Connectivity and compatibility

This SSD connects through a SATA 6 Gb/s interface, ensuring compatibility with a wide range of servers and storage systems that support this standard. It is specifically qualified for HPE compute platforms, including ProLiant servers, which simplifies deployment and integration in enterprise data centers and branch offices.

Performance and reliability

With a focus on read intensive tasks, this drive maintains high responsiveness even when multiple virtual machines or web sessions are active. The firmware validation feature adds a layer of security by preventing unauthorized code execution, while the Smart Carrier enables quick maintenance without interrupting server operations. Its endurance rating and power efficiency make it a dependable choice for environments where read speed and reliability are critical.

Ideal uses and environments

This SSD fits well in corporate data centers, branch offices, and lab environments where read-heavy workloads dominate. It is a strong choice for front-end web nodes, content delivery servers, and database replicas that require fast access to data without the need for large storage capacity. Its low power consumption and small size also make it suitable for dense compute racks and edge deployments where space and energy efficiency are priorities.

Some items are not returnable: opened TVs/combos/monitors 37″+, opened computers or software, electronic downloads, opened consumables (film, paper, bulbs, media, ink), custom or modified computers, special-order or “nonreturnable” items, submerged underwater gear, and opened educational media.

After inspection, refunds are issued to the original payment method; allow 5–7 business days for the credit to post. Shipping, handling, customs duties, and import taxes are nonrefundable. If an item is used, incomplete, or not in original condition, a 30% restocking fee may apply. Direct exchanges are not offered; purchase the replacement and return the original for a refund.

We act solely as a reseller. Any product warranty is provided and administered by the manufacturer, not by our store. That means eligibility, coverage, and outcomes are determined by the manufacturer’s policy for each brand and model. Before purchasing, we recommend reviewing the warranty terms on the manufacturer’s website or in the product documentation to confirm what is covered and for how long.

If you need warranty service, please file the claim directly with the manufacturer. They may require proof of purchase, the product serial number, original packaging, photos, or basic troubleshooting. Some brands ask you to register the product or obtain a case number before shipping it for repair or replacement. We don’t submit or approve claims, but we can point you to the correct support links and contact details.

Keep your invoice and packaging in a safe place, and report any functional issues to the manufacturer as soon as they appear. If you’re unsure whether a problem is covered, the manufacturer’s support team can confirm next steps and timelines. While we cannot intervene in decisions or outcomes, we’re happy to provide purchase documentation or guidance so you can move through the warranty process smoothly.
