Seagate Cheetah 450GB 15000 RPM SAS Drive
The Seagate Cheetah ST3450856SS-FR is a 3.5-inch enterprise hard drive built for high-speed transactional workloads. Its 15000 RPM spindle and 16MB cache deliver low latency for database and server applications. The SAS 3Gb/s interface provides dual-port reliability for continuous operation. This refurbished unit suits replacement or capacity expansion in compatible storage arrays.
Suits SAS arrays needing 15K performance.
This drive fits servers and arrays with native SAS 3Gb/s backplanes that can utilise 15000 RPM throughput. It is not for systems lacking SAS connectors or controllers. Buyers needing larger capacities or different form factors should consider other options. The 450GB capacity addresses specific legacy volume requirements.
Deciding spec: SAS 3Gb/s interface
The single specification that determines fit is the SAS 3Gb/s interface. Your host bus adapter or backplane must support this exact protocol to recognise and communicate with the drive. Without a compatible SAS connection the drive cannot function. Verify the interface before purchase.

Questions about this item
Should I choose the 450GB 15000 RPM version or a larger capacity model?
The 450GB capacity at 15000 RPM targets high transaction rates rather than bulk storage; pick it when random I/O speed matters more than total space.
What does the 15000 RPM speed deliver inside a server?
15000 RPM cuts average rotational latency to about 2 ms, giving faster random read/write response for database or transaction workloads.
How does the SAS 3Gb/s link limit real-world throughput?
The SAS 3Gb/s interface sets a 3 Gbit/s signalling rate per port, so sustained transfers cannot exceed the link's raw bandwidth ceiling.
