Product details

This SSD transfers data using PCI-Express, which puts it far ahead of traditional SATA SSDs in terms of transfer rates. M.2 SSDs are installed via the M.2 socket on the motherboard. Due to their compact dimensions, they are particularly suitable for use in ultrabooks and mini-PCs, but can also be used in standard computers. This SSD shines especially in systems with NVMe support. Users benefit from high throughput, high IOPS, and low latency. Unlike the older AHCI protocol, which was designed for traditional spinning drives, NVMe prevents performance drops, offers faster transfer of large data volumes, increased boot speeds, and improved system responsiveness.
