  • 900 GB capacity stores large datasets
  • 10000 RPM spindle delivers fast data access

Dell Savvio 900GB 10K SAS drive

The Dell Savvio 10K.5 ST9900805SS is a 900GB 2.5in SAS hard drive spinning at 10000RPM with a 64MB cache. It targets enterprise servers and storage arrays that need high IOPS in a small form factor. The drives ship new with zero hours and include a PowerEdge caddy tray for direct installation.

Tool-less caddy install in PowerEdge bays

Each drive arrives mounted in a Dell PowerEdge 2.5in caddy that slides into the hot-swap bay of supported servers. No screws or tools are required; the tray locks with the chassis lever. The only common issue is attempting to use the drive in a system that lacks a 6Gbps SAS backplane or RAID controller.

Steady 10000RPM throughput under load

The 10000RPM spindle maintains consistent rotational speed during sustained workloads, avoiding the latency spikes seen in variable-speed drives. The 64MB buffer absorbs write bursts while the 6Gbps SAS interface keeps the pipe full during long sequential transfers.
