What causes embedded storage to be slow?

  Slow embedded storage may be due to the following reasons:
  1. The installation interface is incorrect
  First make sure that the expansion interface of the motherboard provides a SATA 2, SATA 3 or M.2 interface, which directly affects whether the SSD you install can run at normal read/write speeds. Generally, the read and write speed of the SATA3 interface can reach about 500MB/s. On SATA2, it can only reach up to 300MB/s. The theoretical speed is nearly twice as fast. Therefore, when installing embedded storage, you must pay attention to the correct corresponding interface.
  Which interfaces and protocols the motherboard supports can generally be found in the product description.

  2. Commonly used data is not installed in the embedded storage disk
  Embedded storage is not installed and finished. The data reading speed still depends on the source address where you save it. When multiple hard drives are mixed and matched, for example, people usually choose a combination of SSD + HDD. If the data is still stored in the HDD, it is still in vain.
  Solution: Use the newly installed SSD to reinstall the system and migrate the data
  3. The capacity of embedded storage is too small
  In order to increase the lifespan, SSD is usually erased only after the data is completely written to the maximum capacity. However, when this process occurs, the performance of SSD will be seriously affected. Therefore, if the capacity is not enough and frequent erasing and writing is required, the use effect will definitely be compromised.
  Solution: Choose large-capacity embedded storage.
  The number of large-capacity erasing and writing will not be so frequent, the main control uses more channels, and the performance in speed is stronger.
  4. The embedded storage is not optimized well, such as not having 4K alignment.
  4K alignment of embedded storage is very important, and the so-called 4K alignment actually refers to 4K advanced formatting, which requires 4K alignment of hard disk sectors. The 4K Advanced Format standard stipulates that the hard disk sector size will be moved from the current 512 bytes to 4096 bytes (or 4K). This change will make formatting more efficient, helping the drive deliver higher capacity while providing improved error correction.
