The HP 300GB SAS 10K Hard Drive is an enterprise-grade SAS hard disk drive designed for HP/HPE ProLiant servers and storage systems. With a 300 GB capacity, 10,000 RPM spindle speed, and Serial Attached SCSI (SAS) interface, this drive delivers fast seek times, high reliability, and steady performance for business-critical workloads such as virtualization, databases, and enterprise storage arrays.
Capacity: 300 GB — suitable for operating systems, transactional data, or RAID arrays.
Interface: SAS (Serial Attached SCSI) — either 6 Gb/s or 12 Gb/s depending on model.
Spindle Speed: 10,000 RPM — faster than standard SATA drives for improved access and throughput.
Form Factor: 2.5″ Small Form Factor (SFF) — ideal for dense server environments.
Hot-Swappable: Yes — can be replaced while the system is running (with supported backplane).
Dual Port (Some Models): Offers redundant paths to the drive for higher availability.
Cache: Around 16 MB–64 MB on many variants for faster read/write operations.
Many part numbers and variants exist (e.g., 785071-B21 for 12G SAS, 652564-B21, 507127-B21, EG0300FBDBR) but they all follow the same core enterprise specification.
Performance
• 10K RPM rotation speed ensures faster seek times and more responsive I/O than 7.2K SAS/HDDs.
• SAS interface delivers higher throughput and better error handling compared to SATA.
Enterprise-Grade Reliability
• Built for 24×7 operation in demanding enterprise environments.
• Hot-swappable in SAS backplane frames reduces downtime.
• Dual-port variants improve redundancy and allow multipath setups for fault tolerance.
Compatibility
• Works with a wide range of HP ProLiant servers (DL, ML, BL, etc.) and storage enclosures.
• Supports hardware RAID controllers and modern SAS backplanes.
