Provide 1,020 TB of installed enterprise hard-drive capacity in a single 4U storage enclosure. Western Digital 1ES1802 is configured as the SE4U102-102 platform, combining 102 HC330 SAS hard drives for dense nearline storage where rack space and usable capacity are primary design constraints. The enclosure format concentrates a large drive population into a footprint that can serve centralized capacity tiers, scale-out storage nodes, or archive-oriented environments. The installed drives use a SAS interface, giving the configuration a storage connection suited to enterprise server and storage architectures that support SAS-attached disk shelves. Each drive is specified with 512e sector emulation, presenting 512-byte logical sectors while using advanced-format media internally. This format helps maintain compatibility with operating systems, RAID controllers, and storage software expecting conventional 512-byte logical-sector behavior. TCG self-encrypting drive capability distinguishes this configuration from an equivalent unencrypted disk population. Encryption is performed by the drives and can support data-at-rest protection policies when paired with compatible management and key-handling infrastructure. The SE4U102-102 configuration also differs through its fixed 102-drive population and 1,020 TB installed capacity, rather than requiring capacity to be calculated from separately selected drives. Specify the platform where a dense, preconfigured SAS hard-drive enclosure is required.
