Description

ATP U.2 SSDs support the NVMe™ protocol on the high-speed PCI Express® (PCIe®) Gen4 x4 interface. Capacities range from 320 GB to 7.68 TB and can either be I-Temp (-40°C to 85°C: N751Pi/N651Si) or C-Temp (0°C to 70°C: N651Sc) operable to meet the varied usage requirements of embedded/industrial PCs, networking systems, and other function-critical segments.

The high-speed PCIe Gen 4 x4 interface offers twice the bandwidth of the previous generation, enabling the N751Pi/N651Si/N651Sc U.2 SSDs to transfer data faster. ATP’s PCIe Gen 4 SSDs use x4 lanes for a maximum bandwidth of 8 GB/s.

The 15 mm fin-type heatsink design offers effective heat dissipation to ensure optimal sustained performance.
