The Seagate One Touch Hub (10 TB) uses a single 3.5" hard drive with USB 3.0 ports, but there is no specific information on whether it is a CMR or SMR hard drive or what speed (rpm) it has. The available information from the search results and common Seagate product lines do not provide any clear information for this model.
In general, Seagate external hard drives with 10 TB are often CMR (Conventional Magnetic Recording), as these provide better performance and reliability, especially with larger capacities. The typical speed for 3.5" hard drives of this capacity is usually 7,200 rpm, but can also be 5,400 rpm, depending on the model and intended use.
As there is no reliable, model-specific information available, I recommend contacting Digitec or Seagate directly to confirm the exact recording technology (CMR or SMR) and the speed of the installed hard drive.
