DELL WD1003FBYX 1TB 7.2K SATA 3.5in internal hard drive

Capacity and Interface

This Dell desktop internal hard drive provides one terabyte of storage on a standard SATA connection. It suits system builders and upgraders who need bulk capacity for documents, media or backups in a 3.5-inch bay. The 7.2K rotational speed delivers consistent throughput for everyday workloads.

SATA Throughput Limit

The SATA interface caps maximum transfer rates at six gigabits per second, so sustained reads and writes cannot exceed that ceiling. Random-access performance is bounded by mechanical latency inherent to spinning media. Workloads requiring very low latency or high queue-depth throughput will hit this interface and physics limit.

Build and Mounting

The drive uses a conventional 3.5-inch form factor with standard SATA data and power connectors, fitting typical desktop drive cages and backplanes. No special brackets or adapters are required for installation. Mechanical operation produces audible seek noise and vibration that may be noticeable in quiet environments.
