First, the SATA standard has reduced the wires needed for connection from the IDE’s thick cables down to an 8-pin connector. This eliminates the need for the bulky cable and also improves overall PC cooling efficiency allowing better air circulation inside the casing. The other and most enticing difference is the ability to hot-swap meaning hard drives can be replaced without having to turn off the power of the computer system as long as there is no read/write operation in progress.
There is only one other hard drive framework that can surpass the higher speeds of the SATA standard which is SCSI, a technology that has been around for along long time that has undergone several revisions. The SCSI technology is however very expensive for the higher speeds require more precise engineering thus still limited to use in servers and expensive systems where reliability and robustness is an issue. Sata has long replaced the IDE standard due to the high speed advantage but other than that, they still share the same function, data storage. Newer ultra-portables use flash drives to save on power for hard drives are still quite demanding on the power supply. Advances in solid state memory and expansion into the realm of the gigabyte allows them to serve the same purpose as their electro-mechanical counterparts.
