The AHCI controller was never intended for use with SSDs, where the NVMe controller was built specifically with SSDs only in mind. AHCI as a controller also provides a bottleneck to SSDs in the form of latency the same way the SATA bus provides a bandwidth bottleneck to an SSD. AHCI is the controller that Hard Drives traditionally use to interface between the SATA bus of a Hard Drive and the computer it is connected to. NVMe, or Non-Volatile Memory Express, is a new controller used to replace AHCI, or Advance Host Controller Interface. However it should be noted that these SATA drives are capped at a maximum theoretical transfer speed of 600MB/s, whereas other un-bottlenecked SSDs have recently exceeded 3GB/s, nearly five times the SATA maximum. This means SATA-based SSDs cannot utilize the speed and efficiency of newer controllers such as NVMe. A great way to boost the speed of an older computer with a spinning hard drive is to clone the drive to an SSD, and replace the Hard Drive with an SSD, increasing the computer’s ability to read/write data, possibly by tenfold. SATA-based SSDs are best for older computers that lack newer SSD connector types and have only SATA connections. SATA is known as the old two-connector system that hard drives used, including a SATA Power and SATA data cable. For a consumer, the most common options are SATA and M.2. There are several connector types that SSDs use to interface with a computer, including SATA, PCIe, M.2, U.2, mSATA, SATA Express, and even none, as some SSDs now come soldered to the board. But there are countless options available, so what is the best drive?
