Western Digital WD20EADS 2TB 32MB Cache SATA 3.0Gb/s 3.5" internal hard drive

What this drive is and who it suits

The Western Digital WD20EADS is a 2TB 3.5-inch desktop hard drive with a SATA 3.0Gb/s interface and 32MB cache. It belongs to the WD Green series and uses IntelliSeek, NoTouch and IntelliPower technologies to reduce power consumption by up to 40 percent. The drive is sold new as a bare unit without cables or brackets. It is intended for bulk storage such as media libraries, documents and system backups in a desktop PC.

What to verify before ordering

Confirm that your motherboard or controller provides a free SATA port and that your power supply has an available SATA power connector. The drive requires a standard 3.5-inch drive bay and mounting screws. Because it is a bare drive, no formatting or partitioning has been performed; you will need to initialise it in your operating system before use. Ensure your system BIOS or UEFI recognises drives of this capacity.

Thermals noise and power draw

The Green series technologies aim to keep the drive cool and quiet during typical desktop workloads. Reduced power consumption means less heat output compared to standard desktop drives of the same era. Acoustic levels remain low for background storage tasks. The drive has been erased to DoD 5220.22 M standard and tested good; up to 25 bad sectors may be present.
