Learn The Pros And Cons Of SSD Hard Drives Compared To HDD

Overview of SSD and HDD Hard Drives

Before learning about the advantages and disadvantages of SSD hard drives compared to HDD, we must have an overview of these two types of hard drives. First, about the concept of hard drives, we can simply understand that this is an extremely important part of the computer. All information and data will be stored in the hard drive. If there is any damage or any problem, it will be very difficult for you to recover lost data.

HDD hard drive

HDD stands for Hard Disk Drive . This is a traditional hard drive, made from a round disk made of aluminum, glass or ceramic coated with a layer of magnetic material. The operating principle of the HDD is as follows: the motor rotates the drive to read/write data, the circuit board will automatically control the read/write head to the correct position on the rotating drive to decode the information.

The rotation speed of the drive will affect the data copying process as well as the operations on the computer. In addition, the better the material of the components in the hard drive, the safer the data on your computer. Currently on the market, HDD hard drives have 2 rotation speeds: 5400 RPM (revolutions per minute) and 7200 RPM (revolutions per minute).

SSD hard drive

SSD (Solid State Drive) is also known as semiconductor hard drive, electronic hard drive. This is a type of hard drive that uses Flash memory chips to store data. These flash chips will be fixed on the computer's system motherboard. The operating principle is similar to memory cards or USB. Although both use chips, the memory chips in SSD hard drives are often faster and more reliable than USB memory chips.

Therefore, the recovery price of SSD hard drives is much higher than that of USB drives with similar functions. The data processing speed of SSD hard drives can be up to 32 Gbps. Not only is it faster in speed, but SSD hard drives have a high level of safety, and their size and power consumption are also very small. Therefore, SSD hard drives become formidable opponents of traditional drives.

Advantages and Disadvantages of SSD Hard Drives Compared to HDD

Advantage

About speed: Operating based on Flash chip, SSD hard drive does not have mechanical operations, so performance is greatly increased. This is also the superiority of SSD compared to HDD.

Faster, more efficient data retrieval, data stored consecutively and no hard drive fragmentation.

HDD hard drives operate mechanically, containing many solid objects, so when a strong impact occurs, it will be damaged and it is very difficult to recover data. But SSD hard drives limit this problem, so the data has a longer lifespan.

Depending on mechanics, HDD hard drives are quite large in size. When operating, they create noise. But SSD hard drives are made of memory chips and circuit boards, so they are very small in size and do not make any noise at all.

Disadvantages

Although it has many advantages over HDD , the biggest disadvantage of SSD is probably the high price. Currently, a 128GB SSD costs between 1.2 million and 2 million VND. To put it simply, when you use and store 1GB of data, you have to pay between 10,000 and 20,000 VND. This will be a very high cost when compared to HDD because 1GB of this hard drive is only about 2,000 VND.

An equally important drawback to deciding which type of hard drive to use is the capacity. Until now, SSD hard drives mainly only meet storage needs with a capacity of 128 GB or 256 GB . With such a capacity, it only meets the needs of ordinary users. If you want a larger capacity SSD hard drive ( over 512GB to 1TB ), the cost will be extremely high.

Should I Choose SSD Or HDD?

After knowing the advantages and disadvantages of SSD hard drives compared to HDD, you are wondering which type to choose. If you are someone who needs a lot of storage capacity but does not want to spend too much, choose HDD hard drives. But if you want your computer to have faster performance, more secure data, and run many heavy software, you should choose SSD.
