What is the difference between SATA and IDE Harddisk?

Parallel ATA (IDE) to serial ATA. The chief visual difference appears when you connect them to the motherboard. A PATA disk uses a 7 in cable that is less than an inch wide. This size granted a cleaner cable arrangement inside the case.

SATA disks offer a significant difference in performance when moving information, and SATA disks can achieve up to 300MB/sec. Soon it will become 600MB/sec. SATA has features that are not located in the former. SATA has adequate disk speed and the ability to connect to a disk on an already running computer. The advanced host controller interface employed in SATA disks allows features like native command queuing. The hot plug feature of SATA disks also made it practical to enable external SATA disks that utilize USB port, turning the SATA disk into a high capacity portable drive.

SATA and IDE are two types of hard disks. SATA stands for Serial ATA hard disk. IDE hard disk can be known by their other names of PATA or Parallel ATA hard disk. One of the main differences between the two is how they appear when they are not hooked up to a motherboard.

The SATA disk will use seven-pin cables, and they are smaller than an inch. The IDE hard disk will use an 80 pin ribbon, and those pins are 3-4 inches. Another difference between the two is the transfer rate. SATA has a transfer rate of 150MB/sec, while IDE has a transfer rate of 133MB/sec

The most noticeable difference between PATA (IDE) and SATA disk becomes evident when they are connected to the motherboard. A PATA disk utilizes an 80-pin ribbon that is about 3-4 inches wide while the SATA disk employs a seven-pin cable that is less than an inch wide, and this allowed for a clearer cable arrangement inside the case.

The difference that SATA disks present a marked difference in execution when transporting data. Even the earliest version of SATA had a minimum transfer rate of 150MB/ SecA, which is already ahead of the 133MB/sec transfer ratio of the fastest PATA disk. Later versions of SATA disks can even reach up to 300/MB/sec. SATA disks are more rapid than old PATA disks. Interface utilized in SATA disks allocates features like Native Command Queuing. That upgraded disk speed more and the capability to link a disk to an already running computer, and this is called Hotplug or Hotswap.

The IDE hard disk is also known as the Parallel ATA or PATA hard disk, while SATA is known as Serial ATA hard disk. The main difference based on their appearance is observed when they are not connected to the motherboard. A PATA disk employs the use of 80 pin ribbon, which has a width of 3 or 4 inches. SATA disk, in contrast, uses seven-pin cables whose width is less than one inch. SATA disks are different from PATA disks in terms of performance when data is being transferred.

The earliest version of the SATA disk had its maximum transfer rate as 150MB/sec, which is already more than the 133MB/sec transfer rate of the fastest PATA disk. SATA disks have some features which are absent in the PATA disks. SATA disks have features like Native Command Queuing, which has improved the disk speed more and also an ability to connect a disk to a running computer.
