Even though SSDs dominate the consumer market, Western Digital has shared a roadmap that shows the company is still pushing hard on traditional hard drives. According to WD, its next-generation HDDs could deliver speeds up to four times faster than current models.
These upcoming drives will rely on two key technologies, called High Bandwidth Drive and Dual Pivot. The goal is not only to increase storage capacity, but also to greatly boost performance to levels never seen before on mechanical hard drives.
New Technologies Aim to Boost HDD Performance
The first major innovation is High Bandwidth Drive technology. This system uses independent read and write heads on each disk surface, allowing multiple operations to happen at the same time. Current prototypes have already managed to double bandwidth, and Western Digital’s long-term goal is to reach a 4x increase in transfer speeds, without raising power usage or requiring software changes.
The second technology, Dual Pivot, adds a second independent pivot for the actuators. When combined with High Bandwidth Drive, Western Digital expects a total 8x increase in bandwidth. This could push future HDDs to transfer speeds of up to 2 GB/s, far beyond the limits of today’s SATA interface. Reaching these speeds would also require updates to server connection infrastructure to fully take advantage of the performance.
With the rise of technologies like HAMR (Heat-Assisted Magnetic Recording), hard drive capacities continue to grow. However, capacity alone is not enough if data access remains slow.
Western Digital believes that IOPS per terabyte will become a key factor going forward. Having 100 TB of storage is not useful if moving that data takes too long. Thanks to these improvements, future HDDs could reach speeds close to entry-level SSDs, making them far more competitive in certain use cases.
