This is a question that many customers have asked us recently? HDD and SSD are the two most popular types of storage devices today. HDD (Hard-disk-drive) is a traditional hard drive and SSD (Solid-state-drive) is a new technology hard drive in solid-state form. Basically, both types of hard drives are used to store data, so many users often confuse SSD and HDD hard drives. So what’s the difference between SSD and HDD? When should I use SSD/HDD for each specific purpose?

Price of SSD and HDD for industrial computers

Traditional HDDs cost much less than modern SSDs. Although the price has decreased compared to the beginning, these SSDs are still 3 or even 4 times more expensive than HDDs with the same storage capacity. For example, for a 500GB drive, you only have to pay 500,000 (VND) for a 2.5 inch HDD, but for an SSD it will be 1,400,000 (VND).

Write and read speed of SSD and HDD

SSD hard drives have superior read and write speeds compared to HDDs, the easiest way to recognize them is through a very fast computer boot process. 

An industrial computer using an SSD only takes a few seconds to a few tens of seconds to boot, while using an HDD will take about 1 minute or more, this speed is also true for tasks on the computer. , use graphics or play games. 

The current read and write speed of SSD will be from 80MB – 300MB, some specialized SSD devices such as SLC will be up to 800MB, with HDD it is about 100MB. However, if you need to store instead of experiencing speed, you should choose HDD because an HDD has many times more storage capacity than an SSD in this price range.

Hard drive fragmentation between SSD & HDD

An HDD is a metal disk covered with a magnetic layer used to store data. When the spinning drive starts spinning, a metal bar inside it will have the function of reading and writing data. 

Fragmentation occurs when data is scattered across the surface of the spinning disk. But with an SSD hard drive, it will be different. Inside this SSD are flash memory chips linked together, so they will definitely be less fragmented than an HDD and work better.

Durability of 2 types of hard drives

SSD will use electronic devices as memory, so when you use SSD, data will be transferred to SSD directly, in addition, HDD always rotates the disk sides to write data. 

Therefore, in some cases where you drop your computer backpack or your system is shaken by an earthquake while it is operating, you can feel more secure when using SSD. Furthermore, the operating time and durability of SSD are also considered to be much longer than HDD.

Noise of SSD and HDD

HDD manufacturers have tried to make their HDDs operate as smoothly as possible, but after a long time of use, it is difficult for HDDs to avoid noise when reading. and write to the disc surface. In contrast, an SSD hard drive makes almost no noise when operating, because it does not have much metal structure.

Power consumption between SSD and HDD

Because it does not need additional power to rotate on the disk surfaces, SSD hard drives consume very little power. Compared to HDDs, SSDs consume four times less power.

Above are the differences between HDD and SSD used for industrial computers. It can be seen that SSD is a more optimal choice if you have enough money to serve your working needs. , entertainment with data retrieval, combined with longer durability.
