Use and maintenance of SSD

For the use and maintenance of solid state drives, the most important one is that the "good habits" developed in the era of mechanical hard drives may not be suitable for SSD.


1. Small partitions and fewer partitions

It is also due to the "garbage collection mechanism" of solid state drives. Deleting files on the solid state drive completely destroys the entire area where the invalid data is located. The process is as follows: first collect the valid data in the area, move it to a free location, and then clear the "problem area" as a whole.


This mechanism means that the SSD capacity should not be fully allocated when partitioning. For example, a 128G solid-state hard drive, manufacturers will generally nominal 120G, reserved a part of the space. But if you only divide 100G when partitioning, leaving more space, the performance of the solid state drive will be better.


These reserved spaces are automatically used for optimization operations inside the SSD, such as wear leveling, garbage collection, and bad block mapping. This approach is called "small partition".


"Few partitions" is another concept, which is related to the impact of "4k alignment" on solid state drives. On the one hand, the capacity of mainstream SSD is not very large. More partitions means more wasted space. On the other hand, too many partitions can easily lead to partition misalignment, and the performance of the disk area at the partition boundary may be affected.


The easiest way to maintain "4k alignment" is to use the partitioning tool that comes with Win7 to partition, so as to ensure that the partitioned areas are all 4K aligned.


2. Reserve enough free space

The more SSD storage, the slower the performance. However, if a partition is used for a long time in a state of more than 90%, the possibility of some solid-state hard drives will be greatly increased, and most hard drives will also experience performance degradation.


Therefore, it is very important to clean up useless files in time, set an appropriate virtual memory size, and store large files such as movies and music on the mechanical hard disk. The solid-state hard disk partition must reserve enough remaining space.


3. Refresh the firmware in time

Portable SSD 

"Firmware" is like the BIOS on the motherboard, which controls all internal operations of the solid state drive, which not only directly affects the performance and stability of the solid state drive, but also affects its lifespan. Excellent firmware contains advanced algorithms that can reduce unnecessary writing of the solid state drive, thereby reducing the wear and tear of the flash memory chip, maintaining performance and extending the life of the solid state drive.


Therefore, it is very important to update the latest firmware officially released in time. Not only can it improve performance and stability, but it can also fix previous bugs.


4. Learn to use recovery instructions

The Trim reset command of the solid state drive can completely restore the performance to the factory state.


With the rapid development of the Internet, people's demand for data and information storage is also increasing. KingSpec also launched our own portable SSD. If you need it, you can check our website.
