IDE and also SATA are different varieties of interfaces to affix storage devices (like tough drives) come a computer"s device bus. SATA represents Serial Advanced technology Attachment (or Serial ATA) and also IDE is likewise called Parallel ATA or PATA. SATA is the more recent standard and SATA cd driver are quicker than PATA (IDE) drives. For many years ATA listed the many common and also the the very least expensive interface for this application. Yet by the beginning of 2007, SATA had actually largely replaced ide in all brand-new systems.

The ATA user interface (ATA stands for AT attachment wherein "AT" describes IBM"s PC/AT for which the was originally built) evolved in step from western Digital"s original integrated Drive electronic devices (IDE) interface. ~ the introduction of Serial ATA in 2003, the initial ATA was retroactively change the name Parallel ATA.

Comparison chart

ide versus SATA comparison chart IDESATAAdvantages Disadvantages Hot plugging (add/remove ingredient while the computer system is running) Speed Data cable Lineage Year produced Jumpers
Maximum compatibility Inexpensive, big storage capacity.
Lacks support for brand-new technology together as native command queuing and also hot-plugging difficult drives Lower MTBF than SAS (700,000 hours to 1.2 million hours of use at 25 °C), less suited because that servers.
IDE interface does no support warm plugging SATA user interface supports warm plugging
data transfers at the price of approximately 133MB/s Data transfers at the price of up to 6 Gb/s
Ribbon-like, wide, have the right to be approximately 18 inch long Narrow, deserve to be up to a meter (roughly 3ft) long. Power and data split into 2 connections.
Superseded by SATA Supersedes Parallel ATA (PATA) aka IDE

In a computer system system, it"s feasible to have more than one harddrive. To affix multiple concept drives, you should chain the ribbon cables from one come the next. The computer system has no idea i m sorry is the main drive, from which to fill the OS. SATA cd driver don"t use jumpers. Each journey connects straight to the motherboard. To set the major drive, girlfriend can accessibility the settings from the computers BIOS (special software program that runs as soon as you start the computer).



SATA (right) and also IDE (left) tough drives. The SATA hard drive has actually the data cable top top the right and also power cable ~ above the left. The concept data cable is ribbon-like (on the left)

Hard drives need a cable/connection for data and also one because that power. Parallel ATA only enables data cable lengths up to 18 in (457 mm) when SATA allows cable lengths approximately 1 m (3.28 ft). ESATA cables can be 2 m in length.

IDE is composed of a 40-pin connector attached come a ribbon cable. 80-pin connectors were additionally introduced later. The connectors space black in a 40-pin connector if in an 80-pin connector, castle come in 3 colors: blue - controller, gray - servant drive, and black - understand drive. Each cable has actually two or three connectors, one connector is attached come the user interface that connects come the computer system system (mother board) and the others are linked to the drives.

SATA consists of an 8 mm broad wafer connector on every end and the cable has a 7-pin connector, 3 grounds and 4 energetic data lines in 2 pairs. It has the facility to affix only one drive and also so Serial ATA does away v Master/Slave configurations.


This video clip explains how to readjust the hard drive on a desktop computer computer; it additionally shows the differences in between SATA and IDE connector cables.

Adapters and Integrated Motherboards

You have the right to buy incorporated motherboards that enable a computer to usage both SATA and IDE tough drives. However, only one of the two may be supplied at any type of given time and also both can not be supplied simultaneously. Adapters are also accessible that permit an ide drive come be provided with a SATA motherboard and also vice versa. These IDE/SATA adapters mask the underlying difficult drive and also simulate its functioning to enhance the expectation of the computer"s motherboard. Lock usually expense less 보다 $15.


Two different of SATA - eSATA and eSATAp - are available. ESATA is supposed for external connectivity. ESATA can not supply power from the motherboard to the hard drive. In bespeak to get rid of this limitation, eSATAp drives to be introduced. ESATAp harbor combines the stamin of both eSATA (high speed) and also USB (compatibility) right into a solitary port.


Data transfer speed for concept ranges native 5MB/s as much as 133MB/s (ATA100/133). The parallel cable transfer mode reached its limit with the rate of 133 MB/s.

SATA took off wherein ATA stopped as far as rate is concerned. The very first generation that SATA to be 1.2 Gbit/s (150 MB/s; keep in mind that MB is megabytes and Gb is gigabits) comparable to PATA/133. This particular day the third generation of SATA (3.0) (released on might 27, 2009), 6 Gbit/s (600 MB/s) difficult drives and also motherboards space being used.


Air flow

The wide wire in concept cables resulted in airflow difficulties inside the case. The narrower SATA cable allows totally free airflow within the case.

Hot Plugging

SATA cd driver have second feature of warm plugging which average that even as the computer system is to run drives deserve to be gotten rid of or added.

Power Consumption

PATA (IDE) drives require 5 volts and 12 volts in desktop form factor.

SATA drives use 5 & 12 volts & "can" encompass 3 volts also

but practically all existing disk drives execute not use the 3.3 V line.

Master/Slave Configuration

SATA has additionally done away v the master/slave configuration (technically, device 0 and maker 1) used in ide drives. With PATA (IDE), attaching two tough disks come the same channel required one come be set to it is in the master, the various other the slave. For hardware, this typically meant setup the right jumper settings.

But the SATA bus is a serial point-to-point bus, which method only one an equipment can be connected on every channel. Many SATA cd driver can connect to the motherboard via many ports, and also the journey to boots from is mentioned in the BIOS settings.
