3 hard drives 22 TB available from Western Digital

We presented them to you last May, Western Digital’s CMR (Conventional Magnetic Recording) hard drives with a capacity of 22 TB are now on the market. The three available models Red Pro, Purple Pro and Gold Pro are designed for servers and storage arrays (NAS and others). To deliver this capability, they are helium sealed (HelioSeal) to reduce platter vibration and improve reliability, and leverage ePMR (electrical Perpendicular Magnetic Recording) technologies to reduce power consumption and OptiNAND to increase capacity useful. This flash memory with a UFS interface stores metadata related to files to optimize the movement of read and write heads. This metadata, previously kept on the platters, also frees up space on the hard disks. In addition, OptiNAND is compatible with ArmorCache technology, for data security, which boosts performance and write cache protection.

Note that each version of these hard drives is aimed at a particular segment. Thus, the Purple Pro model is intended for video surveillance and supports up to 64 video streams. It incorporates an MTBF of up to 2.5 million hours as well as AllFrame AI technology which makes it possible to analyze and reduce the number of frames lost during video recordings. This model is available in capacities ranging from 8 to 22 TB. The Red Pro variant is intended for NAS with a storage capacity ranging from 2 to 22 TB. Finally, the Gold Pro model is intended for data centers, SMEs and other IT companies. , its capacity ranges from 1 TB to 22 TB.

Hard drives still essential

Western Digital’s senior vice president of product management and marketing, Ravi Pendekanti, said of the release of these models, “We are excited to reach this milestone because hard drives are complex and sophisticated. They play an essential role in storing, protecting, capturing and analyzing data”.
