Western Digital HBS3A1924A4M4B1 M.2 240 GB Serial ATA III 3D TLC NAND

The Right Choice for Server Boot Drives
Built on Western Digital 64-layer 3D NAND, the Ultrastar® SA210 SATA SSD is HGST’s first SSD built specifically for enterprise boot and edge applications. The Ultrastar 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 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 SA210 delivers up to 510MB/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 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 SA210 supports selfencryption drive (SED) capability compliant with TCG OPAL 2.01 to protect data from unauthorized access. The SA210 also includes Instant Secure Erase functionality to speed and simplify drive redeployment and retirement.

M.2 and 2.5-inch Form Factor Support
Ultrastar SA210 supports the M.2 2280 form factor, which is becoming much more widely implemented within 1U and blade servers and broadly adopted by motherboard manufacturers. The M.2 means a much smaller physical footprint and is quickly becoming the de-facto SSD-only form factor. Additionally, the Ultrastar SA210 is available in 2.5-inch to serve as a true drop-in replacement for mechanical HDDs. Both form factors are offered across all five capacity points, from the smallest at 120GB to the largest at 1.92TB.
