The way to distinguish the quality of SSD is judging surface logo, datailed information, actual test data and SSD quality.
7nm is the physical limit of silicon chips. The carbon nanotube composite materials replace silicon to make transistors below 7nm. 1nm process transistor is still in the laboratory stage. Technological advances do not necessarily bring commercial benefits. For the current Chinese semiconductor industry, it is better to use limited manpower and material resources to improve the IP library of 28nm...
AHCI and NVMe are two different ways of SSD transmission protocol. when the AHCI mode is turned on, the SSD reading and writing performance boosts. The NVMe protocol further enhance the actual reading and writing performance of SSDs and improve product transmission efficiency.
The BX500 has a performance degradation, with the main control scheme and the external DRAM cache smaller. The BX500 still retains the same second-generation 64-layer stacked 3D TLC flash memory as the MX500. When writing data into the disk, it shows a lower performance than others. Plastic shell is easy to accumulate heat it isn’t a suitable environment for chip working.
The capacity of Cache is generally very small, even the largest three-level Cache (L3) is only 20MB ~ 30MB. But the capacity of current memory is in GB as a unit. The CPU usually accesses the memory by reading and writing one word unit at a time. When the CPU fails to access the cache, it is necessary to loaded the word unit stored in main memory into the cache along with several subsequent words....
With the development of technology, mobile phone has become an indispensable mobile device at present, whose configuration has evolved from single-core to eight-core or even ten-core, making its functions more and more powerful. The high-end mobile phone upgraded the standard of storage chips from eMMC to UFS, and began to popularize in thousand-yuan smartphone models.
