Product Features
Technical Overview
This drive employs a 12Gb/s SAS interface that supports full-duplex communication and point-to-point connectivity, providing dedicated bandwidth for each connected device. The 15000 RPM spindle speed reduces latency for random access operations, while the 128MB cache optimizes sequential read/write performance for large data transfers.
The 3.5-inch form factor follows the LFF (Large Form Factor) standard commonly used in enterprise server and storage arrays. Hot-swap functionality allows for drive replacement while the system remains operational, supported by the SAS interface's native hot-plug capability and enterprise storage controllers.
Relevant factors for this section include Storage Capacity, Spindle Speed (rpm), Buffer. 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 HP server models is this drive compatible with?
This drive is specifically compatible with HP ProLiant ML110 Gen10 (G10), ML30 Gen10 (G10), and ML350 Gen10 (G10) server models. These compatibility details ensure proper physical fitment, interface support, and firmware compatibility within HP's server ecosystem.
What is the advantage of 15000 RPM spindle speed?
15000 RPM spindle speed significantly reduces rotational latency compared to lower-RPM drives, resulting in faster random access times for applications that frequently read and write small files. This makes the drive particularly suitable for database servers, virtualization hosts, and other performance-sensitive workloads where storage responsiveness is critical.
How does the 12Gb/s SAS interface compare to SATA?
The 12Gb/s SAS interface provides higher bandwidth than typical SATA interfaces (which commonly operate at 6Gb/s), supports full-duplex communication (simultaneous read/write operations), and includes enhanced error correction features. SAS is designed for enterprise environments where data integrity, performance consistency, and reliability are priorities over maximum capacity per dollar.
What does 'hot-swap' capability mean for this drive?
Hot-swap capability allows you to remove and replace this drive while the server remains powered on and operational. This feature requires compatible server hardware (backplane and controller) and enables maintenance, upgrades, or failed drive replacement without taking the entire system offline, which is essential for high-availability server environments.
What is the purpose of the 128MB cache buffer?
The 128MB cache buffer acts as high-speed memory that temporarily stores frequently accessed data or data waiting to be written to the platters. This improves performance for sequential read/write operations and helps manage the difference between the drive's mechanical speed and the interface speed, resulting in more consistent overall performance.
Is this drive suitable for RAID configurations?
Yes, this SAS drive is well-suited for RAID configurations due to its enterprise-grade design, consistent performance characteristics, and native support for RAID features through SAS controllers. The 15000 RPM speed and 12Gb/s interface make it appropriate for RAID 1, 5, 6, or 10 arrays where performance and/or redundancy are required for critical data storage.
