SATA vs IDE or PATA -Difference between SATA and IDE or PATA

This page compares SATA vs IDE or PATA and mentions difference between SATA and IDE or PATA. This guide helps in selecting the right drive for your need either SATA or IDE (i.e. PATA) based on various factors.

SATA HDD and Cables


Following are the features of SATA.
• SATA is the short form of Serial Advanced Technology Attachment. Here AT stands for IBM's PC/AT. It is introduced in the year 2003.
• It is newer standard which supports higher speed compare to IDE or PATA drives. Hence SATA has almost replaced IDE devices in latest systems.
• It has large storage capacity.
• It supports hot plugging.
• SATA data transfer rates are upto 6 Gbps.
• The SATA cables are narrow, about meter long and are splitted into two based on power/data.
• SATA drives are directly connected to motherboard and do not need jumpers.
• SATA drives are less expensive in comparison to IDE.

IDE HDD and Cables | PATA


• IDE is also known as PATA or Parallel ATA. It is introduced in the year 1986.
• It does not support hot plugging.
• IDE supports data transfer rates are upto 133 Mbps.
• The IDE cables are wider, about 18 inches long and are ribbon like.
• It allows connection of more than one harddrives per channel. To do so, multiple IDE devices are chained using ribbon cable from one to next and so on.
• IDE are expensive compare to SATA.
