Western Digital Black WD4001FAEX 4TB 7.2K 3.5" SATA Hard Drive - Brand New
Sophisticated performance enhancing features deliver the speed you need for demanding applications like photo and video editing and Internet gaming.
High performance, high capacity, high reliability, and cutting-edge technology make up WD Black, the ideal drive for those who demand only the best.
WD Black carries the highest available warranty protection on the market, a 5-year limited warranty.
Twice the processing power to maximize performance.
WD’s dynamic caching algorithm improves performance in real time by optimizing cache allocation between reads and writes. For example, if there’s an overwhelming percentage of read traffic as opposed to write traffic, the drive automatically allocates more cache for read data, which reduces congestion and improves overall drive performance.
Rock-solid mechanical architecture
Enhanced reliability features help protect the drive and the data stored on it.
NoTouch™ ramp load technology
The recording head never touches the disk media ensuring significantly less wear to the recording head and media as well as better drive protection in transit.
The motor shaft is secured at both ends to reduce system-induced vibration and stabilize platters for accurate tracking during read and write operations which enables consistently higher performance. (4 TB, 3 TB and 2 TB models only)
