Hard Drive is an important part of your computer. To buy an External Hard Drive is not an easy task from so much of options available today. So we are discussing below here about the basic & important features that should consider before buying it.
Definition – “A Hard Disk Drive is a hardware device that stores all digital content like – Pictures, Movies, Videos, Files,& Programs, etc. A Hard Drive can be internal or external.”
A Hard Disk Drive capacity is expressed in terms of Megabytes (MB), Gigabytes (GB) and Terabytes (TB).
Cost of a Hard Disk Drive is directly related to its capacity. that means higher the capacity and more costly the drive.

Type of Hard Drive
|HARD DISK DRIVE (HDD)||SOLID STATE DRIVE (SSD)|
|Consist of moving parts & store data using magnetism technology.||Do not consist of moving parts & do not store data using magnetism, instead use of flash memory technology.|
|Lesser durability||Higher durability|
|Higher power consumption||Lower power consumption|
|High access time & latency||Low access time & latency|
|More vulnerable to shock||Less vulnerable to shock|
|Slower data access||Faster data access|
|Higher noise of operation||Lower noise of operation|
|Less expensive per gigabytes||More expensive per gigabytes|
|Best for long term data storage||Best to run an operating system & need frequent access to files or programs|
|Bigger in Size||Smaller in Size|
Key Parameters of hard disk drive
Generally, we all relate the hard drives for its capacity only like 1 TB or 2 TB. But there are more important features like speed, durability, interface, portability, size, cache memory, etc which every buyer should know.
So that a user could do best buying decision of hard drive as per their need. Let’s dive into the world of important features of hard drive and try to find out ours that we need most.
This is the most important feature before buying any hard drive. it is generally expressed in TBs (Terabytes)nowadays. this basically depends upon your need.
For a normal user, 512 GB to 2 GB HDDs storage is sufficient to store all the digital content. Hard drives are available in the market from ranging 1 TB to 16 GB generally.
it is expressed in terms of RPM (revolutions per minute). higher RPM means faster data transfer from and to the drive.
7200 RPM HDD is good, but 10,000 RPM HDD is better.
Buffer or Cache
Buffer or Cache generally, Buffer means memory in computer language. it defines memory storage on the drive in need to transfer data from one section to another.
larger the buffer means faster data transfer. most HDDs have buffer ranging from 8 MB to 256 MB.
In addition to that, a large buffer or cache leads to higher cost.
if your data is too much sensitive, then encryption of data is a must. there are many drives compatible with software encryption solutions.
But if a user required more safety than there are also drives available with hardware encryption having a physical security system like pin code.
Durable & Portable
a solid-state drives are considered more durable compared to hard disk drives due to its small structure and design. as SSD has no moving parts which make them more durable. Hence having good portability also.
Although HDDs are also available in small size from some companies but are too much costlier.
But Some models in HDDs also consider being more durable nowadays.
MTBF and MTTR
MTBF is a technical term and refers to mean time between failure. it is the measurement of reliability of a device. all devices are having large MTBF nowadays.
MTTR refers to the mean time to repair and defines the average time to repair the drives. generally, it has a low impact on your buying decision of a hard drives.
it is rated in gravities (G) for a hard disk drives to measure the level of shock. All modern Hard drives are resistant enough to damage if dropped lightly. it is also not a must feature to consider in buying. But we have mentioned it for your information.
Now we know all the important features and parameters of a hard disk drives. Hence it is quite easier for anyone to make the right choice of the hard disk drives as per the budget. hope you enjoy the article and feel free to connect with us for any query of the above information.
