Add 24 TB of enterprise hard-drive capacity to SATA storage nodes that require a TAA-compliant configuration. Western Digital 1ES2126 combines a SATA host interface, 512e sector emulation, helium-filled disk technology, and self-encrypting-drive functionality. It addresses capacity expansion where the server, storage enclosure, or replacement bay accepts a 3.5-inch SATA hard drive and where data-at-rest encryption is part of the storage design. Use its SATA connection for direct-attached bays and SATA-capable storage shelves rather than platforms that require a SAS interface. The 512e format exposes 512-byte logical sectors, helping maintain compatibility with systems and software built around 512-byte sector addressing. Validate host, enclosure, and operating-system support for the 3.5-inch form factor, SATA connection, and encryption-management workflow before installation. This configuration combines high-capacity 24 TB storage with a helium-filled enterprise HDD platform, TAA compliance, and self-encrypting-drive capability. That combination suits capacity-focused storage tiers where conventional SATA infrastructure is already present but encryption and compatibility requirements still apply. The 7,200 RPM spindle speed supports enterprise hard-drive operation for storage pools, backup targets, and scale-out server nodes that need large local or enclosure-based capacity.
