More Information

The PBlaze7 7940 Series NVMe SSD adopts PCIe 5.0 interface and supports NVMe 2.0, delivering 2.5 times the performance and 1.5 times the power efficiency compared to conventional PCIe 4.0 SSDs. This exceptional performance enables it to meet the growing storage performance demands for cutting-edge digital technology applications.

PCIe 5.0 High Performance: Developed on MUFP, the PBlaze7 7940 series achieves up to 2,800K IOPS for 4K random read and 720K IOPS for write. Sequential read and write performance reaches 14GB/s and 10GB/s respectively, with reduced latency to 57/9μs for consistent QoS.

High-Capacity and Diverse Form Factors: Available in capacities from 3.2TB to 30.72TB in 2.5-inch U.2, E3.S, E1.S, and HHHL AIC form factors for compatibility with diverse deployment environments.

Optimal Power Efficiency: Delivers up to 970MB/s sequential read performance per watt with dynamic power control ranging from 12W to 25W.

Enterprise Features: Upgraded to NVMe 2.0 and OCP 2.0 specifications with NVMe-MI 1.2b, end-to-end data protection, 128K Write Atomicity Normal, ARP, AES 256 encryption, sanitize, power failure protection, and secure boot.
