Enterprise server storage

The Seagate Cheetah ST3450856SS is a 450GB 3.5 inch internal hard drive built for enterprise servers. It spins at 15000 RPM with a 16MB cache and connects via a SAS 3Gb/s interface. The bare drive arrives in low-profile 1.0 inch height packaging.

Suited for high-IOPS workloads

This drive suits administrators who need low average latency for transaction-heavy server workloads. It is not for systems that lack a SAS host adapter, builds that require a current manufacturer warranty, or users who need a consumer-grade desktop drive.

SAS 3Gb/s interface decides fit

The single specification that determines compatibility is the SAS 3Gb/s interface. The server or controller must support this exact connection standard for the drive to function.

Spørgsmål om denne vare

How does the 15000 RPM spindle speed affect real-world access times in a server?

The 15000 RPM rotation yields an average latency of 2.0 ms, so random read and write requests complete faster than on slower-spinning drives.

What does the SAS 3Gb/s interface limit in practice?

The SAS 3Gb/s link caps the maximum burst transfer rate at 3 Gb/s, so sustained throughput cannot exceed that ceiling regardless of the backplane.

Will this 3.5 inch low-profile drive fit in a standard 3.5 inch drive bay?

Yes, the 3.5 inch form factor with a 1.0 inch height matches the standard low-profile 3.5 inch bay dimensions used in most servers.
