800GB SATA 6.0Gb/s internal SSD

This HP 691842-004 provides 800GB of solid-state storage in a 2.5 inch form factor. It connects through a SATA 6.0Gb/s interface for broad server and workstation compatibility. The drive is supplied as a bare unit with a Smart Carrier tray for tool-less installation.

Sustained write behaviour

The SATA 6.0Gb/s link sets the maximum transfer ceiling for continuous workloads. Average latency is specified at 6Gb/s, indicating consistent throughput during extended write sequences. Without a separate DRAM cache figure the controller manages steady-state performance within the interface limit.

Smart Carrier build and connectors

A Smart Carrier tray integrates the drive into supported HP bays without screws or caddies. The 2.5 inch metal housing protects the PCB during handling and hot-swap operations. Standard SATA data and power connectors align with the carrier for reliable mating cycles.

Questions about this item

How much power does the 800GB SATA 6.0Gb/s SSD draw during continuous operation?

The 2.5-inch SATA drive consumes low power typical of solid-state storage, generating minimal heat during all-day workloads.

What drive bay or carrier does the HP 691842-004 need to fit a server?

It ships as a bare 2.5-inch drive with a Smart Carrier tray that slides directly into compatible HP drive bays.

Will this 6Gb/s SATA SSD work in an older 3Gb/s backplane without changes?

Yes, the SATA 6.0Gb/s interface negotiates down to 3Gb/s automatically, so the drive functions on legacy controllers.
