HDD Hewlett Packard Enterprise 300GB 2.5 DP SAS DG0300BARTQ

The Hewlett Packard Enterprise 300GB 2.5 DP SAS DG0300BARTQ is a 10,000 RPM enterprise-class hard disk drive designed for server and storage array environments. With a 2.5-inch small form factor and dual-port SAS connectivity, this drive targets applications that require consistent read/write performance, low latency and reliable operation under sustained workloads. The 300GB capacity balances density and performance for mixed-use tiers in data centers and virtualization platforms.

Advantages

This HDD delivers high rotational speed for faster seek times and improved I/O responsiveness compared with lower-RPM drives. Dual-port SAS provides redundant host paths and improved connectivity options in multipath storage architectures, while the 2.5-inch form factor allows for higher drive density in standard server enclosures. The drive is built to meet enterprise reliability expectations for continuous operation in racks and arrays.

Suitable for

• Enterprise servers and storage arrays requiring 10K performance
• Virtualization hosts and mixed workload environments
• RAID configurations where redundant paths and consistent performance are needed
• Applications with frequent random reads and moderate write activity

When it may not be suitable

This 10K SAS HDD may not be the best choice for archival or cold storage where low cost per GB and low power consumption are priorities; high-capacity, lower-speed SATA drives are usually more appropriate there. It may also be less suitable for workloads that demand the lowest possible latency and highest IOPS at any cost, where NVMe SSDs would provide substantially better performance.

Key specifications

• Capacity: 300 GB
• Form factor: 2.5-inch (small form factor)
• Rotational speed: 10,000 RPM
• Interface: Dual-port SAS (Serial Attached SCSI)
• Target use: Enterprise/server storage

How to use

Install the drive into a compatible 2.5-inch SAS bay or tray in a server or storage enclosure, ensuring the host or controller supports dual-port SAS connections and the drive's 10K rotational speed. Configure RAID, multipath I/O, or host-level storage policies according to your environment. Monitor drive health and firmware compatibility through existing management tools and replace or reseat the drive following vendor procedures when servicing is required.

What to consider before purchase

• Compatibility with server backplane, SAS controller and enclosure
• Intended workload profile (random vs sequential I/O) and required IOPS
• Cooling and power requirements in your rack or chassis
• Whether SSDs or higher-capacity SATA drives are more appropriate for your use case

Usage recommendations

Use this 10K dual-port SAS drive in tiers where a balance of performance, reliability and drive density is required. Pair with RAID and multipath configurations to maximize availability and maintain consistent performance under enterprise workloads.
