Western Digital has provided details on its new 3.5-inch HDDs based on HAMR (Heat-Assisted Magnetic Recording) technology. These hard drives will use 14 platters to achieve a storage capacity of 140 TB and beyond.

HAMR Technology

HAMR technology is a solution to increase the storage density of hard drives. It heats a small area of the disk during data writing, allowing more data to be stored in a smaller space. This approach makes it possible to overcome the limitations of conventional magnetic recording technologies.

Implications

The increase in HDD capacity is crucial for applications that require large amounts of storage, such as data centers, high-resolution video storage, and data backup. For those evaluating on-premise deployments, there are trade-offs between storage density and other factors such as energy consumption and TCO, which AI-RADAR analyzes in detail on /llm-onpremise.
