The Lockerstor 4 (AS6604T) is a cost-effective high capacity NAS designed for enterprise environments. The Lockerstor 4 is flexible, supporting online capacity expansion and replacement. Online capacity expansion enables you to replace hard drives inside the NAS without downtime. If your budget and/or storage requirements are small, the Lockerstor 4 enables your NAS to grow alongside your needs by first purchasing smaller drives and then add more drives as you need. Additional drives can be purchased as your storage requirements grow and all drives can be fully replaced while continuing to use your NAS. Combining this with ASUSTOR’s MyArchive cold storage technology enables you to store a virtually unlimited amount of information.
