Seven years ago, we launched the first SSD to achieve 1 million IOPS in 4K random read performance. Today, we are once again setting a new benchmark by achieving 1 million IOPS for 4K random writes, making the PBlaze7 7A40 the best product we have ever made.
As the latest member of the PBlaze product family, PBlaze7 7A40 is developed based on the MUFP, with deep optimization of hardware and firmware, it delivers 3,300K IOPS for 4K random reads and 1,000K IOPS for 4K random writes, respectively, which is 3x and 2.5x the performance of maintain PCIe 4.0 SSDs. The sequential read and write speeds are 14.2GB/s and 11.3GB/s, leading the enterprise PCIe 5.0 SSD market.
The PBlaze7 7A40 leverages its controller architecture to reduce latency significantly by optimizing the I/O path, streamlining processing flows, and enhancing data layouts. This results in a 4K random read latency as low as 55μs and a random write latency of 5μs. Additionally, with enhanced flow control and intelligent sequential flow prefetch technology, its sequential read latency can also be as low as 6μs, boosting performance under low workloads and providing stronger support for various latency-sensitive business applications.
The PBlaze7 7A40 offers a 110% improvement in 4K random read performance per watt and a 73% increase in 4K random write performance per watt compared to its predecessor products. It consumes 13W for sequential reads and 18W for sequential writes, with an optimized thermal design to minimize thermal impact in dense deployment scenarios.
The PBlaze7 7A40 supports NVMe 2.0 and NVMe-MI 1.2b protocols, providing essential enterprise-grade features such as full data path protection, power-loss data protection, firmware upgrade without reset, secure erase and so on.
