There are three main types:
· SATA SSD (2.5-inch): The most universal, using a SATA interface, with speed and form factor compatible with older HDDs. Suitable for upgrading older computers, with a maximum speed of approximately 550MB/s.
· M.2 NVMe SSD (M.2 form factor): Currently the mainstream high-performance choice. Connects directly to the CPU via the PCIe channel, offering speeds far exceeding SATA. Before purchasing, please ensure your motherboard supports the M.2 interface and NVMe protocol.
· PCIe SSD (extension card): Typically used in high-end desktops or workstations, offering top-tier performance.
Purchase Recommendation: For new computer builds or those seeking ultimate performance, M.2 NVMe SSDs are the first choice. For easy upgrades to older computers, SATA SSDs are an option.
