Difference between cached and uncached SSDs

The main differences between cached and uncached SSDs are read performance, price, and power consumption.

1. Read performance: The read performance of an SSD with a cache is usually better than that of an SSD without a cache. This is because a cache can speed up an SSD when it is processing a large number of small files and random read/write operations, and the performance gap between an SSD with a cache and one without a cache may be smaller when it is processing large files and sequential read/write operations.

2. Price: SSDs with cache are typically more expensive due to the cost of the cache chips, and in particular, SSDs with DRAM cache and true SLC cache can be significantly more expensive than SSDs without cache.

3. Power consumption: SSDs with cache can be slightly more power-efficient than SSDs without cache, as the cache chips require additional energy to maintain operation; however, this difference is usually negligible in real-world applications.

Solid State Drive Tips

1. Enable AHCI Mode: SSDs can perform better in AHCI mode, so you need to enable AHCI mode, which can be enabled in Windows in the Device Manager.

2. 4K Alignment: For SSD, 4K alignment is very important, if it is not aligned, it will seriously affect the performance and service life of SSD, you can use partitioning software or the tool that comes with SSD to perform 4K alignment.

3. Disable defragmentation: Since SSDs have no mechanical parts, they don't need to be defragmented. In Windows, you can disable the hard drive defragmentation program that comes with the system to improve the life and performance of SSDs.

4. Avoid frequently writing to the same piece of data: Although SSDs are more durable than traditional mechanical hard disks, too many write operations may reduce their lifespan, so avoid writing to the same piece of data as often as possible over and over again.
