In today’s age of digital computing, we have become more and more dependent on hard disk drive and all of us probably know what a hard disk drive looks like, but I bet most of us have no clue as to what it does, how it does things and why?
The history of hard disk drive can be traced as far back as 1954 with the first hard disk drive invented by IBM in the United States. Quoting Wikipedia, the very definition of a hard disk drive is a data storage device used for storing and retrieving digital information using rapidly rotating disks (platters) coated with magnetic material. Data is read in a random-access manner, meaning individual blocks of data can be stored or retrieved in any order rather than sequentially. An HDD consists of one or more rigid (“hard”) rapidly rotating disks (platters) with magnetic heads arranged on a moving actuator arm to read and write data to the surfaces.
The power of a hard disk drive is that it is able to store digital information in a relatively permanent form, even when the powers are out. They give computers the ability to remember things and store it safely inside them.
There are three major areas for us to measure the performance of a hard disk drive and to differentiate one hard disk drive to another (the other one would be the price):
The first one is the Data Rate which is the number of bytes per second that the drive can deliver its data to the CPU. Normally we can see rates between the range of 5 to 40 megabytes per second with higher being faster and better.
Next is Seek Time which is the amount of time between when the CPU requests a file and when the first byte of the file is sent to the CPU. This number is normally between 10 and 20 milliseconds with a lower number means better performance.
The final area would be the actual capacity of the hard disk drive which is the number of bytes it can hold. Today we can see it ranges between 1 Terabyte (or 1,000 Gigabyte) up to 8 Terabyte with a higher number means that it can store much more data.
With so much data a hard disk drive can hold and how we have become more and more dependent on it to store all our data; be it our important documents, precious family and vacation photos, our favorite songs and videos, it is becoming increasingly important to have some reliable and effective data recovery services available.
Imagine one fine day our hard disk drive fails to work properly and all our data on it is gone, it would be a massive headache for us to get it back unless we have a good recovery software that can restore it back to its original state, before the disaster happens.
Well now we do have a safe, complete and effective data recovery software called EaseUs Data Recovery Wizard. It can be used to recover lost files either from the Recycle Bin, lost or deleted partition and basically all lost files from your hard disk drive.
There’s the free version or a paid version starting from USD69.95 to cater for all your various needs. It is highly recommended by those in the software industry and is being trusted by millions of users, so you can’t be wrong with it.
