Ultrastar DC HC500 Series
High Capacity for Massive Data and Lower Total Cost of Ownership

Driving Up Capacity and Driving Down TCO for Cloud and Hyperscale Data Centers
The breadth and depth of Big Data is driving the universal need for higher capacities across a broad spectrum of applications and workloads. Laying the foundation for a worry-free data center, Western Digital delivers the capacity to conquer the data explosion with the Ultrastar DC HC500 series of hard drives. Built using HelioSeal technology, the industry’s only fifth-generation helium platform, the DC HC500 series is designed for public and private cloud environments, where storage density, Watts/TB and $/TB are critical for creating the most cost-efficient infrastructure. HelioSeal technology is key to achieving higher drive capacities, greater reliability ratings and extreme power efficiency. The result is a lower Total Cost of Ownership (TCO) for our cloud and enterprise customers.

Beyond Air. Helium Takes You Higher.
Responding to the complex needs of the modern data center, Western Digital has developed HelioSeal technology, a foundational building block for high-capacity hard disk drives (HDDs). This innovative technology hermetically seals the HDD and replaces the air inside with helium, which is one-seventh the density of air. The less dense atmosphere resets the boundaries and challenges of conventional high-capacity HDDs, allowing for dramatic increases in efficiency, reliability and value.

Higher Capacity
12TB CMR HDD, drop-in ready for capacity-optimized workloads

Lower Power
52% lower idle Watts/TB than 8TB Ultrastar air-filled drives

More Reliable
Unbeaten MTBF rating for an HDD at 2.5M hours

Medium Capacity for High Access-Density Requirements

Delivering Economics and Access Speed to Data Center Applications and Workloads

As the industry evolves to develop purpose-built solutions for growing data storage requirements, IT managers continue to rely on mid-range capacity drives that are economical to acquire, yet deliver quick and reliable data access for traditional data center applications. Designed to handle workloads up to 550TB per year, the Ultrastar DC HC300 series is a proven air-platform design that delivers up to the industry leading 10TB of capacity to help address the economic and access-density requirements of many data center workloads. Ideal for storage and server applications, as well as distributed and scalable computing (including block and file storage architectures), the Ultrastar DC HC300 series provides fast 7,200 RPM spindle speeds and is offered in either 6Gb/s SATA or 12Gb/s SAS interface with advanced format 512e3 sector size.

Solves Access Density Challenges

Economical Capacity

4TB, 6TB, 8TB, and 10TB models for lower acquisition cost.

High Performance

Fast data access with 7200 RPM speed, transferring up to 255 MB/s.

Drop-In Ready

SAS and SATA options support traditional servers and storage.

Samsung’s PCIe Gen 4-enabled PM1733 SSD will have double the throughput capabilities of current Gen 3 SSDs, giving it the highest performance of any SSD on the market today. The two NVMe SSD series come in two form factors, 2.5-inch and HHHL, with capacities ranging from 0.8TB to 30.72TB to suit the diverse needs of OEMs worldwide. The drives also ensure endurance of one or three drive writes per day (DWPD) over a five-year period.

For the Demands of Big Business Designed specifically with medium or large scale business customers in mind, WD Red™ Pro drives are available for up to 24-bay NAS systems. Engineered to handle high-intensity workloads1 in 24x7 environments, WD Red™ Pro is ideal for archiving and sharing, as well as RAID array rebuilding on extended operating systems such as ZFS or other file systems. These drives add value to your business by enabling your employees to quickly share their files and back-up folders reliably in your NAS solution. Exclusive NASware™ 3.0 Technology Our exclusive advanced firmware technology, NASware™ 3.0, enables seamless integration, robust data protection and optimal performance for NAS systems operating under heavy demand. Built into every WD Red™ Pro hard drive, NASware 3.0’s advanced technology improves storage performance by increasing compatibility, integration, upgradeability, and reliability. Built for Optimum NAS Compatibility WD Red™ Pro drives with NASware™ technology takes the guesswork out of selecting a drive. Optimized for NAS systems, our unique algorithm balances performance and reliability in NAS and RAID environments. Simply put, a WD Red™ Pro drive is one of the most compatible drives available for NAS enclosures. But don’t take our word for it. WD Red™ Pro drives are a reflection of extensive NAS partner technology engagement and compatibility-testing. Larger NAS Bay Shock Protection WD Red™ Pro drives are equipped with a multi-axis shock sensor that automatically detects subtle shock events and dynamic fly height technology which adjusts each read-write function to compensate and protect the data. This combination of technology further protects the drives in larger 24-bay NAS environments and helps increase hard drive reliability. 3D Active Balance Plus Our enhanced dual-plane balance control technology significantly improves the overall drive performance and reliability. Hard drives that are not properly balanced may cause excessive vibration and noise in a multi-drive system, reduce the hard drive life span, and degrade the performance over time. Error Recovery Prevention Built specifically for RAID and NAS environments, WD Red™ Pro drives come equipped with error recovery controls as part of NASware™ 3.0 technology to help reduce drive fallout in RAID applications. Extended Drive Testing A NAS environment that has up to 24 bays is very demanding on a hard drive with added vibration and heat. This is why every WD Red™ Pro drive is shipped with extended thermal cycle burn-in testing to help ensure each drive is tested for extended reliable operation. Desktop drives vs. WD Red™ Pro Do right by your NAS and choose the drive purpose-built for NAS with an array of features to help preserve your data and maintain optimum performance. Take the following into consideration when choosing a hard drive for your NAS:

PM983, M.2, 1.92 TB

12TB, 3.5", SATA 6 Gb/s, 7200 rpm

10TB, SAS, 3.5", 256MB, Base (SE)

PCIe Gen4 x4/dual port x2, 1.92 TB, 2.5", 7000 MB/s

18TB, 7200rpm, SATA, 272MB/s
