Did you know?

NVMe (Non-Volatile Memory Express) is a technology that overcomes SAS/SATA SSD performance limitations by optimizing hardware and software to take full advantage of flash technology. The use of NVMe Flash Storage Adapters means data is transferred more efficiently from the processor to the storage compared to the legacy Advance Host Controller Interface (AHCI) stack, thereby reducing latency and overhead. These Flash Storage Adapters connect directly to the processor via the PCIe bus, further reducing latency and TCO compared to SAS/SATA SSDs.

Lenovo Enterprise Mainstream Flash Adapters are suitable for mixed read-write and general-purpose data center workloads, however their NVMe PCIe interface means the adapters also offer high performance. Overall, these adapters provide outstanding IOPS/watt and cost/IOPS for enterprise solutions.

• Low power consumption (maximum 18.5 W)


• Full Power-Loss-Protection and End-to-End Data Protection


• 3 drive-write-per-day (DWPD) endurance for mixed read-write workloads


• Based on the Toshiba PX04PMCxxx Add-in Card (AIC)


• 19nm MLC NAND (128 Gb/die)


• Half-high half-length PCIe adapter with PCIe 3.0 x4 host interface
