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. For a consumer, the most common options are SATA and M.2. SATA is known as the old two-connector system that hard drives used, including a SATA Power and SATA data cable. SATA-based SSDs are best for older computers that lack newer SSD connector types and have only SATA connections. 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. 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.
