The SSD’s interface (e.g., SATA, USB, PCIe) impacts speed. Check if the connection supports the SSD’s full bandwidth, as older interfaces (like SATA II or USB 2.0) may throttle performance. For maximum speed, ensure you’re using a compatible high-bandwidth port, such as SATA III for SATA SSDs or a PCIe slot for NVMe SSDs.
