Come, friends, today we will know that Hard Disk Kya Hai.
What are the types of hard disks?
What is Internal Hard Disk and What is External Hard Disk?
What is IDE, SATA, SCSI, SAS?
So friends, we will fall down that Hard Disk Kya Hai.
What are the types of hard disks?

Hard Disk Kya Hai  : -

A hard disk drive is an storage device that we use to store data.  We also call it a hard disk drive.  The first hard disk was created by IBM company.  The hard disk drive consists of a circular disk.  In which digital data is saved.  It rotates very fast which we measure with RPM.  The higher the RPM the hard disk has, the more it reads data at the same speed most hard disks are at 5400 RPM or 7200 RPM, the higher the RPM the hard disk will be.

Type Of Hard Disk Drive  : -

Connects to the computer via an internal hard data cable (IDE, SATA, SCSI, SAS) that connects to the motherboard and is also connected to a power supply with power cables that connect it (20,24, Or  4) is of

Capacity for transferring and storing data of different types of Hard Disk is different, it is as follows  -

IDE ⇒ (Intergrated Drive Electronics)  : - They are also called DE (Drive Electronics) and PATA (Parrallel Advance Technology Attachment Drive) It can send 8 bit data at a time.

SATA ⇒ (Serial Advances Technology's Attachment Drive)  : - Can transfer up to 300MB of data every second. SATA Cable is used to connect SATA Hard Disk, only one drive can be connected.

SCSI ⇒ (Small Computer System Interface Drive)  : - Can transfer up to 640 MB of data every second. SCSI cable is used to connect SCSI Hard Disk, up to 16 drives can be connected simultaneously.

SAS ⇒ (Serial Attached SCSI Drive)  : - In this, 805 MB data can be transferred simultaneously every second, with its cable we can add 128 drives.

Internal hard disk  : -

Internal Hard Disk This hard disk is installed inside the computer, hence this hard disk is called internal hard disk.  This hard disk is mostly used.  We install our software and operating system on these hard disks.  They are connected to the computer via the SATA or IDE interface.

External hard disk  : -

External Hard Disk We can also be seen in our phones and also in our laptops and computers, but talking about external stories, we can increase the storage of our phones by using micro SD card for our phones.  External hard disk is also used for external storage in your computer and you should use hard disk with maximum capacity.
