Seagate 2.5 inch SAS hard drive silver metal enclosure

Seagate

Seagate ST9300653SS 9SW066 300GB 15KRPM 2.5" SAS 64MB internal hard drive

SKU CH-16YV-JDPHG

300 GB, 15 000 RPM SAS drive with 64 MB cache for high-speed enterprise storage

  • 15,000 RPM for fast transaction processing
  • 300 GB capacity for critical datasets
  • 64 MB cache to accelerate read operations
  • 5" SAS 6 Gb/s interface for server compatibility
  • Zero-hour condition confirms factory-new state

Enterprise 2.5" SAS drive

The Seagate SAVVIO 15K.3 ST9300653SS is a 300GB 15000RPM internal hard drive built for enterprise servers and storage arrays that demand consistent transactional throughput. Its 6Gb/s SAS interface and 64MB cache suit database, virtualization and high-performance computing workloads where low latency matters more than raw capacity.

2.5-inch SAS form factor

The 2.5-inch SAS connector fits standard hot-swap drive bays and backplanes, allowing tool-less replacement in rackmount chassis without cable routing. Zero reported power-on hours confirm the drive ships in factory-new condition, reducing early-life failure risk for mission-critical deployments.

15K RPM thermal profile

At 15000RPM the spindle generates more heat and audible seek noise than slower nearline drives, so adequate chassis airflow is required for sustained operation. The 6Gb/s SAS link negotiates down to 3Gb/s on older controllers without configuration changes, preserving compatibility across generations.

Questions about this item

What real-world throughput does the 6Gb/s SAS interface on the ST9300653SS deliver?

The 6Gb/s SAS interface provides a maximum theoretical bandwidth of 6Gb/s; actual sustained transfer rates depend on the 15000RPM mechanics and 64MB cache.

What physical space and connector does the 2.5-inch SAS drive require?

The ST9300653SS fits a standard 2.5-inch drive bay and uses a SAS 6Gb/s connector; it weighs 1.0 pound.

How is the Seagate SAVVIO 15K.3 installed, and what step is often missed?

Mount the 2.5-inch drive in a compatible bay, attach the SAS data and power cables, then configure the drive in the RAID or HBA BIOS so the 300GB volume appears to the OS.
