Hard Drive:
The main storage device of a computer where all data is saved. Hard drives are non-volatile which allows the data to be saved even when the computer is shut down. “Although most hard drives are internal hard drives, many users also use external hard drives to backup data on their computer and expand the total amount of space available to them”( "What Is Hard Drive?" Computer Hope. Web. 14 Sept. 2014.) The first Hard Drive was released by IBM in 1956.

Random Access Memory (RAM): Another form of computer storage, RAM is what allows data to be accessed and read from random parts of a computer. RAM is volatile memory which means it can lose data being stored in it when the power is shut off. ”RAM is the most common type of memory found in computers and other devices, such as printers” (Beal, V. (n.d.). RAM - random access memory. Retrieved September 14, 2014.). When you start getting low on RAM the operating system then dumps some of the open programs from the RAM to the hard drive which can increase load times.

Solid State Drive (SSD): Solid state drives are actually quite a bit different than hard drives in that they are able to transfer data faster and also don’t have moving parts that can break down. They are also non-volatile memory units. The first Solid state drive was implemented in IBM supercomputers in the 1970s and 1980s. Unlike Hard drives and how they save using magnetism, Solid state drives save with interconnected memory chips that save even when no power is available (Domingo, Joel. "SSD vs. HDD: What 's the Difference?" PCMAG. Web. 14 Sept. 2014.).
Cloud Storage: Cloud Storage is data that is stored in logical pools, where the physical storage is across multiple servers at certain locations. Many companies like Google and Amazon use cloud storage as they only pay for storage they use, can be used as a backup after natural disasters due to multiple backup servers being around the globe, and the

    A solid-state drive is a drive that uses non-volatile memory as a means of storing and accessing data, similar to computer RAM (SSD, 2014). An advantage the solid-state drive has over other hard drives is no moving parts. This allows the solid-state drive to access information faster, produces no sound, and significantly more reliable than the common hard drive. The first solid-state drive was designed and implemented between the 1970s and 1980s. Throughout the years, the storage capabilities have improved drastically. Sadly, due to the cost per GB of storage, these solid-state drives have not replaced the current hard drive in computers today.…

    Solid State Drives is the new technology behind storage capacity be it in computers, PCs, and pretty much anything that utilizes 0’s and 1’s, nowadays. Compared to HDD (Hard Disk Drives), they surpass this old age technology at every aspect, from performance to life expectancy. However, SSDs are more expensive too in that respect, but considering all the advantages, the hefty price tag is a small price to pay, especially if you have data that is so crucial that you can’t bring yourself to part with it. Speaking of back up storages, and forgetting everything that you know right now in terms of design and architecture between the two, which option is safer to use as compared to the other?…

    Hard drives have been around longer than you think. In 1956, I. B. M. had invented a disk storage unit that was very large but did not store a lot of data. It was twenty-four inches in diameter and could hold only five megabytes, which is the equivalent to three and one half floppy disks. Originally called “fixed disks” later became known as “hard disks” opposed to floppy disks. In 1973, I. B. M. released a hard drive that could hold seventeen and one half megabytes. In 1980 Seagate made the first five and one quarter inch hard disk. In the late 1980’s, three and one half inch hard disks were invented (PCIN). Although there are smaller hard disks as small as two inches in diameter, three and one half inch hard disks have been made a standard and is used most often today. The capacity in hard drives has excelled thousands of times all over from five megabytes to one hundred sixty gigabytes (160,000 megabytes) which is the equivalent to one hundred eleven thousand one hundred eleven floppy disks. The hard drive or hard disk is one of the most critical components in the operation of a computer. It is also one of the only moving parts in the computer. Sadly, many people do not know the important role it has in the storage of their data or how it even works.…

    Solid State Drives (SSD, solid state disk) storage industry is currently much attention storage of new technologies, it is seen as a revolutionary storage technology, it might give the storage industry and even computer architectures bring profound changes. it is an electronic device rather than physical mechanical devices, it has a small, low energy consumption, anti-interference ability, addressing time minimal (or even negligible), IOPS high, I / O high performance characteristics. Therefore, SSD memory and external memory can effectively shorten the gap between the storage, the computer system had to solve the I / O performance bottleneck of many components and the role of technology will become increasingly insignificant, and even eventually be eliminated.…

    All computers have hard drives in order to store information on its system. The hard drive allows the computer to remember or store information even while it is turned off. All computers need at least one hard drive to store all operating systems, user information, and programs. The hard drive is the largest storage device on the computer (measuring the size of a paperback book). Some computers have more than one hard drives which the computer will label them as being “C”, “D”,“E”, and so on. You can also choose to use an external hard drive for mobility purposes without having to carry a whole desktop computer around. Most users have external hard drives for extra storage space. Some users also store their most sensitive and confidential information on them and store them in secure places.…
