C|NET schrijft in dit artikel dat er weer wat vooruitgang is geboekt door het Serial ATA Working Group. Als Serial ATA eind 2001 / begin 2002 in gebruik zal worden genomen kunnen harddisks, CD-RW's en andere componenten genieten van een bandbreedte van 1,5Gbit/sec, ongeveer een verdubbeling tov van de ATA-100. Daarnaast zal elk component een directe verbinding krijgen met de processor en hoeven we niet meer te worstelen met lompe IDE-kabels. Helaas zullen de extra kosten bij de lancering wel vrij hoog zijn waardoor de techniek eerst alleen in high-end PC's gebruikt kan worden. Binnen een tijdsbestek van 2 jaar zal de rest van de PC-markt aan de beurt komen.
The Serial ATA Working Group published the 1.0 draft of its specification, which will effectively double the bandwidth, or capacity for data, between disk drives--ranging from hard drives to CD-rewritable drives--and other PC components.[...] Serial ATA offers about twice as much bandwidth as the current Parallel ATA standard, known as ATA 100. Serial ATA's first incarnation, dubbed Ultra Serial ATA 1500, will offer a peak bandwidth or transfer rate of 1.5 gigabits per second.
"That basically equates to about 150MB of data per second," Ravencraft said. In comparison, Parallel ATA's ATA 100 offers a peak transfer rate of 100MB per second.
"It's important that the interface keeps pace and in fact stays in front of transfer rates from hard drives," said Tom Pratt, manager of storage technology for Dell's Peripherals Development Group. "Parallel (ATA) is running out of runway. The Serial ATA interface is very forward looking. It was created with a 10-year road map in mind."
[...] Serial ATA also will do away with Parallel ATA's familiar ribbon cables. These cables act as arteries for moving data between devices inside the PC. Parallel ATA ribbon cable is about two inches wide and can be only 18 inches long. The Serial ATA cables can be made up to three feet long, allowing for more elaborate routing, which would aid in creating cooler-running PCs. [break]Onderstaande tabel geleend van X-Bit Labs:
