The Secret Behind Solid State External Hard Drives

Computers have a really large book of history with it. The first computer had black and white screens and does not have any other programs aside from that which could be compared to a command prompt we see in modern computers. There is no specific person that invented the computer. It is actually a work in progress until this very moment. Computers had certain developments in each phase, this way the ability of computers to do tasks keeps on increasing over time. From simple computing tools to incredible machines, computers made its way in creating the digital age. Thanks a lot to all the people who contributed to the development of computers or else we would not have many of what we see today.

The first developments were focused in its functions, and its capability to process data. And these computers were not sold commercially; they are created for specific purposes like science experiments and space projects. The first programmable computer and the first to be sold was made back in 1936 by Konrad Zuse and released in 1941. This computer is called the “Turing Complete Z3”. The Z3 is a large machine that could cover a whole bedroom. From this point on the development of computers became unstoppable.

Modern developments

In modern computers the developments in functionality still increases but so does other components. In today’s computer the developments are focused on the output power of each computer, including its size and capability. Computers can do so much more functions compared to its ancestors. Today’s computers can now be used for networking, games, communication and many more. The improvements are focused on the graphics, the sound quality, the speed, hardware durability and memory. Everyday computers are being made in order to rival the earlier models.

Virtual Memory

One of the unending components that have been developed is the computer’s virtual memory. This is the ability of computers to store a given amount of data. This memory is measured in “bits”. The bits grew larger and larger in order to accommodate more data. As of today, the largest memory that could be integrated in a computer is measured in “terabytes” or TB.

Before the only data that could be stored in virtual memory are numbers and texts, but due to modern technology any types of information like audio, images and other materials can be stored in a virtual memory. This is made possible by transforming these types of data into what we call “bits” and stored in the drive.

In modern technology, “Random Access Memory” or RAM is the primary memory device of computers. They are low in capacity nut they move so much faster. Secondary memory devices have a lot of capacity but they need primary memory devices such as RAM to move faster. The secondary memory is where the real data is stored. The primary memory helps the fast access.

This is where the famous “Hard Disk Drives” comes in. This is a device that stores and edits data using a rotating disk inside. The disk records the data, and using certain instructions these data could be edited.

The first hard disk drives or HDD were large. One block of this could be compared to a large household oven with stoves; and this could only contain limited amount of data. So just imagine how much laboratories would use just to accommodate large amounts of data. Modern hard disk drives could contain large amount of data in limited space. These types have small, but high capacity disks inside that rotate, compared to large, small capacity, metal disks that they use before.

Hard Disk Development – Solid State External Hard Drive

Since this is the time in the planet when we improve the technologies of the past, it is not enough to remain using Hard Disk Drives. Due to inventive and created minds the “Solid State External Hard Drives” were created. So what? They both save data, right? Yes they do both save data but the manner in which they do so is different. Hard Disk Drives have metal platters that rotate in high speed inside the unit. And these metal plates are covered with magnetic coating where the data is actually stored. This data is being read by a small pin like the ones they use in ancient versions of music players. Since Hard Disk drives operate with a mechanical part, it is more susceptible to wear and tear. The magnetic coating is also in danger of losing its data once a magnetic interference will touch the coating. Hard Disk Drives need power to retain data; this concept is called “volatile data”. Solid State External Hard Drives does not have any mechanical parts so you can eliminate the idea of wear and tear. Solid State External Hard Drives uses flash memory chips integrated in the unit so even if there is no power, the data is still there. Since it is functioning mainly using chips, the power consumption is not that large. This means that if you are using a laptop, the battery life will be longer using Solid State Drives compared to HDD. And the best part of this is that it is “External” that means you can bring it anywhere with you and connect it to any functioning computer you want. This is life really on the go.

You might be thinking what is the difference between Solid State External Hard Drives and Flash Drives? Basically, they do function in the same way; both do not need power to retain data, they don’t have moving parts, they are portable and they could be connected to any computer. The difference lies with the capacity and durability of both components. Solid State External Hard Drives can contain much more data than ordinary flash drives. Aside from that, flash drives have smaller components that break easily once the data is changed several times.

Change is inevitable and so is going with the flow, but if it means moving up to the world and doing the best you can do with technology, what can go wrong?
