Western Digital Sentinel DX4000 Small Office Storage Server



The Western Digital Sentinel DX4000 is a small office storage server designed for file sharing and backing up data on as many as 25 computers. While the thought of working with a server may be daunting for novice and immediate users, setting up the Western Digital Sentinel DX4000 is simple and easy, thanks to its plug-and-play installation. The administration dashboard guides you through the process of adding users, granting data access, creating shared folders and scheduling backups with ease.

The Western Digital Sentinel DX4000 may be user friendly, but it doesn’t skimp on data protection. Using Western Digital enterprise-class hard disk drives, the DX4000 supports RAID 1 and RAID 5 protection, so all your important files are stored in redundant hard disk drives. If one of your hard drives bites the dust, you can easily hot-swap it with a replacement without having to turn off your server. No downtime required.

Speaking of no downtime, you won’t experience any while connecting to the DX4000 over the Internet. With dual 10/100/1000Mbps RJ-45 ports, the ultra-fast Gigabit Ethernet interface delivers read and write speeds of up to 85MB/s. That’s three times faster than a typical NAS solution, which is usually 30MB/s. You don’t have to worry about lag when using the built-in DLNA media server to stream media from your shared library over the Internet.

The Western Digital Sentinel DX4000 comes in four different capacities, which are 4TB, 6TB, 8TB and 12TB. Pick one up today and get rid of all those unnecessary USB flash drives.
