SATA changed the legacy of ATA technology as the subsequent generationinternal bus interface for hard disks. The interface of SATA is more updatedthan ATA and gives serial architecture for faster speed than the older similar technology.SATA wires are narrow and could be up to 3 feet or 1 meter in length, whileparallel wires are much limited and wider to a length of eighteen inches or 45.7cm. With External Serial Advanced Technology Attachment,the SATA speed extends to encompass outer storage solutions.

While eSATA attains transfer rates thricethose of FireWire 400 and USB 2.0, it have 1 drawback. eSATA needs its power connector, not like the aforesaidinterfaces. On the other hand, it is an excellent option for external storage. Notlike FireWire and USB interfaces, eSATAdoesnÂ’t have to interpret data between the computer and the interface. This improvesthe speeds of data transfer, while saving PC processor resources and removingthe need for an off-load chip.

For motherboards that do not have an eSATAcable, a PCI or Peripheral Component Interconnect card could be bought and mountedin an available Peripheral Component Interconnect slot that will give an eSATA interface. Laptops can utilize anexternal eSATA device created for the PCCard, PCMCIA, or ExpressCard slot, depending on the notebook model. eSATA allows use of high-speed SATA drives forouter disk arrays, not only extending valuable storage estate, but enablingfast handy storage as well. eSATA’s swappablefeature makes getting disks from home to work, or from one PC to another.Administrators, marketing and advertising executives, IT techs, and gamers willfind this so beneficial.

SATA has reverse standards, w/ older hardware helping the standardexclusively. With new SATA iteration, speed raises. Original SATA/150, or SATA,has a speed of data transfer of 150 MB/s or Megabytes per Second. SATA/3Gbs or SATAII doubled the speed of 300 MB/s to 3 GB/s. This is sometimes referred to asSATA/300 as well. Some resources report that SATA/600 will be out in the marketby 2007.

When buying a bus card or an eSATA controller, makesure it assists the SATA standard needed by your hard disk(s). Hardware that assistsnewer standards is normally backwards compatible w/ older devices, but thereverse doesnÂ’t hold. An eSATA controller created for SATA/150, for instance, will not be capableto bear the faster speeds of a SATA/300 hard disk.
