The M5721 features 20x read speed and integrates a servo chip and RF amplifier, allowing DVD drive makers to add only external DRAM, flash ROM and a power controller, significantly reducing the circuit design complexity and cutting production costs. ALi said shipments of its combo chipsets, supporting 48x and 24x CD-RW write and 16x DVD-ROM read speeds, are small, between 3,000 and 5,000 units a month. The company expects monthly shipments to grow to 30,000 and 50,000 units a month beginning at the end of the year. According to industry sources, Samsung Electronics is using ALi's chipsets in its latest combo optical storage drives. ALi said it has priced its chips and chipsets according to the market standard. It reiterated that it will not slash prices to be more competitive. Currently, 16x DVD-ROM chips cost US$7-8 and combo drive chipsets US$12-15. |

The easiest way for manufacturers to double the DVD-ROM speed is to use dual laser pickup. I seen dual laser 72x CD-ROM drives a while back priced just a little more than 40x CD-ROM drives!
