1TB Internal Hard Disk for Laptop

Internal hard disks are primary storage of a computer or laptop that are inevitable for storing important and confidential data. Though there is new technology emerging standard such as cloud in the market, the exigency for internal hard disk has never dropped. The data transfer speed and inexhaustible storage for the OS are essential in laptops for various applications used by us.

A hard disk in technical terms is a metal platter with a magnetic coating layer that stores data. It stores non-volatile data i.e., data that are not lost after removing the power. It is stored forever unless explicitly it is erased. It has two ports for data transfer to the motherboard and other for powering the disk. The data port uses Serial Advanced Technology Attachment (SATA) or Advanced Technology Attachment (ATA). ATA is a getting older as it has become slow with the parallel port with many pin connectors and cables. SATA is the new trend with few wires and much faster rate than ATA.

The storage in devices may vary from person to person since applications and choices are different. For example, if you are a gamer, you may need high storage with the graphics card for better experiences. Similarly, the need will rise for every individual as now all have the craze for technology and we need much software for our work.

Types of Hard Disk

A hard disk is divided into two types based on the working method.

HDD (Hard Disk Drives) is one type which works with one or two rotating discs in a magnetic field similar to a gramophone.

SDD (Solid State Drives) which has no moving parts but has flash memory.

An internal hard disk for a laptop is 2.5 inches in form factor ( Form Factor is size of the hard drive and how it connects to your computer ) and 3.5 inches/2.5 inches both are compatible for PCs.

Based upon the evolution hard drives are classified into 4 types

Parallel Advanced Technology Attachment (PATA):

It is also referred as IDE (Integrated Drive Electronics). These were the first hard disk which used parallel ATA interface. Data transfer rate at the speed of 133 MBps with a maximum of two devices connected into the drive channel. Since parallel data transferring is involved it uses multiple wires to transfer data.

Serial ATA:

SATA drives are the successor of PATA. Though physical features remain the same, the speed of data transfer is higher in SATA( up to 6 Gbps). The cables used for SATA are thinner and flexible. They require very less power 250 mV.


Small Computer System Interface (SCSI) is similar to IDE. They are faster in operation and are reliable for processing large data. The interface used is a small computer system which is disconnected after the usage. Array handling can be done with better scalability.


Solid State Drives are the latest in computer drive technology. There is no moving part hence the absence of magnetism for storing data. Faster data access is achieved by the semiconductor devices or integrated circuits in the drive. They consume less power and are highly durable.

1TB Hard Disk Buyer’s Guide

While buying an internal hard disk few things are needed to be kept in mind. The factors for buying the disk is given below:

Fast Operation:

Different hard drives spin at different rates. The faster the speed of the system, the faster should be the spin. The higher spin modules cost more at 7,200 rpm with the top capacity of 4 TB which costs more. In order to cut down the high expense, a hard disk is chosen with an average spin of 5,400 rpm in a 1 TB hard disk. HDD has a motor for spinning the disk which defines the rpm. SDD doesn’t have spinning architecture.


The process by which the system drive communicates with the hardware has a major impact on its performance scale. Consumer disks mostly consist of Serial ATA (SATA) with a 3GBps or 6GBps.


Most of the system hard disks are of 3.5-inch form factor which fits easily in the bay areas. Laptops have 2.5 inches 9.5mm sized disks. Newer technologies bring thin hard disks of the size of 2.5-inch form factor which gives sleek look. However, the physical look doesn’t alter the performance. Before buying make sure the size slot fits in sleek drives.


In HDD cache is used for processing the current data. The higher the size of the cache, higher is the speed of multiple data processing.


The budget for a 1TB hard disk may vary from 3K-5K INR based on the brand, applications etc. If you are a gamer, you can pick the drive with the highest configuration which usually costs more.

Heating issue:

Most of the drives usually heat up after hours of work. The heat is to be regulated and the temperature handling of the disk should be good in order to save it from burning due to high temperature.


RAID configuration supports more than one hard drive for smooth operation. RAID (Redundant Array of Independent Disks) supports multiple smaller units of disks to perform independently without overlapping as a single bigger hard disk.
