If you are using Samsung SATA SSD, you can use Rapid Mode, which can make SATA SSD achieve over 2X faster performance through intelligent DRAM caching of data, for read acceleration and write optimization.īut how does the Rapid Mode do that? As we all know, you can't physically make the drive faster, as the read/write speeds are bound by the limitations of the hardware. Then, is there no way to improve the performance of SATA SSD? Of course, there is. It touches upon SATA Bus standard, PCI-E Bus standard, AHCI protocol, and NVMe protocol. This article explains deeply what SATA SSD and M.2 SSD are.
