The Dell 300GB 15K RPM SAS 2.5in Hard Drive and similar models are enterprise-grade internal hard disk drives (HDDs) designed for high-performance server storage and critical workloads. With a 300 GB capacity, ultra-fast 15 000 RPM rotational speed, and Serial Attached SCSI (SAS) interface, these drives provide high I/O throughput, low latency, and robust reliability — ideal for transactional databases, virtualization, RAID arrays, and operating system volumes in Dell PowerEdge and other enterprise server systems.
300 GB Storage Capacity — compact but suitable for high-performance data segments and OS/DB volumes.
15 000 RPM Rotational Speed — very low latency and high IOPS for demanding workloads.
SAS Interface (6 Gbps or 12 Gbps) — enterprise-class data transfer with robust signalling and error correction.
2.5-inch Small Form Factor (SFF) — space-efficient drive suitable for high-density server chassis.
Hot-Swap/Hot-Plug Support — allows replacement or maintenance without powering down (when supported by system backplane).
Designed for 24/7 Operations — suitable for continuous enterprise workloads.
Compatible with Many Dell PowerEdge Servers — e.g., R320, R420, R520, R620, R720, R720xd, R740XD and similar models with 2.5″ SAS bays.
Often Works with SAS RAID Controllers — PERC and SAS HBAs in server environments.
