Enterprise 2.5-inch SAS drive
The Seagate ST2000NX0263 is a 2TB 2.5-inch hard drive spinning at 7200 RPM with a SAS 12Gb/s interface and 128MB cache. It targets enterprise storage arrays and servers that need high-capacity nearline storage in a compact 15mm z-height form factor.
SAS 12Gb/s interface limits
The SAS 12Gb/s interface provides a 12Gb/s transfer rate, but sustained throughput is bounded by the 7200 RPM rotational speed and 4.16ms average latency. Sequential performance gains of 18% over the previous generation apply only to comparable nearline workloads, not random I/O patterns.
Installation and common issues
The 2.5-inch form factor with 15mm height fits standard enterprise drive bays and backplanes using SAS connectors. Installation fails when the backplane or controller does not support 12Gb/s SAS signalling, or when the 15mm z-height exceeds the bay clearance in some dense 2.5-inch chassis.

Spørgsmål om denne vare
Should I choose the 2TB 2.5-inch SAS model or a larger capacity for my storage array?
The ST2000NX0263 provides 2TB in a 15mm 2.5-inch form factor, designed for high-density enterprise storage where space is constrained.
What does the 7200 RPM speed mean for actual throughput in my server?
The 7200 RPM spindle with 4.16ms average latency delivers 18% better sequential performance over the previous generation, suited for nearline workloads.
How does the SAS 12Gb/s interface limit real-world transfer rates?
The SAS 12Gb/s interface caps the maximum burst transfer rate at 12Gb/s, while sustained throughput depends on the 7200 RPM mechanics and 128MB cache.
