Types of External Hard Drive

Hard drives or hard disk drives are the part of your computer setup which is used to store the data of your system. When the hard drive of your computer is full and you need more space to store the at that time you require external hard drives to fulfill that requirement. So here in this blog type of external hard drives are describe below.

There are mainly 4 types of external hard drives are available:

1- Enhanced Integrated Drive Electronics: It is one of the external hard drive including parallel advanced technology attachments. But nowadays due to advancement in technology in other drives its popularity become decreases. The fastest and newest EIDE variants use cable of 80 wires while old one works on 40 wire cable. In it hard drive recovery takes some time time because of its slower speed.

2- Serial Advanced Technology Attachments: It is also known as SATA. These are the hard drives with some advanced feature then EIDE describe above. These are less heavy than EIDE. It has a major advantage that it consumes less power comparison to EIDE.

3- Solid State Drives: It is the best hard drive to use for storage the data. It is made up of stationary part that is in it no moving part takes place. It is commonly known as SSD.

4- Small Computer System Interface: It is commonly known as SCSI. It works in same manner as EIDE works but the difference is that it has much faster speed to process and store the data.

Basics of Computer Hardware:

This blog describes you about the hardware component of your computer. In this blog here I describe some important hardware basics which is helpful for you to make a new computer setup.

Basics of computer hardware component:

1- Motherboard: Motherboard of your computer is the main part of your computer system. Motherboard is used to connect all the input/output devices together. These devices are RAM, video cards, sound cards, processor, USB port etc.

2- Hard Drive: Hard disk of your system is a source of storing your data, files,music,videos, pictures etc. If you want to store more space to store the data then external hard disk is also available in market to store the data.

3- RAM: RAM that is Random Access Memory of your computer system is used to store the data.It stores the data on temporary basis. It is volatile memory that is data is lost when power supply is off.

4- Processor: Processor is called the brain of the computer. It used to process all the data of your computer. So, to make your computer working properly use best quality of processor.

5- CD/DVD Drives: If you want to watch a movie with CD or DVD, then it is necessary to install CD or DVD drive in your computer.

Disk de-fragmentation, problems and solutions

Is your computer running very slow?? oops!!nothing to worry about it,  just read this blog and you will find your solution.

computer system is what its a machine and its system like human body system, in long run it too get slow, so some efforts are needed to make it run properly. As we go to gym, do yoga, morning walk just to make us fit and fine, So likewise some efforts are needed to a computer system too. Do'nt got frightened,  just go on, its very effective and will help you a lot.

What Is Fragmentation?

Fragmentation, by definition, means “the state of being fragmented,” or “something is broken into parts that are detached, isolated or incomplete.” Fragmentation is essentially little bits of data or information that are spread over a large disk area causing your hard drive to work harder and slower than it has to just to read a single file, thus affecting overall computerperformance.

Disk defragmentation

As the name sounds it's the opposite of disk fragmentation. Defragmentation is essentially a realignment of data on a hard drive's physical disk to optimize the disk's ability to access data. It  is the process of organizing the data on a hard drive so that data for a given program or file are saved "contiguously," meaning all on the same part of the disk. It also attempts to create larger regions of free space using compaction to impede the return of fragmentation. Below some topics are given to make you understand it better.

Why is disk defragmentation needed?

Disk fragmentation is needed to arrange the free space available on the hard disc, to best optimize it, so that data feeded to it can be properly arranged and can be recalled back easily in few seconds of time. In a nut shell we can say that it increases the performance of the system. In simple terms, file defragmentation is the process of putting file pieces back together.

Free disk defragmentation tool in windows

Disk Defragmenter is accessible through the accessories folder of the Windows Start menu, steps are as follows,

• Click windows start menu.
• Click All programs,then Accessories.
• Go to system tools.
• Click Disk defragmenter.

Problems related with disk defragmentation

Windows already have free utility disk defragmentation tool, but it cannot perform the following functions.

• Incomplete. Can’t get the job done.
• Won’t defrag free space.
• Resource intensive. Can‘t be run when the system is active.
• Servers? It can’t keep up with them.
• Hangs up on big disks. You never know what the progress is.
• Eats up IT admin time administering.
• Takes forever. May never finish.
• Effects of fragmentation still not eliminated!

Effects of inefficient defragmentation

Inefficient defragmentation means

• Higher help desk traffic,
• More energy consumption,
• Shorter hardware life,
• Less time to achieve proactive IT goals, 
• Throughput bottlenecks on key consolidation economies such as virtualization. 

Solutions

In market there comes lots of free disk defragmentation tools, but they cannot perform the function upto the mark. So i will suggest you to go for the paid priemium version of defragmentation tools having a licensce key.
