In this article, we are going to explain Different Types of Hard disks. Hard Disk is also called a “Hard Disk Drive” This is a non-volatile memory hardware device. Hard disk work is to retrieve and store computer data enduringly. It’s called non-volatile devices, Which can store any kind of data in the computer for a long time, which is the computer keeping the data safe even after power is off. Hard Disk is also called SSD (Secondary Storage Device). It exists inside a computer case (CPU) and is joined to the computer and Best Mining Motherboards using data cables (PATA, SCSI, SATA).
Types of Hard Disk.
There are four types of the hard drives as follows:
- Parallel ATA
- Serial ATA
- Small Computer System Interface
- Solid State Drives
Parallel ATA
Parallel ATA drives are one type of hard drive. They are also IDE (integrated drive electronics) or EIDE (enhanced integrated drive electronics) drives. Using the PATA interface standard, this is the first hard drive connected to a computer. The Parallel ATA drive was invented by “Western Digital” in 1986. This provides a driver with a standard interface, which is generally used on different devices at the time. PATA drives can provide data transfer rates up to(133 MB/s). In the master/slave configuration, 2 PATA drives can be connected with one cable.
Serial ATA (SATA)
As one of the HDD types, Serial ATA (SATA) hard drives are still considered the most common type of hard drives used today. It roughly supports all computer motherboards and operating systems. Serial ATA drives are commonly one of two (3.5-inch) hard drives for desktop computers and (2.7-inch) small hard drives for laptop computers. This disk of drive rotates at different speeds according to the model purchased. The speed can reach “10,000 RPM” to increase data transmission, and storage devices used in big servers can reach “15,000 RPM”. However, grater RPM Serial ATA drives are also more prone to failure. Mechanical failure is one of the fundamental disadvantages of SATA drives.
Small Computer System Interface (SCSI)
A Small Computer System Interface is also one the kinds of the hard disks. SCSI was developed in the “1970s” and was given the first name SASI Shugart Associates System Interface after the company was founded. A 50-pin flat ribbon connector is used to connect hard drives and other peripherals to the computer. Accompanying standard interface technology, seven to fifteen devices are allowed to connect to a single motherboard. Although it is usually believed that SCSI is outdated, the Small Computer System Interface can still be found in some low-end computers. Modern (SCSI) cables can transfer data at up to 80 MB/s
Solid-State Drives (SSD) (Different Types of Hard Disk)
The solid-state drive (SSD) is one of the complex drive types. Today, This is at the forefront of storage technology progress. The SSD is a storage drive composed of memory chips rather than rotating magnetic disks in traditional hard disks. The SSD (solid-state drive) does not have rotating disks or any other moving parts. Instead, in the SSD, the data is stored in the semiconductor chip. SSDs work using the idea of flash memory, that is the same idea used in the RAM (random access memory) of the motherboard. a solid-state drive (SSD) lacks mobile parts, like this, the SSD’s operating power consumption is greatly reduced. This is one of the advantages of SSD. Another advantage of this drive is that, it is not prone to failure. However, the largest disadvantage of SSD is the cost.
