HPE 400 GB SLC SAS SSD

This HPE solid-state drive provides 400 GB of storage using Single Level Cell flash technology. It connects through a 6Gb/s SAS interface in a 2.5-inch internal form factor. The drive is designed for extreme operating environments and local boot scenarios.

Suited for ProLiant blade servers needing reliable

The SLC NAND delivers faster reads and lower power draw than traditional rotating drives. It fits a limited selection of HPE ProLiant server blades. Buyers requiring higher capacity storage or drives for non-HPE platforms should look elsewhere.

6Gb/s SAS interface determines compatibility

The drive uses a SAS connection running at 6Gb/s, so the host system must provide a matching SAS backplane or controller. Without that specific interface the drive cannot be installed or used.

Questions about this item

How long will the SLC NAND flash in this 400 GB drive last before it needs replacement?

SLC flash typically endures far more write cycles than MLC or TLC, so the drive is rated for heavy write workloads over its service life.

What limits performance first when the 6Gb/s SAS link runs continuously at full speed?

The 6Gb/s SAS interface sets the maximum sustained throughput ceiling for the drive.

How much heat and power does the 2.5" SLC SSD produce during all-day operation?

Solid-state design with SLC NAND draws less power and generates less heat than mechanical drives of the same form factor.
