Enterprise SSD for mixed-use servers

The HPE P18436-B21 is a 1.92 TB 2.5-inch SATA solid-state drive built for mixed-use workloads in server environments. It supports hot-plug installation and carries an endurance rating of 3.1 DWPD for sustained write performance.

SATA 600 interface throughput limit

The drive connects through a SATA 600 interface, which caps the maximum read transfer rate at 520 MB/s. This bandwidth ceiling defines the practical speed limit for any workload running on this device.

3.1 DWPD endurance rating

The 3.1 drive-writes-per-day figure is the single specification that determines whether this SSD matches the write intensity of your application. Buyers who need higher write endurance for heavy logging or caching should verify this rating against their workload profile.

Questions about this item

Is the 1.92 TB capacity the right choice for mixed-use server workloads?

Yes, the 1.92 TB model delivers 3.1 DWPD endurance, which is designed for mixed read and write workloads on supported server devices.

What does the 520 MB/s maximum read transfer rate mean once the drive is installed?

It represents the peak sequential read speed achievable over the SATA 600 interface under optimal conditions; sustained throughput will depend on the server controller and workload mix.

How does the SATA 600 interface cap real-world performance?

The SATA 600 link tops out at 6 Gb/s, so the 520 MB/s read rating sits near the practical ceiling of the bus; write speeds and random IOPS will be lower.
