What is Pata (integrated drive electronics)?
This PATA is also known as ATA or IDE (Integrated Drive Electronics). On each drive, PATA or IDE has its own controllers. So the drive can connect directly to the motherboard. They were the most common interfaces found in the hard drives of most of the IBM computers in early days. As I said PATA was used in most of the hard drives at early times.
What is PATA (Parallel ATA)?
Parallel ATA ( PATA ), originally AT Attachment, is an interface standard for the connection of storage devices such as hard disk drives, floppy disk drives, and optical disc drives in computers. The standard is maintained by the X3/ INCITS committee. It uses the underlying AT Attachment ( ATA) and AT Attachment Packet Interface ( ATAPI) standards.
What does Pata stand for?
From Wikipedia, the free encyclopedia Parallel ATA (PATA), originally AT Attachment, also known as ATA or IDE is standard interface for IBM computers. It was first developed by Western Digital and Compaq in 1986 for compatible hard drives and CD or DVD drives.

What is the difference between IDE and PATA?
IDE and PATA are two terms that people typically get confused over since they are used in referring to pretty much the same hard drives. Although it might seem like there should be some difference between the hardware identified by the two, when it comes to hard drives, there is actually no difference.
Is PATA and SATA the same?
The term SATA is an acronym for Serial Advanced Technology Attachment. PATA is an older technology. SATA is a newer and more advanced form of technology. PATA is basically a connector of 40-pin type.
Is SATA or PATA better?
Increased data transfer rate PATA is capable of data transfers speeds of 66/100/133 MBs/second, whereas SATA is capable of 150/300/600 MBs/second. The speed differences are due to the various flavors of PATA and SATA, with the fastest speeds being the latest version of each currently available.
What does PATA mean power supply?
PATA, short for Parallel ATA, is an IDE standard for connecting storage devices like hard drives and optical drives to the motherboard. PATA generally refers to the types of cables and connections that follow this standard. It's important to note that the term Parallel ATA used to simply be called ATA.
Is PATA still used?
In more recent computers, the Parallel ATA interface is rarely used even if present, as four or more Serial ATA connectors are usually provided on the motherboard and SATA devices of all types are common.
What is PATA used for?
Parallel ATA (Parallel Advanced Technology Attachment or PATA) is a standard for connecting hard drives into computer systems. As its name implies, PATA is based on parallel signaling technology, unlike serial ATA (SATA) devices that use serial signaling technology.
What is the advantage of PATA?
Advantages. The advantage of PATA is that the PATA cables have two devices attached to the cable at one time. One is referred to as device 0 (master) and the other device 1 (slave). A common misconception about using two devices on one cable is that they can only run as fast as the slowest device.
How do I connect my PATA hard drive to my laptop?
Fo example, if you had an old IDE/PATA disk drive, you would connect the IDE/PATA adapter port to the drive, then the Molex plug to the mains adapter. After connecting the adapter to the PC via USB, switch it on. The drive would be detected as a USB device by the operating system, ready for you to browse.

