Provide 20 TB of enterprise SATA capacity for storage systems that require large volumes of online data on 3.5-inch rotating media. The ACCORTEC ACCHD357220TN connects through a SATA 6 Gb/s interface and fits environments built around SATA drive bays, including server-attached storage, disk shelves, and capacity-oriented storage arrays. At 7,200 RPM, the drive is suited to workloads where high capacity and conventional hard-drive economics take priority over flash storage latency. Its 256 MB buffer supports drive-level data handling, while the SATA interface provides a familiar connection type for systems with available SATA storage channels. The 3.5-inch disk format targets full-size internal drive bays rather than compact notebook or small-form-factor bays. This configuration combines 20 TB capacity, a 7,200 RPM spindle, and a 256 MB buffer in one enterprise hard-drive format. Review the target system's supported drive interface, physical bay format, controller capacity support, and storage architecture before installation. It is a focused option for expanding bulk capacity where a 3.5-inch SATA hard drive is required.
