WD Green 1 TB SATA SSD

The Western Digital WDS100T2G0A is a 1 TB internal solid-state drive built for everyday computing in laptops and desktops. It uses a 2.5 inch 7.00 mm form factor and a SATA III interface rated at 600 MBps. SLC caching accelerates write speeds for routine workloads such as web browsing, casual gaming and fast system start-up.

Upgrade from a mechanical hard drive

Replacing a traditional spinning disk with this SSD removes moving parts, delivering shock resistance rated at 1,500G and vibration tolerance of 5.0 gRMS during operation. The drive draws an average 80 mW active and only 30 mW idle, extending battery life in portable systems. MTBF reaches 1.0M hours, so the reliability jump is clear for any aging HDD.

Limits of the SATA III interface

Sequential reads peak at 545 MBps, which is the practical ceiling of the SATA III bus rather than the flash memory itself. Random workloads and sustained writes will settle below this figure once the SLC cache fills. The drive operates from 0 °C to 70 °C and survives storage from -55 °C to 85 °C, making it suitable for standard consumer environments.

Questions about this item

Does the 2.5 inch 7.00mm height drive fit my laptop bay?

The drive uses the standard 2.5 inch form factor with a 7.00mm z-height, matching most laptop and desktop bays that accept 7mm SATA drives.

Which SATA cable and mounting screws do I need, and what step is often missed?

Connect the drive to a SATA III port with a standard SATA data cable and secure it with 2.5 inch mounting screws; the step often missed is enabling AHCI mode in the BIOS before cloning or installing the OS.

How do I monitor the 1.0M hour MTBF health and when should I plan replacement?

Use the free Western Digital SSD Dashboard to track SMART attributes and remaining life; plan replacement when the tool reports critical warnings or the drive reaches its rated endurance limit.
