Compare SSD and HDD to find out which one is right for you
1. What is an SSD?
SSD (Solid State Drive) is a solid-state drive or solid-state drive, it is used as a device to store information and data. To make it easy to understand, SSDs are like familiar USB drives, just SSDs are a much larger and more complex container version than USB. It doesn't have a physical spinning drive inside, so usually the SSD will run quite quietly, not making any noise.
The operating principle of SSDs is based on NAND Flash chips, it does not use conventional information storage mechanical structures and does not store data on mechanically active platters.
The structure of NAND Flash used in SSDs includes many floating gate transistors that are special transistors that do not need to be refreshed many times per second when used like in the transistor used in DRAM memory. And it is also capable of remaining in the same state even in times when it is not powered. The organization and operation of NAND Flash is in the form of a grid, consisting of many blocks and pages. Page is made up of many cells, and many pages will form a block.
2. What is HDD?
HDD (Hard disk Drive), also known as hard disk drive, is a specialized device for storing data on the surface of circular disks covered with a magnetic material. HDDs are also known as "immutable" storage devices because they have the ability to maintain data storage even when the power is off. HDDs will typically be installed inside desktop mobile devices, consumer electronics, etc. They can store operating systems, software programs, and other files using magnetic disks.
HDD is a popular storage device today
The organizational structure and operation of HDD is different from SSD. They are divided into tracks, sectors and clusters. Sectors are radial lines divided by each track. Many sectors will form a cluster. When a hard drive fails, the track is the only part that can be reconstructed and repaired and reused.
3. Compare SSD and HDD
To better understand these two types of hard drives that store data, let's see Compare HDD and SSD The following:
3.1. About the storage capacity
HDD often has many types with large storage capacity, up to several Terabytes, but the price is quite soft. SSDs tend to be much smaller in capacity but more expensive.
3.2. About data write/read speed
- The rotation speed to record information of the HDD usually runs at 5400rpm to 7200rpm, with such a rotation speed will give the SSD's data read/write capacity about 200MB/s. Reading data files will be faster if files are stored in adjacent sectors.
- SSD's data write / read speed is much faster, can reach 500 MB / s, thanks to the powerful NAND Flash chip, much faster memory. These chips also have the ability to work right from the start, making work faster.
Thanks to the NAND chip, SSD hard drives are faster
3.3. About durability
SSD hard drives are much more resistant to physical impacts than HDDs. Because of the mechanical structure, HDD hard drives are easily affected and damaged. Therefore, when using an HDD, you should not leave it in a harsh environment.
SSDs have better heat resistance, so they can work in harsh environments. SSD repair and recovery is also easier with HDD.
3.4. About data fragmentation
HDD will be prone to data fragmentation, while SSDs use discrete chips, so there will be no fragmentation on SSDs.
3.5. About power consumption and noise level
HDD consumes more power and also makes more noise than SSD
3.6. About form
HDD is usually only produced in two forms, 2.5 inches and 3.5 inches, but SSDs come in many different forms and sizes.
3.7. About the selling price
The cost of HDD is usually much cheaper than SSD.
4. What type of hard drive should I choose?
After having Compare SSD and HDD We see that depending on the purpose and usage needs, users will choose HDD or SSD hard drive.
If you need to store a large amount of information, you should not use an SSD because the amount of money to spend to buy a high-capacity SSD is very large.
Should use HDD if you need a cheap drive with a large capacity
People who should use SSDs are those who travel a lot while working, or those who need to have high data and information processing speed such as people working in the field of graphics or engineers.
After having Compare SSD and HDD About the characteristics and differences and benefits of each hard drive, hopefully you have been able to choose the right hard drive for your work. If you want to learn more about hardware, visit Mat Bao for more useful information!
