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.

Questions about this item
Does the WD20EADS arrive as a bare drive or with cables and mounting hardware?
The WD20EADS is supplied as a bare drive only; no SATA data cable, power adapter, screws or mounting brackets are included.
Should I choose the 2TB WD Green model or a higher-capacity version for a desktop storage upgrade?
This listing offers a single 2TB capacity; there is no higher-capacity variant of the WD20EADS to select.
What real-world throughput can I expect from the 3.0Gb/s SATA interface once the drive is installed?
The SATA 3.0Gb/s link caps burst transfers at 3.0Gb/s; sustained read and write speeds will be lower and depend on the system and workload.
