UltraSMR technology is a cutting-edge storage technology developed by Western Digital to meet the growing demands for higher capacity in hard disk drives (HDDs). This post from Partition Magic will provide more details for readers who are interested in this technology.
Overview of UltraSMR Technology
UltraSMR (Ultra Shingled Magnetic Recording) is an advanced technology introduced by Western Digital to significantly increase the storage capacity of hard disk drives (HDDs). At its core, UltraSMR builds on the principles of Shingled Magnetic Recording (SMR), which has been a pivotal technology in increasing HDD capacity over the past decade.
Traditional SMR involves partially overlapping the data tracks on the disk, similar to the shingles on a roof, which allows for more data tracks on the same surface area, thereby increasing storage capacity. However, this overlapping can complicate the writing process, as writing to one track may require rewriting adjacent tracks, leading to potential performance trade-offs.
UltraSMR overcomes these challenges by integrating several advanced technologies:
- OptiNAND Technology: This involves integrating NAND flash memory into the hard disk, reducing the need to rewrite adjacent tracks. This makes the writing process smoother and faster, mitigating the performance drawbacks often associated with traditional SMRs. This significantly improves the performance and data integrity of the hard disk.
- Energy-Assisted PMR (ePMR): Energy-assisted recording technologies, such as ePMR, use an external energy source to assist the writing process, allowing for more precise and stable recording of data on the disk. This increases the track density, enabling UltraSMR drives to store more data without compromising reliability.
- Advanced Error Correction Algorithms: UltraSMR employs sophisticated error correction algorithms that enhance the reliability and integrity of the stored data. These algorithms ensure that even with the higher density and overlapping tracks, the data can be read accurately and efficiently, reducing the risk of data corruption.

Advantages of UltraSMR
The primary advantage of UltraSMR technology is its ability to significantly increase the storage capacity of HDDs. Western Digital’s implementation of UltraSMR has led to the development of the 26TB Ultrastar DC HC670 UltraSMR HDD, which offers an 18% increase in storage capacity compared to previous models.
This drive is specifically designed for hyperscale cloud service providers, who require large-scale storage solutions to manage their vast amounts of data efficiently.
Another key benefit is the improved total cost of ownership (TCO). By providing higher storage density, UltraSMR reduces the physical footprint and energy consumption per terabyte of data stored.
This is particularly important for data centers, where space and power efficiency are critical factors. The integration of OptiNAND technology also enhances the drive’s performance, making it a cost-effective solution for handling large volumes of sequential write workloads.
Applications of UltraSMR
UltraSMR technology is particularly well-suited for environments that require high-capacity, cost-effective storage solutions. These include:
- Hyperscale Data Centers: With the exponential growth of data generated by cloud services, social media, and big data applications, hyperscale data centers need to maximize their storage density. UltraSMR provides the necessary capacity and efficiency to meet these demands.
- Bulk Storage: Applications that involve storing large volumes of data, such as online backups, archives, and video surveillance, benefit from the increased capacity and reliability of UltraSMR drives.
- Big Data and Analytics: The ability to store and quickly access vast amounts of data is crucial for big data applications. UltraSMR drives support these needs by offering high capacity and enhanced data integrity.
The development and deployment of UltraSMR technology represent a significant milestone in the evolution of data storage solutions. As data generation continues to accelerate, the need for higher capacity and more efficient storage solutions will only grow. Western Digital’s UltraSMR technology is poised to play a crucial role in meeting these future demands.
