3 TB Near-Line SATA Drive

This 3 TB 3.5-inch hard drive spins at 7200 RPM and connects through a SATA 6 Gb/s interface. It ships new with a hot-swap tray included and is intended for desktop or server storage bays that accept standard 3.5-inch drives.

SATA 6 Gb/s Throughput Limit

The SATA 6 Gb/s link caps sustained transfer rates at the interface maximum, so sequential performance cannot exceed that ceiling. Random I/O is further constrained by the 7200 RPM rotational speed and the mechanical latency inherent to spinning media.

Hot-Swap Tray Installation

The supplied tray lets the drive slide into a compatible hot-swap bay without tools or cable handling. Installation fails when the chassis lacks a matching 3.5-inch hot-swap cage or when the backplane does not support SATA 6 Gb/s signalling.

Questions about this item

Should I pick the 3 TB 3.5-inch model or a smaller capacity for my server bay?

The 3 TB 3.5-inch drive fills a standard hot-swap bay and delivers 3000 GB of storage; choose it when you need maximum capacity in a single slot.

How does the 7200 RPM speed affect real-world throughput on a SATA 600 link?

At 7200 RPM the drive sustains sequential transfers near the SATA 600 ceiling, while random I/O stays consistent for near-line workloads.

What does the Near Line SATA 6 Gb/s interface actually limit in daily use?

The SATA 6 Gb/s link caps peak transfer at 600 MB/s, so burst speeds cannot exceed that ceiling even if the drive mechanics run faster.
