In the past ten years, the performance of the CPU has increased by more than 100 times, while the traditional HDD hard disk (Hard Disk Drive) has only increased by less than 1.5 times. This uneven computing and storage technology development has greatly affected the IT system The overall performance improvement. Until the solid state drive SSD (Solid State Drive) was invented, its performance has been subversively improved, and the storage bottleneck problem was solved. However, as a new technology, SSD still has some inherent shortcomings. How to give full play to the advantages of SSD is a direction worth studying. Let's do some discussion on this topic from the aspects of performance, durability, and cost of use.
