Not until a few years ago could people make a choice about what kind of file storage they want with their new desktop, laptop or ultrabook computer. There are two storage components one can choose to get: HDD or SSD drive. Which one is better? If you are being tormented by this question, you should know that there is no definite answer to it.
It all depends on your personal preferences and budget.
Your system can be configured by either one of these storages or both (in some cases). In this article you will have the difference between HDD and SSD explained, with all their advantages and disadvantages, so to make your hard drive purchase easier.
So, what’s the difference between an SSD and a HDD?
Both SSD and HDD are connected to your PC’s motherboard, enabling your data to be processed. Their job is to store your personal files, applications, and boot your system. However, these two storages have their own unique feature set, and the question that is being imposed quite naturally is: why should you opt for one over the other?
SSD stands for Solid State Drive, and it can be perceived as a more sophisticated and oversized version of a USB flash memory stick. Information in an SSD is stored in microchips, and is read/written by a processor (called the controller). What separates an excellent from a good SSD is a good controller technology. SSD is a type of permanent and non-volatile memory, and the data storage life can be maintained for over 200 years.
HDD (or Hard Disk Drive) technology has been present in the technology world for quite some time now. It stores data on a rotating platter by using magnetism. It uses a mechanical arm with a read/write head that moves around and reads it from a rotating storage platter. The faster it spins, the faster a HDD can perform. Typical HDDs spin at 5400 or 7200 RPM.
When it comes to speed, SSD technology grabs the first place. Computes with an SSD will boot faster (usually under a minute), launch programs and applications faster, and have a faster overall performance. Having extra speed always comes handy, no matter what you use your computer for (school, business, or gaming). When compared to SSD, HDD has longer read/write times, higher latency and fewer input/output operations per second (IOP).
If it happens that you drop your tablet or laptop on the ground, an SSD memory will most probably keep your data safe because it has no moving parts. HDDs have mechanical parts, arms with read/write heads, and malfunctions are more often with them. An SSD is recommended if you are a bit rough on your equipment.
HDD’s drive platters work best with larger files. Due to their rotary recording surfaces, the files are laid down in contiguous blocks. These large files can become scattered around the platter when the drive starts to fill up, and that is known as fragmentation. The very fact that HDDs can become fragmented, while SSDs do not care where the data is stored, makes SSD technology better, faster and more reliable.
HDD drives are heavier than SSDs because they incorporate rotating platters, motor and spindle. Because of that, there is a limit for a HDD drive size. SSD drives do not have that kind of limitation and they continue to shrink. Laptops are becoming slimmer and tablets are becoming primary platforms for Web surfing, so the SSD technology will take over the market because of its size, speed and practicality.
HDD technology has rotating platters, thus uses more electricity. It generates more noise and heat, unlike a typical SSD hard drive, which is non-mechanical so no such rotation is needed. If a system is shoddily mounted in an all-metal case, even the quietest HDD will produce a small amount of noise.
Availability & Price
Internal HDDs are more plentiful and will stay around for the next few years. There are still more HDD choices than SSDs, with SSD model lines growing in number. As for the price, they differ in dollar per GB. For example, you will pay up to $75 for 1TB internal 2.5-inch HDD storage. An SSD with the same form and capacity will cost you double the price, up to $150. HDDs will stay cheaper and be in the majority for internal PC storage device in the period to come, for they are older and more established technologies.
In the end, i.e. an SSD vs HDD, when you consider common and maximum capacity, SSD memories of 4TB storage space are expensive and rare. The most common primary drives are 500GB to 1TB storage units. SSD drives are better when it comes to fragmentation, noise, speed, form and ruggedness, but capacity and price issues are its setbacks. HDDs offer larger storage space, are cheaper and more available.
