WD Blue 2TB (WD20EZBX) PC Desktop Hard Drive – 7200 RPM, 256MB Cache, SATA 6Gb/s (New)

Reliable everyday storage that expands your desktop PC without overspending.

The WD Blue 2TB (WD20EZBX) is a 3.5-inch SATA 6Gb/s internal hard drive built for desktop PCs, home office machines, and all-in-one systems. It combines 7200 RPM performance, a 256MB cache, and SMR recording to give home users, students, and small offices dependable capacity for OS backups, documents, and a starter game or media library.

Why the WD Blue 2TB Is the Practical Choice for Desktop Storage

Most storage problems in a home or office PC are not about speed. They are about running out of space: a boot SSD fills up with photos, downloads, and game installs, and the system slows down as free space disappears. The WD Blue 2TB solves that by adding 2TB of low-cost-per-terabyte capacity, so you can keep your SSD for the operating system and move bulk data to a drive designed for it.

WD Blue drives are built and validated for desktop PCs, industrial PCs, and external enclosures. Western Digital tests them in its Functional Integrity Testing (F.I.T.) Lab for compatibility, and uses NoTouch ramp load technology so the recording head never rests on the disk surface. That reduces wear during the start-stop cycles typical of a computer that is switched on and off every day.

The WD20EZBX uses SMR (shingled magnetic recording), which overlaps data tracks to increase density and lower cost per terabyte. It performs well for everyday files, media storage, and backups. For sustained heavy writes or multi-drive RAID arrays, Western Digital recommends CMR drives such as WD Red Plus instead, so buy the WD20EZBX for single-drive PC storage.

7200 RPM Performance With 256MB Cache

At 7200 RPM, the WD20EZBX reduces seek and load times compared with 5400 RPM drives, which helps when you open large files or load games directly from the hard drive. The 256MB cache buffers frequently used data for smoother transfers.

Easy Upgrade and Data Migration

Western Digital provides Acronis True Image WD Edition as a free download, so you can clone an existing drive to the new WD Blue without reinstalling your operating system. Advanced power management features also help keep energy use and heat low in everyday operation.
