his is an internal solid-state storage drive in the M.2 form factor, with 1 TB of capacity. It uses flash memory to store data and connects to your computer’s motherboard via the M.2 slot. Based on listings and the “SK-800” name, it’s a budget NVMe SSD — likely NVMe over PCIe or SATA-based M.2 but not a high-end model like current PCIe Gen3×4 or Gen4 drives. A benchmarking registry entry for an SK800-1TB shows sequential read/write speeds around 529 MB/s read and 495 MB/s write, indicating SATA--like performance or a lower-end NVMe implementation rather than the very fast PCIe Gen3/Gen4 speeds seen in premium drives.
