Universal HDD

The WD Blue WD40EZAX hard drive with CMR magnetic recording technology provides 4 TB of memory, making it an excellent budget solution for creating a simple video surveillance system or assembling a home computer. It copes with processing multiple data streams from cameras in HD/FHD resolution and allows you to save a month's video archive (for 1-2 devices). The 3.5" form factor is suitable for any computer cases, network storage and video recorders. The model is characterized by low power consumption, minimal noise level and is equipped with vibration suppression mechanisms and rotation control sensors, which allows you to use it in RAID arrays and NAS with high savings. In addition, the drive is great for storing multimedia and performing standard tasks on a home or office PC.

Quality assurance

WD Blue WD40EZAX with 4 TB and CMR technology provides data transfer rates of up to 180 MB/s. The use of caching technology minimizes the risk of queue overflow and data loss. The cache size for data processing is 256 MB. NoTouch Ramp Load technology is also used, which reduces wear on the plates and prevents their damage during operation. However, with all the advantages, a two-year limited warranty may seem insufficient. Among the additional benefits, Acronis True Image WD Edition software stands out, which allows you to easily create backup copies of files, partitions, or the entire disk for quick recovery or transfer of data.
