SATA is the new standard welcomed by hard disk and optical drive makers. It has a data transfer rate of up to 150 MBps. Although it is advantageous over PATA, because of its 133 MBps speed PATA is not dead yet. High speed and limited number of slots call for the need of a
SATA PCI host adapter to convert the PCI slot into extra SATA slots. This is very convenient when you have a number of SATA devices.
These adapters come to provide high transfer rate, easier configuration and hot swapping capability. External SATA devices are becoming very popular and these host adapters will make use of them very easy. This won’t need any expensive SCSI drives for better performance.