How many gigabytes is an ATA drive?
The first drive interface used 22-bit addressing mode which resulted in a maximum drive capacity of two gigabytes. Later, the first formalized ATA specification used a 28-bit addressing mode through LBA28, allowing for the addressing of 2 28 ( 268 435 456) sectors (blocks) of 512 bytes each, resulting in a maximum capacity of 128 GiB (137 GB ).
How long is a parallel ATA cable?
Parallel ATA cables have a maximum allowable length of 18 in (457 mm). Because of this limit, the technology normally appears as an internal computer storage interface.
How fast is ATA 4?
The ATA/ATAPI-4 standard also introduced several "Ultra DMA" transfer modes. These initially supported speeds from 16 MByte/s to 33 MByte/second. In later versions, faster Ultra DMA modes were added, requiring new 80-wire cables to reduce crosstalk. The latest versions of Parallel ATA support up to 133 MByte/s.
When did ATA come out?
Soon after the introduction of Serial ATA (SATA) in 2003, use of Parallel ATA declined. The first motherboards with built-in SATA interfaces usually had only a single PATA connector (for up to two PATA devices), along with multiple SATA connectors. Some PCs and laptops of the era have a SATA hard disk and an optical drive connected to PATA.
When did ATA over Ethernet come out?
In August 2004, Sam Hopkins and Brantley Coile of Coraid specified a lightweight ATA over Ethernet protocol to carry ATA commands over Ethernet instead of directly connecting them to a PATA host adapter. This permitted the established block protocol to be reused in storage area network (SAN) applications.
Why is the AT bus called an ATA?
The standard was originally conceived as “AT Bus Attachment”, officially called AT Attachment and abbreviated as “ATA” because its main feature was a direct connection to the 16-bit ISA bus introduced by IBM. When the SATA interface was introduced in 2003, the original ATA was renamed Parallel ATA or PATA for short.
Can you connect two SATA drives in parallel?
The current SATA interface works in series, so it is not possible to connect more than one device with the same data cable, but the IDE interface, being in parallel, did allow it. However, when two devices were connected with the same cable, one should be designated as device 0 (Master) and the other as device 1 (slave). This distinction was necessary to allow both drives to share the same data cable without conflict, and it was made with the famous jumper incorporated in hard drives and optical drives of the time.
What is PATA/ATA/IDE?
PATA is the short form of ‘Parallel Advanced Technology Attachment’ which is actually an interface for connecting the processor and the drives. It should be clear, by interface I mean the way in which your computer and the hard drive is connected. This PATA is also known as ATA or IDE (Integrated Drive Electronics). On each drive, PATA or IDE has its own controllers. So the drive can connect directly to the motherboard. They were the most common interfaces found in the hard drives of most of the IBM computers in early days.
Why is SATa cable shorter than PATA cable?
So if you use SATA connection, being short in size the cables allow increased airflow inside of the computer case as well as a decrease of heat buildup. This ultimately increases the longevity of computer life.
How many SATa drives are there on a motherboard?
Usually, there are four to six SATA connections in a normal motherboard which allow multiple SATA hard drives to hook up. On the other hand, there are only two PATA connections in a motherboard, allowing a total of four PATA hard drives to be connected.
What is a serial ATA?
Like I said earlier, Serial ATA or SATA and Parallel ATA or PATA are two interfaces that are basically used for connecting to storage devices like hard drives and optical drives. And as it occurs, SATA is the successor to PATA, more likely, PATA is now mostly outdated.
How much power does a SATa drive use?
The SATA drives usually need very little power than PATA drives. The SATA drive usually uses only 250 mV of power, which is even 25 percent of one volt. If you look at the PATA drives, you will see that they require a 5V power connection.
How wide is a SATa cable?
When you have extra length in cables, more flexibility of the positions of the drive can be attained. Moreover, the SATA cable has two 0.25-inch-wide cables which are far narrower than PATA cables. So the SATA cables take up less space in the computer case than the PATA cables. It saves space in there.
What is a SATa?
SATA means ‘Serial Advanced Technology Attachment’ . The main characteristic which differentiates SATA from PATA is that in SATA the information moves between the hard drive and motherboard as serial one, i. e. one bit after another. The main motivation behind the creation of SATA was the increase in the drive speed.

Parallel ATA cables transfer data 16 bits at a time. The traditional cable uses 40-pin female connectors attached to a 40- or 80-conductor ribbon cable. Each cable has two or three connectors, one of which plugs into a host adapter interfacing with the rest of the computer system. The remaining connector(s) plug into storage devices, most commonly hard disk drives or optical drives. E…

Compact Flash in its IDE mode is essentially a miniaturized ATA interface, intended for use on devices that use flash memory storage. No interfacing chips or circuitry are required, other than to directly adapt the smaller CF socket onto the larger ATA connector. (Although most CF cards only support IDE mode up to PIO4, making them much slower in IDE mode than their CF capable speed )

The following table shows the names of the versions of the ATA standards and the transfer modes and rates supported by each. Note that the transfer rate for each mode (for example, 66.7 MB/s for UDMA4, commonly called "Ultra-DMA 66", defined by ATA-5) gives its maximum theoretical transfer rate on the cable. This is simply two bytes multiplied by the effective clock rate, and presumes that every clock cycle is used to transfer end-user data. In practice, of cours…
