Did you know that the ability of a computer to store data is what makes it stand out from other small computing machines like the calculator? To which end the computer has been equipped with two storage options the long term and temporary storage also known as RAM and the secondary storage which can either be internal or external. For the latter, we have the hard drives, flashcards, and media cards, SSD’s, CDs, and DVDs among others.

Computers are designed to carry out varied functions and as regards your needs; you might need a computer with a high processing speed, or larger storage space. Important to note, however, is that there is the primary storage in a computer that has been directly connected to the system’s central processing unit which helps enhance its functionality.

The three kinds of primary storage are the main memory, the cache memory, and the processor registers. Cache memory stores data used by different processing units that help increase the performance of the system. Therefore, all the information available in the main memory is normally duplicated in the cache memory, which tends to have a larger capacity than the processor registers.

The provided computer’s primary storage at times is barely enough, the reason why many external storage devices are a low-cost option when compared to opening up your machine to install a larger capacity device. However, if you have a computer that you wish to discard, you can take its internal hard disk and install it as an additional drive to your new computer.

Types of external computer storage devices

Hard Drives

The hard drive is what stores, your digital content such as programs, documents, application references, pictures, music, and videos, these units are versatile and can either be external or internal. The significance of a hard drive is the amount of information that it can store, which you can also refer to as the storage capacity. This type of storage is however not good for long term use as it will only give you 10 years when you can get up to 50 years with the magnetic tape.

So the primary function of the hard drive in your computer is to provide enough storage capacity and offer faster speeds, it, therefore, maintains all the information on your computer when you switch it off. Hard drives are normally available in two sizes there is the 3.5 inch that is used on the desktop computers and the 2.5 inches adopted for use in laptops. And when it comes to the mechanism, desktop hard drives provide up to 500 Gigabytes, while the notebook hard drives provide up to 160GB.

SSD (Solid State-Drive)

This type of storage device is not very different from the hard drive and works by supporting reading and writing, its best feature is the ability to maintain stored data permanently, even when there is no power. We, therefore, have the internal SSD’s that connect to a computer just like the hard drive.

SSD’s do offer faster speeds, and this seems to be the only advantage that they have over the HDDs because for one they are super expensive and the recovery of lost data on this unit is next to impossible. HDD, on the other hand, tends to be a lot cheaper and offers greater storage capacity.

The one reason that people gravitate towards the SSD is because they help ensure that your computer is blazing fast however, they do compromise on capacity, which then means that you will have to invest a lot of money in your SSD.

When it comes to longevity the SSD does have a longer lifespan when compared to HDD, the reason being the latter are mechanical devices. And when it comes to usability, we can say that SSD’s tend to load information faster than HDD, take for example gaming, if you install all your games on SSD they will load faster as compared to those installed on HDD.

Pen drives

Pen drives are portable memory sticks that are used to store information from a computer and come in varied storage capacities beginning from 64mb up to 32 GB. These units are reusable and rewriteable and are characteristic of a small printed circuit board. Many people can barely tell the difference between a pen drive and USB.

A simple explanation is that pen drives are used to store data while a USB drive, is a media storage device that has incorporated flash memory complete with an integrated USB interface, they are also removable and re-writeable. A USB device is a plug and play storage device, whereas the pen drive is characteristic of a small printed circuit board that provides a sturdy base and acts as a means to collect information.

The above storage devices also work as data recovery options when your computer crashes or when the computer’s primary storage is corrupted. Many people, therefore, store their important information in a separate storage media from their PC’s or Laptops and retrieve them later when needed. Better yet when your primary memory can no longer accommodate the information generated it becomes much easier to transfer and store on an external storage device like a hard disk.

Data loss and recovery

Have you ever deleted information from your computer accidentally, and went bonkers on how to retrieve it; besides everyday PC users run the risk of having their files corrupted through viruses. The idea here is that there are varied activities and things that are a threat to your data and you, which, therefore, need a mechanism with which you will recover your data.

Another service under the free option is the hard drive partition recovery and the raw recovery. So, for more advanced services you have the premium plans that go for $49.00, and at that price, you will be able to recover an unlimited number of files, and this includes the ones that have been formatted, deleted, or lost.

Both the hard drive partition recovery and the raw recovery are accessible in this premium package. Other services that you might need and which are not available in the free plan are the free updates, and the provided free tech support. Lastly, we have the Technician package that goes for $299.00, where you will be able to recover an unlimited number of files.

You will also be able to recover lost, formatted, or deleted data, from any external device or hard drive. All the features that are present in the two plans discussed above are available in the technical in addition to business usage that will allow you to use it with an unlimited number of users, meaning that the service can be extended to your clients.

Data Storage Guide, is an expert data recovery software, and as much it can erase information the vice versa is also very much possible. So for individuals who have sensitive information that they need to erase without leaving any trails, then data storage guide is a safe and reliable way to adopt.

When it comes to the IT infrastructure then there is so much that one needs to be keen on, for example, the storage and the speed of information provision are what many people look at. External storage devices are a perfect back up plan if you don’t have enough space on your Mac or PC system, to which end they come in large varieties as we have the SSD, the hard disks the Pen and USB drive.

Data recovery is the option that you remain with when you lose all your information either through deletion, formatting, or the viruses that corrupt many systems. Do Your Data is, therefore, an all in one solution as concerns your IT infrastructure.
