is an evolutionary replacement for the Parallel ATA
physical storage interface.
A selection of Serial ATA
products supporting 3Gbps signaling speeds have already been announced.
AHCI is intended to alleviate multiple controller implementations that traditionally fragment advanced capability development in traditional ATA
It will provide universal interconnect with Serial ATA
, while offering logical SCSI compatibility along with improvements in the reliability, performance and manageability of Parallel SCSI.
2) Scale to much larger capacities than parallel ATA
0 of the Serial ATA
specification, which will increase the bandwidth to and from disk drives--ranging from hard drives to CD-RW drives--and other PC components.
For enterprises with demanding applications, Samsung's new SpinPoint P120 Serial ATA
hard drives, the 200 GB SP2004C ($150 Estimated Street Price) and the 250GB SP2504C ($170) feature 3.
Perhaps the most significant difference between SCSI and ATA
is that ATA
drives are single I/O devices with a point-to-point protocol.
Over the years, performance of the ATA
bus has been stretched--from 33MB/sec to 66MB/sec with 100MB/sec looming close over the horizon.
SATA-Xactor is a complete verification solution consisting of Bus Function Models (BFM), protocol checkers, test suites and reference verification frameworks for the functional verification of any Parallel ATA
(PATA) and Serial ATA
During a read operation, the faucet represents data coming from the disk, while the sink is the buffer and the drain is the ATA
interface to system memory.
Furthermore, Southwest and ATA
plan to enter a code-sharing agreement that effectively increases Southwest's share of the market.
