Know before you buy
While this drive is physically compatible with most desktop cases that support 3.5-inch drives, it is specifically engineered for 24/7 enterprise data center workloads. It may run louder and warmer than standard consumer-grade hard drives, so ensure your PC case has adequate airflow.
The Exos X20 features built-in digital environmental sensors that monitor drive conditions. You can track this data using standard S.M.A.R.T. monitoring tools compatible with SATA interfaces.
PowerBalance technology helps optimize the power consumption per terabyte. This is particularly useful in large-scale server environments where minimizing energy usage across dozens or hundreds of drives significantly reduces operational costs.
Yes, this is a bare drive, meaning it does not include mounting screws, SATA cables, or software. You will need a standard SATA data cable, a SATA power connector from your power supply, and a 3.5-inch drive bay to complete the installation.
The 7200 RPM rotational speed combined with the 256MB cache ensures consistent data transfer rates and quick access times for large files. It strikes a balance between high-capacity storage density and the sustained performance required for cloud and data center applications.
