The Right Choice for Server Boot Drives

Built on Western Digital 64-layer 3D NAND, the Ultrastar DC SA210 SATA SSD is Western Digital’s first SSD purpose-built for enterprise boot and edge applications. The Ultrastar DC SA210 offers outstanding value and provides the best alternative to enterprise boot HDDs. With capacities as low as 120GB and up to 1.92TB, you can choose the right capacity point for your operating system and logging requirements. End-to-end data protection and LDPC error correction mechanisms provide greater reliability and help support a five-year warranty. Ultrastar DC SA210 has been validated to operate with Windows Server 2012/2016 and various versions of the enterprise Linux operating systems.

A Natural SSD for Edge Computing & Read-intensive Environments

Edge computing is pushing applications, like content delivery, away from centralized data centers and closer to those who are consuming the content. In such environments, data access speed is essential. The Ultrastar DC SA210 delivers up to 510MiB/s sequential read throughput and 64K IOPS random read performance to unleash the full potential of your server grade system and its high-end CPU capabilities. Such applications can also benefit from higher capacity offerings.

The Ultrastar DC SA210 is designed to be cost-optimized and offer sufficient endurance for read-intensive environments. It is architected to minimize the probability of data loss due to unexpected power loss yet still be a cost-effective alternative to traditional enterprise SSDs that rely on costly hold-up capacitors.

To address encryption requirements, the Ultrastar DC SA210 supports self-encryption drive (SED) capability with TCG OPAL 2.01 SSC security protocol support to help protect data from unauthorized access. The DC SA210 also includes Instant Secure Erase functionality to speed and simplify drive redeployment and retirement.

¹ One MB is equal to one million bytes, one GB is equal to one billion bytes and one TB equals 1,000GB (one trillion bytes). Actual user capacity may be less due to operating environment.
² Endurance rating based on DW/D over 5 years
³ Performance will vary by capacity point, or with the changes in useable capacity. Consult product manual for further details. All performance measurements are in full sustained mode and are peak values. Preliminary and subject to change. 1MiB=1,048,576 bytes or 220, 1KiB = 1,024 bytes or 210.
⁴ MTBF and AFR specifications are based on a sample population and are estimated by statistical measurements and acceleration algorithms under typical operating conditions for this drive model. MTBF and AFR ratings do not predict an individual drive’s reliability and do not constitute a warranty.
⁵Warranty, DW/D is the lesser of 5 years from the date of manufacture of the product or expiration of the relevant endurance threshold
⁶ Operating temperature is defined as temperature reported by the drive. Note that drive temperature readings are expected to be higher than ambient temperature when the SSD is placed inside a system.
