Western Digital has announced that it is sampling a new 32TB hard drive designed for hyperscale data centers, utilizing advanced technologies such as energy-assisted magnetic recording (EAMR) and shingled magnetic recording (SMR). This nearline HDD incorporates features like triple-stage actuators, two-dimensional read heads, and OptiNAND technology, which enhance performance and reliability. David Goeckeler, the CEO of Western Digital, stated that these drives are intended for seamless integration into cloud and enterprise environments while ensuring high reliability. The 32TB drive competes with Seagate's 30TB Exos HDDs, which are based on heat-assisted magnetic recording (HAMR) technology. Western Digital's UltraSMR technology allows for a significant density increase, achieving up to a 20% capacity boost compared to traditional SMR implementations. However, the starting point for this new drive is 2.56TB CMR platters, which indicates that Western Digital still lags behind Seagate's 3TB CMR platters in terms of areal density. The new drive is specifically targeted at enterprise customers who can manage the complexities associated with SMR technology, which is not inherently transparent for random write operations. Overall, this development marks a significant step for Western Digital in the competitive storage market, as it aims to meet the growing demands of data storage in large-scale environments.
