As a hard disk using NAND as storage medium, SSD is ten times faster than traditional disc mechanical hard disk theory. Upgrading from mechanical hard disk(ssd) to solid state hard disk can greatly improve the speed of computer on/off, the speed of software loading and the fluency. However, some netizens often say that after upgrading the solid state hard disk, their computer does not feel faster or slower. What’s wrong? Next, let’s get your computer in control!

The importance of properly installing SSD interfaces is ignored

If you are using a laptop, make sure that the extension interface of the motherboard provides SATA 2, SATA 3, or M.2 interfaces, which directly affects whether the SDD you add will run at normal read/write speed. Generally, the reading and writing speed of SSD of SATA3 interface can reach about 500 MB/s, and can only reach up to 300 MB/s on SATA2. The theoretical speed is nearly twice as fast, so it is necessary to pay attention to the correct corresponding interface when adding SSD to the computer.


Some users like to take their notebook’s CD-ROM drive apart and transfer it to a hard disk, but many notebooks have only SATA 2 as the CD-ROM interface, which can make it less effective to install a solid-state hard disk. Due to the speed limit of the interface, high-speed SSD speed cannot be used. Half of these users are advised to change the installation location of the CD-ROM drive to the secondary drive (mechanical hard disk) and the hard disk to the SSD when installing SSD.

In addition, many new notebooks are now equipped with M.2 interface. When installing M.2 interface SSD, users also need to see if the interface supports PCI-E channel. The relevant NVMe drivers need to be installed correctly to avoid unstable data reading and machine jamming.
What interfaces and protocols are supported by the motherboard can generally be consulted in the product description. PC Xiao Bai suggests choosing the latest Core 8th Generation notebook or using Z300 Series Chip notebook, which upgrades the SATA 3 interface completely and supports the NVMe M.2 interface SSD. It is very convenient to install the driver automatically under Win10 operating system.

Common data is not installed on SSD disks


solid state drive don’t end up on your computer, and the speed at which data is read still depends on where you save the source address. When multiple hard drives are mixed and matched, for example, SSD + HDD is often chosen. If the data is still stored in HDD, it is still futile.
Solution: Reload the system and migrate the data using the newly installed SSD

The capacity of SSD is too small


To improve lifetime, SSDs(ssd) are usually erased only after the data has been fully written to its maximum capacity once, but when this process occurs, the performance of SSDs can be severely affected. Therefore, if the capacity is insufficient and often needs to be erased, the effect will be discounted.
Solution: Select large capacity SSD.

SSD are not optimized, such as no 4K alignment


Solid state hard disk 4K alignment is very important. The so-called 4K alignment actually refers to 4K advanced formatting, which requires 4K alignment of hard disk sectors. The 4K Advanced Formatting Standard specifies that the hard disk sector size is migrated from the current 512 bytes to 4096 bytes (or 4K). This change will improve formatting efficiency, which will help the hard disk to provide higher capacity while providing improved error correction.
When partitioning, it is important to check the 4K alignment. If you find that your SSD does not have 4K alignment, you can search for and download the software Paragon Alignment Tool above to make a lossless 4K alignment for your SSD.
These are the reasons and solutions for whether your computer is slow with a solid state hard disk, especially the 4K alignment problem. After checking these problems, users are confident that the speed will be greatly improved so that your computer can fly smoothly.
