The Lenovo ThinkSystem 800GB P5800X NVMe PCIe 4.0 x4 Write Intensive 3.5" U.2 Hot Swap Solid State Drive is the ultimate in high performance storage with ultra-low latency, very high bandwidth, and an endurance of up to 100 drive writes per day, making this drive the best choice for write-intensive workloads. The P5800X has a PCIe 4.0 (Gen 4) host interface, where sequential performance is doubled over the PCIe 3.0 host interface. It is also fully compatible with a PCIe 3.0 host interface providing optimal performance and enabling compatibility across server families. Also NVMe is a technology that overcomes SAS/SATA solid state performance limitations by optimizing hardware and software to take full advantage of flash technology. Intel Xeon processors efficiently transfer data in fewer clock cycles with the NVMe optimized software stack compared to the legacy Advance Host Controller Interface (AHCI) stack, thereby reducing latency and overhead. It connects directly to the processor via the PCIe bus, further reducing latency and TCO.
