Intel ICH5 integrates two Serial ATA host controllers that provide you an even faster transfer rate of 150
Mbytes/second. The traditional parallel ATA specification has defined the standard storage interface for PCs
with its original speed of just 3 Mbytes/second since the protocol was introduced in the 1980s. And the latest
generation of the interface, Ultra ATA-133, has been developed further with a burst data transfer rate of 133
Mbytes/second. However, while ATA has enjoyed an illustrious track record, the specification is now showing its age and imposes some
s
erious desi
gn iss
ues on today's developers, including a 5-volt signaling requirement, high pin count, and serious cabling headaches.
The Serial A
TA pecification is designed to overcome these design limitations while enabling the s
s
media rate dema
nds of PC platforms. Serial ATA is to replace parallel ATA with the compatibility wi
adding performa
nce headroom for years to com
e
asy to ro
ute cables.
