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.
