Enterprise SAS Drive for Mission-Critical Servers

The Seagate Savvio 10K.5 ST9900805SS is a 2.5-inch internal hard drive built for enterprise servers and external storage arrays. It connects via a SAS 6Gb/s interface and spins at 10000 RPM with a 64MB cache. This new bare drive is designed for workloads that demand consistent throughput and low latency in a 15mm height form factor. It is not suitable for desktop PCs or laptops lacking a SAS controller and backplane.

900GB Capacity with 10000 RPM Performance

The 900GB capacity provides substantial space for operating systems, databases and transaction logs in a single spindle. At 10000 RPM the drive delivers an average latency of 3ms, giving quick access to frequently used data. The 64MB cache helps absorb burst writes and read-ahead patterns. Workloads requiring higher IOPS or capacities beyond 900GB will need additional drives or solid-state alternatives.

DoD-Compliant Erasure and One-Year Seller Warranty

Each drive has been erased to the DoD 5220.22-M standard and tested to a minimum 90% health threshold. The manufacturer has ended sale and warranty coverage, so the seller provides a one-year warranty from purchase date. Drives ship unformatted, unpartitioned and unallocated, requiring setup in the host RAID controller or operating system. Cosmetic markings or label variations may be present.

Questions about this item

Will the 2.5" 15mm SAS 6Gb/s drive fit in a server bay that currently holds 2.5" 15mm SAS 3Gb/s drives?

Yes, the SAS 6Gb/s interface is backwards compatible with 3Gb/s controllers, and the 15mm height matches the existing bay spacing.

How can I confirm the 10000 RPM drive is performing correctly after installation?

Run a SMART self-test and verify the reported RPM is 10000 and the average latency reads 3ms.

Does the bare drive include a SAS cable or mounting bracket, or must I supply them?

The bare drive ships without cables or brackets; you must provide a SAS data cable, power connector and any required 2.5" mounting hardware.
