Product Features
Technical Overview
This SSD connects via a SATA/600 (6 Gb/s) interface, providing optimized burst performance for data transfer. The 960GB capacity offers substantial space for operating systems, applications, and active datasets. Performance is quantified at 72,000 IOPS for random 4KB reads and 31,000 IOPS for random 4KB writes, ensuring responsive data access under load.
A key technical specification is its endurance rating of 3.4 Drive Writes Per Day (DWPD) under a mixed-use endurance profile. This metric indicates the drive can withstand the equivalent of writing its full capacity 3.4 times daily over its warranty period, making it suitable for environments with moderate to high write activity.
Relevant factors for this section include Storage Capacity, Random 4KB Read, Random 4KB Write, Endurance (DWPD). When those points are considered together, they give buyers a clearer picture of how the product is equipped, how it fits into deployment, and what kind of day-to-day role it is meant to support.

FAQ
What is the storage capacity and interface of this HPE SSD?
This HPE solid-state drive offers 960GB of storage capacity and uses a SATA interface, specifically the SATA/600 (6 Gb/s) standard. This combination provides a balance of substantial storage space for server applications and a reliable, widely supported interface for connectivity to server backplanes or controllers.
What does a 3.4 DWPD endurance rating mean for this drive?
A 3.4 Drive Writes Per Day (DWPD) rating indicates this SSD is endurance-rated for mixed-use workloads. It means the drive is designed to withstand writing its full 960GB capacity 3.4 times every day over its specified warranty period. This makes it suitable for server environments with moderate to high write activity, such as database transactions or virtual machine operations.
What are the random read and write performance specifications?
The drive delivers random 4KB read performance of 72,000 IOPS and random 4KB write performance of 31,000 IOPS. These metrics measure how many small, random input/output operations the drive can handle per second, which is critical for server responsiveness when running multiple applications or virtual machines that access data unpredictably.
Is this SSD hot-pluggable, and what are the benefits?
Yes, this HPE SSD is hot-pluggable. This feature allows you to install, remove, or replace the drive while the server is powered on and operating. The primary benefit is maintaining server uptime and availability, as you can perform storage maintenance or expansion without scheduling a full system shutdown, which is essential for critical 24/7 data center operations.
What server systems is this drive compatible with?
This drive is designed and validated for server use, with specific compatibility for HPE ProLiant rack servers. It is a multi-vendor SSD in a small form factor (SFF), meaning it is engineered to work within the drive bays and with the storage controllers of compatible HPE server platforms. Always verify specific model compatibility with your server's documentation.
What is the form factor and physical dimensions?
The drive uses a 2.5-inch small form factor (SFF) with a height of 7mm (0.28 inches). This slim profile allows it to fit into dense server drive trays. It includes a drive carrier for secure mounting. The approximate weight is 1.10 pounds (500 grams), making it a standard weight for enterprise-grade 2.5-inch SSDs.
