3.5-inch 300GB 15K RPM SAS Hard Drive, EMC 005049273-RFB

3.5-inch 300GB 15K RPM SAS Hard Drive, EMC 005049273-RFB is a high-performance enterprise-class SAS hard disk designed for use in servers and storage arrays. With a 3.5-inch form factor, 300 GB capacity and 15,000 revolutions per minute spindle speed, this drive targets workloads that require low latency and sustained random I/O throughput. It is intended for block-level storage in database systems, virtualized environments and transactional applications where predictable performance is important.

Advantages

This EMC 3.5-inch SAS drive delivers fast rotational speed and enterprise-grade reliability characteristics suited to data center use. The 15K RPM spindle reduces average access times compared with lower-speed drives, improving transaction response and mixed I/O performance. The drive is built for continuous operation in multi-drive arrays and supports typical enterprise features such as robust error handling and consistent performance under sustained load.

Suitable for

• Database servers requiring low latency random I/O
• Virtualization hosts and hyper-converged systems
• Transactional applications and OLTP workloads
• Enterprise storage arrays and RAID configurations
• Read/write intensive file servers where spindle performance matters

When it may not be suitable

This 15K RPM SAS HDD is not the best choice for cold storage or archival purposes where high capacity and low cost per TB are the priority. It also may be less appropriate in environments optimized for maximum sequential throughput where large-capacity, lower-RPM drives or SSDs provide better cost-efficiency. Systems that require NVMe or SATA SSD-level latency and IOPS may require solid-state storage instead.

Key specifications

• Form factor: 3.5-inch
• Storage capacity: 300 GB
• Interface: SAS (serial attached SCSI)
• Rotational speed: 15,000 RPM
• Optimized for block storage and enterprise workloads
• Designed for continuous operation in server and array environments

How to use

Install the drive into a compatible SAS-capable server or storage enclosure following the host vendor's service manual. Ensure the drive is mounted in an appropriate 3.5-inch bay or adapter and that SAS cabling and backplane connections meet the enclosure specifications. Configure the drive within the operating system or storage controller, and include it in RAID or volume groups according to your redundancy and performance requirements. Monitor SMART or vendor-supplied health metrics regularly and follow standard maintenance and firmware update procedures recommended by the system manufacturer.

What to consider before purchase

• Verify host/server compatibility with 3.5-inch SAS drives and required interface version
• Assess whether 300 GB capacity and 15K RPM performance meet your workload requirements
• Plan RAID level, redundancy and spares for enterprise availability
• Check thermal, power and vibration limits in your enclosure

Usage recommendations

Deploy this EMC 15K SAS drive in RAID arrays for transactional databases and virtual machine storage tiers where consistent low-latency performance is required; combine with monitoring and regular firmware updates to maintain reliability.
