Workload Endurance & Performance Data

Mixed Use drives are designed for environments with heavy read/write mixed workloads, offering robust endurance typically rated at 3 DWPD (Drive Writes Per Day) over a 5-year period.

Endurance Total Bytes Written (TBW): ~2,190 TB
Random Reads (4KiB): Up to 108,000 IOPS
Random Writes (4KiB): Up to 47,000 IOPS
Sequential Reads (128KiB): Up to 1,075 MB/s
Sequential Writes (128KiB): Up to 1,025 MB/s

Core Technologies & Features

HPE Smart Carrier (SC): Features self-describing LEDs that communicate the status of the drive (activity, online, predictive failure, do-not-remove status). This prevents accidental drive removal while data is being written.
Digitally Signed (DS) Firmware: Provides an extra layer of security by ensuring all drive firmware comes from a trusted source (HPE). It actively prevents malicious attacks, unauthorized firmware modifications, and accidental corruption.
Dual-Port High Availability: Utilizes dual-port SAS architecture to provide redundant data paths, ensuring no single point of failure between the server backplane/controller and the drive.
