, more than a minute you can read 18000KB (300 脳 60) data equivalent to 17.6MB (18000 梅 1024) of data, one-hour drive can read 1056MB accumulated more data to the drive "honorably discharged" when more than 1056 脳 1000 = 1056000MB read the data, if each CD-ROM assuming a standard capacity of 650MB, as this District 2X speed increase, so that only drive in life, the more distributed a CD of about 1625 light and heat. Of course, this is an idealized figure, due to various reasons, to upgrade from 48X to 50X can not be theoretically 300KB / s performance increase, but for sure is that real life performance we have obtained the absolute In the idealized values of 50%, meaning that the drive in the "retired" when compared with the greatest 48X CD-ROM can be read at least nearly 800 more than normal data CD, such a large data for any consumer to that is a temptation. Thus we have to admit, DVD drive's maximum read speed of CD-ROM discs for DVD purchase is still very important.

The only regret is that it is able to support the largest CD-ROM read 50X CD-ROM 16X DVD drive is extremely rare. But there are exceptions, BenQ BenQ recently launched a model 1650S 16X DVD drive to have the greatest 50X CD-ROM CD-ROM read performance. In addition, it is worth mentioning also, BenQ 1650S also inherited the "crocodile family," the fine tradition: its overwhelming ability to read the disk, first-class product quality; with a second-generation "self-gear" technology, while maintaining strong operating performance also has good stability; with steel movement, super durable, even at high temperature and humidity of the harsh environment in normal operation may also be a long time; advanced dual-wavelength single data access technology shaved head, in reading different When the data disc can remove the cumbersome mechanical switch shaved head movements, not only significantly reduces the drive failure rate, it has raised the awareness DVD-ROM drive speed, DVD drive and therefore greatly extend the service life. 1650S can be considered a value of the all-powerful 16X DVD drive.

DVD-ROM CD-ROM be replaced with machines of choice will be a trend in the time of purchase DVD, to taking into account their ability to read CD disc, this is the case, with 16X DVD, but also have a super time disk, CD-ROM, why not?
