800 GB SAS mixed-use drive

The HPE P49046-B21 is an 800 GB solid-state drive built for 12 Gb/s SAS infrastructure. It targets mixed-use workloads such as analytics, databases and virtualisation in server and storage arrays. The 2.5 inch form factor fits standard SFF bays and the drive is supplied new.

Enterprise endurance and data protection

Rated at 3 DWPD the drive sustains heavy daily write cycles without thermal throttling in typical chassis airflow. Full data-path error detection and surprise power-loss protection preserve data integrity during unexpected outages. Power draw remains within normal enterprise SSD limits for the platform.

2.5 inch SFF connector layout

The single-port SAS connector and standard SFF dimensions allow direct insertion into hot-plug backplanes without adapters. Self-encrypting FIPS capability secures data at rest when the feature is enabled. Firmware is managed through the host server tools already used for other HPE drives.

Questions about this item

How do I install the 2.5" SAS 12Gb/s SSD in a server drive bay and what step is often missed?

Slide the drive into an available 2.5-inch hot-plug bay until the carrier clicks, then verify the SAS link negotiates at 12Gb/s in the controller BIOS — skipping the link-speed check is the common oversight.

What maintenance or replacement will the 800GB TLC drive need after its rated endurance?

At 3 DWPD the drive is warrantied for its full write life; once that threshold is reached the SSD should be replaced rather than repaired, as TLC NAND wear is not field-serviceable.

What limit appears first when the drive sustains heavy mixed-use I/O?

The 3 DWPD endurance rating is the governing ceiling — continuous write workloads that exceed this daily budget will trigger wear-leveling throttling before thermal or interface bottlenecks occur.
