Parallel ATA (PATA), formerly known as Integrated Drive Electronics (IDE), is a standard interface that enables communication between the motherboard of a computer disk drives. PATA is mainly used for controlling hard drives and CD-ROM drives. It makes use of the underlying AT Attachment and AT Attachment Packet Interface (ATA / ATAPI) standaarden.De name of the IDE interface refers to the way the IDE drives are designed.

For each disk drive, there must be a control system or disc drive controller in order to send to the station. For IDE drives, this control system in the station itself built. Vandaar de naam Integrated Drive Electronics. The connection to the motherboard (formerly mostly on an expansion card) controller is often called, but that is actually not accurate, because the controller is located on the disk drive itself. Previously, most motherboards have two IDE connectors, but modern motherboards have only one, because the new Serial ATA standard.

Master/slave

The terms master and slave are US rather controversial. Although they do not occur in an official standard, has the computer industry for a long time, they embraced. However US court rulings that, where possible, preferred is the standard designations device 0 en device 1 using. PC architecture: CPU — FSB — Northbridge — RAM — AGP — Southbridge — PCI — USB — SATA —PATA It is possible to connect together two disc drives. One station will be with jumpers set as master and the other as slave. De controller van de slave is uitgeschakeld en de controller van de master bedient beide stations. Connected to two masters and two slaves on the same cable, then a conflict occurs so that the stations can not work. For older disk drives, the jumper settings were often:

• Master - Slave not present

• Master - slave present

• Slave

In modern drives no longer need to specify with jumpers or a slave is present. Indeed, set as a slave station also works if there is not a master. In modern drives there is an extra jumper setting, namely 'cable select'. The settings are then:

• Master (BUT)

• Slave (SL)

• Cable select (CS)

If one uses the last setting, then a special cable must be used to determine which slave station or master is. It is thus not possible to connect two masters or two slaves on the same cable. It is still important that both jumpers to CS stand. The special cable is recognizable by the color of the connectors:

• blue: Motherboard

• black: master

• gray: slave

Imagine you use one drive as the master and the other as slave then it is not important what kind of cable.

Naming

The IDE standard was in 1990 accredited by ANSI. ANSI, however, does use a different name to indicate the standard. The ANSI standard corresponding to IDE, hot (parallel) ATA of Advanced Technology Attachment. Links:7-pin cable for serial ATA Top right:15-pin power connector for serial ATA and Bottom right: a PC power supply with both classic four-pin Molex power connectors (colored white) as a SATA power connector (colored black). The large white ATX power supply connector is a connector which is not related to this article. Serial ATA (ook SATA of S-ATA) is a computer bus designed to transport data between the computer and the hard drive or DVD / CD player. Serial ATA is de opvolger van Parallel ATA/PATA/P-ATA (Advanced Technology Attachment) of IDE-bus.

Feature

The first generation comes from 2003 in (SATA150) worked with a maximum throughput of 1,5 Gb/s. In 2004 a new generation was (SATA II/SATA300) developed that the throughput increased to a maximum of 3 Gb/s. It was expected in 2007 a new generation (SATA III/SATA600) that would increase the maximum throughput of 6 Gb/s. However, this was postponed until the end 2008. In July, the first preliminary version ready. From 2010 deliver the first motherboard manufacturers, Conventional hard disk drives and solid state hard drives with onboard SATA600. Serial ATA uses cables narrower than the ribbon cables of parallel ATA, which leaves more space in the computer case. This is favorable for the cooling. The cables can also be connected not reversed, as with many older IDE cables was the case. There is no longer a shared bus such as IDE. As a result, there is no distinction between master and slave. The power cables for ATA drives are also different and more compact. Additional differences with the conventional connectors are Molex: 5 pins for the purpose of the ground to the total recycle stream (up to 7.5A; 1,5A per pin/ader). An additional voltage of 3,3 volt (distributed over 3 pins, also in order to be able to meet the overall power demand). A hotplug a voltage detection pin that is longer than the other (en de ground) so that it makes insertion in the hot-swappable first contact (see below). One pin for the benefit of delayed (downtrodden) Startup (staggered spinup) from the power supply so do not start all disks simultaneously and suddenly require a large power demand. Many first-generation SATA hard drives often also have a classic four-pin molex power connector. Also, there are (splitsende) gradient cables are available with an ATA power connector which can be connected to the plugs Molex-. These Molex connectors and adapter cables therefore offer no delayed start or 3.3V connector. For this reason, make a lot of (older) ATA drives do not use this voltage, but it can be so good that some ATA drives with only not operate an ATA power connector with such adapter cable. An important advantage of SATA is that disks can be exchanged while the power is switched on (hot-swappable). A SATA drive can thus be used instead of a USB stick or USB disk, but with greater bandwidth and greater capacity. The disadvantage here is that the removal from most computer cabinets is quite lengthy drives and replacing it - often there are other components in the road so the computer still has to be switched off. However, it is possible to make the (internal) (S)ATA cables, for example by entering an open slot or recess in the computer case to the outside and to introduce an external drive bay or hard disk cabinet again; supporting the SATA standards in practice cable lengths up 90 100cm (al is 45 to 50 previously recommended; the shorter the better). Such long (internal) ATA cables should be available at any well-stocked computer store. The advantage is that it can be made of a separate power supply for the hard disks. It is hereby or extremely important that the ground of the two enclosures being connected to each other. It should also be noted that the cables, that are intended for internal use, outside the cabinet are susceptible to unwanted electromagnetic influences from the environment.

eSATA

Since 2004 has also developed an external variant for connecting external SATA drives.[1] This requires separate (S)ATA cards are available for an expansion slot that also the data cable connection provides instant on the outside of the computer case. The other differences in relation to the single variant are:

• other connectors (lower, snap connection and physically compatible with the internal connectors)

• round, shielded cable against electromagnetic interference

• the shield connects to the earth of both sides with each other

• cable lengths up to 200cm are supported

• In favor of the external and / or longer data cables (with potentially more losses) the specifications of the signal levels have been expanded:

The output signal voltage (transmit) is increased to 500 to 600 mV, instead of 400 to 600 mV, the incoming signal voltage (receive) is lowered to 240 to 600 mV or from 325 to 600 mV instead of

Sata en Intel Sandy Bridge

In januari 2011 Intel released the socket 1155 platform, This generation is also known as Sandy Bridge. In de Chipsets (H67 en P67) is a mistake, however,, allowing the use of the SATA-300 ports (The chipsets support up 4 SATA-300 ports) after about 3 year cycles may exhibit. It may be that the devices on these ports much less likely to work or even not recognized. The SATA-300 ports on motherboards to recognize the simple to the 4 black terminals, of 2 white are the faster SATA-600 ports, which does work correctly. Because of this error, any data on the discs might be lost. Intel has recognized the mistake and goes to work to correct the errors, recalls using laptops and motherboards from some manufacturers, customers can get their money back or another product. The new motherboards where the problem is corrected, have the designation B3.
