Does my newly purchased TNAS device come equipped with a hard drive?

Only some TNAS devices come equipped with a hard drive, so please select carefully. TNAS devices that already have a hard drive can be used straight after you have completed the initialization steps. If your TNAS device is supplied without a hard drive, you need to purchase one separately. Your TNAS device can only be used after installing and initializing the hard drive. TNAS is a storage device that needs to run for extended periods, so there are very specific requirements for the choice of hard drive. Dedicated NAS hard drives are recommended. Please go to the official TerraMaster website for a list of hard drives compatible with your specific TNAS device.
