Room for demanding storage workloads
With 18TB available, this drive can hold extensive files and data on a single hard drive. That makes it a practical choice for server and workstation storage where capacity matters.
The 550TB-per-year workload rate limit gives you a clear guide to its intended operating workload. Consider your system’s annual data transfers when choosing a drive for a busy environment.
