Serial ATA prospects and implementation time
Motherboard maker roadmaps still often feature Serial ATA supporting solutions. Though most of such announces is expected only in the 4Q when SiS presents its SiS964 Southbridge with integrated Serial ATA support; and later, when VIA Technologies releases its VT8235 Southbridge with same capabilities. Intel plans to present its ICH5 Serial ATA product after the first half-year of 2003. So, before these chipsets appear motherboard makers will have to use discrete Serial ATA controllers. Now such products from Promise Technology, Silicon Image, and Marvell Technology cost about $7 each.
Despite the first Serial ATA motherboards will appear for sale already in July, makers forecast the new interface to widespread only after the appearance of integrated chipsets, i.e. in the beginning of 2003.
This year Serial ATA support will be featured mostly in high-end boards. For Pentium 4 these will be SiS648 and Intel 845G based motherboards. VIA KT400 and NVIDIA nForce 2 chipsets will be used for AMD platform.
