What is an SSD hard drive?
First, SSD stands for “Solid State Drive,” which means solid-state storage drive or electronic, hard drive. SSD hard drives function like HDDs, but instead of having a magnetic coating on the surface, SSDs use flash memory chips that combine and save data even when the drive is not powered. SSD hard drives were created to replace traditional HDD hard drives. SSD improves data processing speed and security, saves power, and helps the machine be less hot.
Advantages and disadvantages of SSD hard drives compared to HDDs
Advantages:
SSD hard drive has a faster data access speed. Thus reducing startup time, application running time, increasing computer performance.
SSD is a solid-state drive, the memory chips are firmly fixed on the motherboard, so it is more resistant to shock. Reduce the risk of damage in the event of a collision.
SSD drives operate smoothly and dissipate heat better.
SSDs have a better appearance, as well as more design flexibility.
Defect:
SSD hard drives offer outstanding improvements over traditional HDDs. However, SSD drives make users wonder because of the disadvantages of cost. The price of an SSD hard drive is much higher than HDD.
For the same cost, you can only buy an SSD with a capacity of 128GB or 256GB, but you will get an HDD with a capacity of 512GB or even 1TB.
SSD drives have a limit on the number of data writes. However, with the needs of general use, it will take a long time for you to worry about this.
How many types of SSD hard drives are there for laptops?
Currently, there are four types of SSD hard drives with their advantages.
2.5 SATA SSD: 2.5 inch SSD hard drive, sharing the same SATA interface with HDD hard drive. Make it easy and cost-effective for users to upgrade their hard drives. 2.5 SATA SSDs also have 1.8-inch and 3.5-inch sizes but are less common. Theoretical speed is about 550MB/s.
mSATA SSD: Small size hard drive, using mSATA port. The hard drive still uses the standard SATA connection, but the port size is reduced – mini SATA.
SSD M2 SATA: This is an upgraded version of SATA SSD. SSD M2 SATA uses the new M2 interface to be compatible with increasingly thin and light laptops. The processing speed of SSD M2 SATA is 550MB/s.
SSD M2 PCIe: The hard drive uses the standard PCIe interface for processing speed six times faster than the standard SATA III, with a speed of about 3500MB/s. That is the hard drive that supports high-end laptops.
In which case should SSD hard drive be used?
With its advantages and disadvantages, SSD hard drives will be suitable for users who are often on the go and require fast processing speed. Currently, the price of hard drives on the market has dropped significantly. In addition, the appearance of dual hard drives with large capacity of HDD and fast processing speed of HDD. Therefore, it will be easy for you to decide which hard drive to choose to upgrade your laptop.
