Examples of computer hard drives

Hard drives are one of the main components of a desktop computer. Its physical and technical characteristics have to do with the space available on the PC, the speed of data transfer, as well as the amount of storage space that this requires.

Here are some examples of computer hard drives

Enterprise Class hard drives

It is an example of a type of hard disk that is designed for 24 × 7 I / O operation , being able to reach 100% data use in one go, not to mention that they are very reliable. Despite this, these hard drives are extremely expensive and also require a high level of data integrity. The least possibility of corruption of the information they store wll cause great data losses.

Desktop hard drives

It is the most common type of hard drive and it works optimally for 8 hours a day. They are also the most economical hard drives compared to the enterprise class and allow data access and modification fast enough to prevent the massive loss of information in the event of a problem.

PATA hard drives

Parallel Connection Advanced Technology (PATA) hard drives is an example of hardware that is also known as IDE Integrated Drive Electronics Interface and EIDE Enhanced Integrated Drive Electronics drives. The labels relate to the type of interface used to connect the hard drive to the motherboard or CPU board. These hard drives use a 40- or 80-wire cable with a 40-pin wide connector. 40-wire cables are also used on older and slower hard drives, while 80-wire cables are used on faster cables.

Serial ATA (SATA)

In this case, it is an example of a hard drive that uses a completely different connection than PATA hard drives . Although they use a different power adapter than IDEs, these adapters are easily accessible. The main difference between SATA hard disk and PARA hard disk, is that the former is thinner and has a faster data interface compared to PATA disks. SATA hard drives are more efficient and consume less power, which is why they are preferred by many consumers.

SCSI hard drives

These are hard drives that are similar to IDE hard drives. They also spin at a higher rate compared to IDE and SATA hard drives that usually do 7,200 rpm, while SCSI drives can spin at 10,000 or up to 15,000 rpm. The higher the number of revolutions per minute, the faster the access to the information stored on the discs. This feature can also lead to a much faster breakdown. In this case, they are hard drives that require a controller to operate the interface between the units and the motherboard or CPU board.
