The advantages of an SSD storage device are significant. In recent years, you have, therefore, increasingly seen an SSD used as a storage device.
However, there is still one drawback. SSDs are still very expensive compared to a hard disk. That is why a small SSDs are placed next to a large hard drive storage capacity to still have all the advantages of an SSD. Despite the (even) higher price for an SSD. The advantages of an SSD storage device compared to a hard disk are great. Below is a list of reasons why you should choose an SSD instead of a hard drive.
Advantages of an SSD Storage device
An overview of the reasons why having an SSD is the right choice.
The most significant advantage is that an SSD is a lot faster than a hard disk. A hard disk in a desktop computer can read and write 100 to 160MB / s via the SATA 600 standard. An SSD connected via the same SATA 600 cable achieves 500MB / s to 550MB / s.
Do you have an older computer with a SATA 300 connection? Then an SSD will also be an improvement. An SSD will then achieve around 260MB / s. New generations of SSDs are no longer connected via SATA but via the PCI express connection. Such SSDs with a PCI-E connection can achieve even higher speeds of 1000MB / s and more.
Because there are no moving parts, you can always access your data directly. This makes the access time of an SSD much faster. With a hard disk, this is 16ms (milliseconds) that you have to wait before your data is there. This does not sound long, but with an SSD, this is less than 0.1ms!
More energy efficient
An SSD also uses less energy than a hard disk. A hard disk in the desktop of the 3.5 ″ formats consumes around 5 to 9 watts. The smaller 2.5 ″ sizes that you mainly find in portable computers use 3 watts. This consumption is always there, even if the hard disk does nothing, also known as idle. Think of it as the standby mode of television.
With an SSD, the consumption is only 0.1 watt if it is idle. When reading and writing, the consumption is 3 to 4 watts. Keep in mind that most of the time, a storage device does nothing. Do you understand that this is a considerable energy saving? This is a great advantage, especially in portable computers.
Lighter in weight
An SSD is made of a different material than a hard disk. A hard disk is always provided with an airtight metal housing that is relatively heavy. An SSD does not need protection and sometimes only has a plastic housing around the circuit board. In addition, the size of an SSD is always smaller than 2.5 ″.
Less sensitive to shock
Because there are no rotating parts in an SSD, there are also other additional advantages. For example, an SSD is less shock sensitive. Because there is no mechanical arm over a rotating disc. An SSD is therefore also ideal for portable computers because they are moved more than a desktop computer on the desk.
Because there is no rotating magnetic disk and other moving parts, there is an SSD. An SSD is silent. You really hear nothing at all. There is also no fan on an SSD.
Because there is no friction between rotating parts, an SSD produces less heat. This is also an advantage for other parts of the computer. Lower temperatures increase the life of the computer.
Disadvantages of an SSD
However, there are also disadvantages, so that not everyone has an SSD yet.
What is SSD? >>
Higher price per GB
The main reason is the price you have to pay for an SSD. You pay a lot more per GB of storage capacity. Are you looking at new models with a PCI Express connection that is even faster? Then the prices rise even further.
In short, you want a lot of storage capacity of 1000GB or more. Then a hard drive is a logical choice because of the price of around € 85.
That is why you often see the choice of 2 storage devices on a computer. An SSD with low storage capacity can easily be used as a boot disk containing the operating system and the most important programs. And a hard disk with a lot of storage capacity containing all other files such as photos, videos and documents.
This way, you have an ideal distribution of a lot of storage capacity with a relatively low price. But with the advantages of a fast SSD.
Degradation: shorter lifespan?
Another reason that is often mentioned as a drawback is the lifespan of an SSD. This would be shorter than a hard disk.
The lifespan of SSDs is expressed in the number of write cycles on which a memory cell can change to a different value. A chip cannot, therefore, be described indefinitely and suffers from degradation. Samsung, one of the largest SSD manufacturers, is guaranteed to have a lifespan of 1000 cycles.
With a hard drive, these writing cycles are endless, and therefore the life expectancy seems higher. But due to the rotating parts in a hard disk, other factors are also important for the lifespan.
HDD: expected life 3 to 5 years
20% of all hard drives fail in the first three years. Of the 80% who still work after these three years, another 12% breaks every year. In 5 years, about 50% of the hard drives sold have failed. The expected life of a hard disk is 3 to 5 years.
If you compare this with an SSD, the life expectancy is a lot higher. When you use an SSD with more than 30GB of write data per day. Then it takes you 24 years to get 3000 cycles with an SSD of 160GB. The more capacity the SSD has, the longer it will last.
The website Compuram.de performed an SSD lifespan test. The conclusion was that an SSD is perfectly fine for normal consumer use. The guaranteed lifespan of 1000 cycles was also exceeded by a factor of 3 when the first SSD started to show problems.
SSD: expected life of 75 years
The scenario, which applies to most consumers, is saved with 10GB of data every day. If you translate that into the test results of hardware.info, a lifespan of 75 years for an SSD is realistic. In short, as a consumer, you do not have to worry about the lifespan of an SSD compared to a hard drive.
