Data can be stored on the circular divisions of disks known as tracks that can be divided into various sectors that have the data blocks. These drives use rotating magnetic disks known as platters and a mechanical arm, which writes and reads data using the magnetization process. Let us discuss them briefly: Magnetic Hard Drives

Three kinds of HDD technology exist magnetic drives, solid-state drives (SSD), and hybrid drives. Now, let us go ahead and check out the types of technology used in the hard drives: Types of HDD Technology There is an additional wire used that makes it highly compatible with various other devices.Īlso Read: How to Check SSD Speed in Windows 10 It has got general compatibility like a flash drive. They’re quite common in laptops these days. They use flash memory chips rather than storing data and offer faster data access. It makes them very less susceptible to any damage. Solid-state drives are the latest kinds of drives that don’t consist of any moving parts. Small Computer System Interface drives can easily be connected internally & externally. SCSI allows the connection of the different peripheral devices like printers, hard drives, CD-Drives, scanners, and more. They can transfer data much faster (over 150 of 600 megabytes) as opposed to the PATA (133 megabytes), which uses very little power (250mV than 5V) and the cables of SATA are more flexible and thinner. SATA hard disks have now replaced PATA because of its improved performance. This system of PATA drives can be base on science for modern drives.

The earliest drives used PATA that refers to the kind of interface used for connecting your computer with the hard drive.Īround 40 or 80, ribbon cables were used to transfer data in 16bit pockets in parallel.

There’re four different types of drives invented, and they’re the Serial ATA, PATA, SCSI, and SSD.
