About this product
This is a used Western Digital WD Blue WD6400AAKS 640 GB 3.5-inch internal hard drive. It connects via a SATA II interface and operates at a rotational speed of 7200 RPM, backed by a 16 MB cache. Compatible with PCs, this drive is designed for desktop machines and provides a moderate storage capacity within the WD Blue product line.
Our take
The Western Digital WD Blue 640GB drive, while used, offers a decent blend of capacity and speed for a budget desktop build or an older system upgrade. The 7200 RPM ensures responsive performance for an HDD, and 640GB is generally enough for an operating system and a good selection of programs. The SATA II interface is a bit older, which means it might not offer the full bandwidth of SATA III, but for mechanical drives, the real-world difference is often negligible. It's a solid, practical choice if you're mindful of its used status.
