Difference between IDE and SATA | IDE vs SATA

This page compares IDE vs SATA and mentions difference between IDE and SATA. Both are different interface types which are used to connect storage devices such as hard disk etc. with system bus of a computer.

IDE Interface Cable

IDE cable

Following are the features of IDE interface cable.
• IDE stands for Integrated Rive Electronics.
• It has been introduced in the year 1986.
• It is known as parallel ATA.
• IDE drives are slower.
• IDE interface type does not support hot plugging.
• The different data transfer speeds such as 16, 33, 66, 100, 133 Mbps are supported.
• IDE data interface cable is ribbon like and has about 40 or 80 wires.
• The IDE cable length is about 18 inch.
• IDE has single cable to carry both power and data signals.
• IDE cable is wide and hence will not allow free air flow.

SATA Interface Cable

SATA cable

Following are the features of SATA interface cable.
• SATA stands for Serial Advanced Technology Attachment.
• It has been introduced in the year 2003.
• It is known as serial ATA.
• SATA drives are faster.
• SATA interface type support hot plugging.
• SATA supports data transfer at different speeds such as 1.5, 3, 6, 16 Gbps.
• SATA data cable is narrow.
• The SATA cable length is about 3 ft i.e. 1 meter.
• SATA has separate cables for data and power signals.
• SATA cable is narrow and hence will allow free air flow.
