Lenovo 70BA9004NA PX2-300D Diskless Network Storage

The Lenovo PX2-300D is a two-bay diskless network-attached storage device designed to give homes and small businesses a central location for file backup, sharing, and media streaming. Because it ships without drives, you select and install your own 3.5" SATA hard drives—a setup that keeps the initial purchase price low and lets you choose the capacity that fits your needs, whether that is a pair of 1TB drives for basic document backup or larger drives for a media library. Once configured through its browser-based interface, the NAS appears as a shared drive on your network, making it easy for multiple computers and devices to access the same files.

A key feature is the integrated Lenovo/EMC Personal Cloud, which lets you reach your files from outside your home network without paying for third-party cloud storage. The PX2-300D also supports HD media streaming, so you can serve movies and music to compatible players throughout your home. With two bays, you can run RAID 1 for automatic mirroring that protects against a single drive failure, or RAID 0 and JBOD for maximum capacity. While it lacks the processing power and app ecosystem of higher-end NAS units, the PX2-300D covers the essentials—backup, sharing, and remote access—in a compact and affordable package.
