Difference between SSD and HDD in Laptops & PCs
Difference between SSD and HDD in Laptops & PCs – Currently, new storage media are widely used as a replacement for HDD (Hard Disk Drive). The storage media is SSD (Solid State Drive) which is faster, better performance and lower power consumption. Where SSDs are commonly used in the latest laptops or notebooks.
Basically, laptop and PC SSDs are the latest generation of storage media to replace the HDD role. SSD itself is a data storage device with a series of ICs as memory for storing data. Like the USB Flash Drive, SSDs don’t use plates to store data, but instead use a microchip.
Unlike the HDD which moves mechanically by using a dish to store data. Of course you need to know how to distinguish SSD and HDD, now for a more complete discussion of the differences between hard drives and SSDs, please refer to the article below.
There are several fundamental differences between SSD and HDD storage media, ranging from price, components to read and write speeds. The following is a discussion of the comparisons and differences of HDD and SSD.
1. Difference between SSD and HDD of Form
The most basic way to distinguish SSD and HDD can be seen in terms of shape and size, where the hard drive has a larger shape. This is because the components in it, such as the R / W head, spindle, platter or disc and so on.
Meanwhile, laptop and PC SSDs no longer use these components, but use flash memory and PCD boards, so SSDs are suitable for laptop or notebook devices because they have a more practical size and are lighter in weight.
For size, currently SSD has a size of 2.5 inches that can be installed on notebooks, laptops and 3.5 inches for desktop PCs. So that the SSD on this laptop can support a thinner device design. Even the M.2 and M.2 NVMe SSDs have a smaller size like RAM.
2. Difference between SSD and HDD from the way they work
The next difference between hard drives and SSDs is part of how it works. The mechanical part of the HDD consists of a head and actuator connected to a dish or platter. The process of reading and writing data is done through a mechanical process in which the disc is rotated by the spindle while the R / W head is connected to an electronic component that processes the data.
While SSDs use electronic components such as integrated circuits (IC), microchips and other supporting electronic components such as capacitors. The entire process of reading and compiling data is processed electrically the same as on flash and RAM.
3. Difference between SSD and HDD from Read / Write Speed
In terms of speed, SSDs show a very significant difference in speed. The read write speed of an SSD can even be many times faster than an HDD. A laptop or PC that uses an SSD can go through a very short boot process, which is in just seconds.
On the other hand, the time needed for the HDD is longer depending on the specifications, but still cannot exceed the boot speed of the SSD. In this case, the SATA HDD has a transfer speed of around 170MB / s, while the SSD has a speed of 500MB / s and more than 3000MB / s for the M.2 MVMe type.
4. Difference between SSD and HDD from Fragmentation
Fragmentation is a term for referring to an empty space on the storage media due to changes and deletions of data. If left unchecked this will cause a decrease in performance on storage media, especially HDD.
On the HDD side, defragment is needed to maintain health so that there is no significant decrease in performance, so that the HDD can be used intensively. If you are still using HDD, you should routinely do defragmentation either using Windows built-in tools or additional applications.
On the other hand, on an SSD device, users do not need to do a defragment like HDD. This is because SSD already uses flash memory technology.
5. Difference between SSD and HDD from Usage Effects
And the difference between SSD and HDD is further seen in the effect of use. When using HDD, the device will heat up more easily because it uses a rotating dish which can also cause noise. HDD also requires higher power.
In contrast to SSDs, when using SSD the heat effect is not that high and more stable. In addition, SSDs also do not require high voltage thanks to the chip technology used.
6. Differences between SSD and HDD in terms of service life
On HDD, age can depend on how it is treated. If users are diligent in carrying out treatments such as fragmentation and avoiding possible physical damage such as collisions, HDDs can have a long service life. HDDs that begin to fail and need to be replaced can usually be seen when they experience bad sectors.
Unlike the case with SSDs whose usage age is calculated based on Terabytes Written (TBW) units. In simple terms TBW is a count for each time the SSD rewrites data. In this calculation, the SSD will experience a decrease in performance and will most likely be damaged when it reaches the TBW limit.
7. Difference between SSD and HDD in terms of price
The difference between the last SSD and HDD is in terms of price. On this side, the price comparison between HDD and SSD is quite significant, where SSD is relatively more expensive than HDD price.
For example, the Samsung brand laptop SSD with a capacity of 120GB has a price of around 350 thousand. Meanwhile, at a price of 350 thousand, you can already get a hard drive with a capacity of 500GB.
The advantages and disadvantages of SSD and HDD
As previously explained, HDD uses a mechanical system, so it has a certain effect as it is used. Here are some of the advantages and disadvantages of HDD.
- The price is relatively cheaper (+)
- More capacity for storing various files (+)
- Has a higher heat effect (-)
- Higher power consumption (-)
- The rotation of the disc and the engine makes a noise (-)
As for SSDs which do not use a mechanical system, of course it has its own advantages. Here are some of the advantages and disadvantages of SSDs.
- Read / Write speed is much higher (+)
- The temperature on the SSD is more awake (+)
- Save more on the use of electric power (+)
- There is no engine and disc rotation, so it does not make a sound (+)
- Price is more expensive than HDD (-)
- Smaller capacity (-)
How to find which SSD is suitable for aptops and PCs
Before buying an SSD to be installed, especially on a laptop, then you need to know the right type of SSD. Here’s how to find out which SSD is suitable for your device.
Choose the size
It has been explained above that the laptop uses a 2.5-inch SSD which is also the standard size for laptop HDD. As for PCs, you can use 3.5-inch and 2.5-inch SSDs. But for 2.5 you need to buy an SSD mount and of course it’s impractical.
Check the slot on the laptop
Generally speaking, today’s laptops have two options for installing an SSD. Namely through the SATA slot or M.2 slot. Generally laptops provide 2 SATA slots, namely 1 for HDD and 1 for internal DVD RW. So you need to check the specifications of your laptop via the official website or application.
To add an SSD to a laptop, you need to sacrifice the DVD RW to be replaced with an HDD Caddy. Unlike laptops that have M.2 slots, you only need to buy an M.2 SSD type and install it directly on the motherboard.
And one more thing to note is that the M.2 SSD in this laptop has 2 types, namely M.2 SATA (regular) and M.2 MVMe which is faster. So make sure again which M.2 series supports the motherboard you are using.e
So that’s the difference between SSD and HDD on laptops and PCs in general. As the latest technology, SSD is certainly superior to HDD. But there is an option that you can use them together.
Where SSD is used to store the operating system to run faster and smoother and HDD to store various files and documents. All right, these short acticles and hopefully useful.
