Capacity and interface

This HP 718189-B21 is an 800GB 3.5" SATA enterprise SSD built with MLC memory. It targets servers and storage arrays that need consistent read performance and high endurance for mixed workloads.

Compatibility check

Verify that your chassis accepts a 3.5" drive with a height of .38" and a SATA 6Gb/s backplane or controller. The unit weighs 100g and measures 3.45" wide by 2.75" deep, so confirm bay clearance and cabling before ordering.

Sustained workload behaviour

With a seek time of .1 ms the drive maintains low latency during continuous random I/O rather than only in short bursts. MLC flash and enterprise firmware keep write performance steady over long periods, and the refurbished unit carries a 90 day warranty.

Questions about this item

Does the HP 718189-B21 800GB 3.5" SATA enterprise SSD ship with a mounting bracket or caddy, or must I supply my own?

The drive is a bare 3.5-inch unit measuring .38" high, 3.45" wide and 2.75" deep; no bracket, screws or caddy are included, so you will need to provide whatever mounting hardware your server or storage array requires.

How do I decide between the available capacities for the HP 718189-B21 3.5" SATA enterprise SSD line?

The listed model is the 800GB variant; if your workload needs more space you would select a higher-capacity part number, while a lower-capacity part number suits smaller datasets or tighter budgets.

What does the 800GB rating mean for usable space once the HP 718189-B21 3.5" SATA drive is formatted in a server?

You will see roughly 800GB of raw capacity; after file-system overhead and any RAID parity the usable amount will be somewhat less, but the drive presents the full 800GB to the operating system.
