Buffalo 20TB Replacement Drive for TeraStation 51210RH

The Buffalo OP-HD20.0H2U-5Y is a twenty-terabyte hard drive that serves as a direct replacement or capacity upgrade for the TeraStation 51210RH network storage system. Built for the demands of continuous operation, it fits into a standard three-point-five-inch bay and connects at six hundred megabytes per second, so large datasets open quickly and backups finish on schedule.

This drive arrives pre-configured for hot-swap use, which means an administrator can slide it into a compatible TeraStation while the array is running and restore full redundancy without shutting anything down. The simple tray design and precise dimensions of six point eight by four point two by one point one inches match the original equipment, keeping airflow and cable routing exactly as Buffalo intended.

Creative studios archiving high-resolution media, offices consolidating shared documents, and managed service providers maintaining client backups will appreciate the roomy capacity. With twenty terabytes available, a single bay can store tens of millions of project files or months of surveillance footage, reducing the need for frequent drive additions.

Buffalo supports the OP-HD20.0H2U-5Y with a five-year warranty, giving IT teams confidence that the drive will stand up to long duty cycles in temperature-controlled racks or small business server closets alike. If a drive ever needs replacement, the same hot-swap design shortens recovery time and keeps the array online.
