www.buy.comThecus N0204 miniNAS - World Smallest NAS: 2 x 2.5" SATA HDD, w/ iTunes & Web Photo Server Support, Raid 0, 1, JBOD The N0204 miniNAS - the worlds smallest fully-featured NAS device. Measuring a tiny 132 x 88 x 63 mm exterior, one could easily mistake the N0204 as a regular external hard drive. But look closer and you will see a very capable two-bay NAS device that fits right in the palm of your hand. The N0204 houses two 2.5 SATA hard disks, providing up to 1TB of storage. You can manage this storage with your choice of RAID 0, 1, and JBOD, making the N0204 the most robust pocketable storage device in existence. And because its drive bays are hot-swappable and feature auto-rebuild, you can change a hard disk without powering down the unit. The N0204 even comes with Thecus Nsync for remote replication as well as the Thecus Backup Utility for total data security. With huge storage, RAID functionality, and advanced data safeguards packed into a tiny device, the N0204 is in a class all its own.
Tiny but mighty, the N0204 comes with many of the features and functionality possessed by its much larger cousins. For starters, the N0204 can function as a complete media hub with its built-in iTunes server, photo web server, and media server. With the built-in media server, you can watch your videos, pictures, and music in the N0204 by using any DLNA compliant media players. Plug in a USB web cam, and the N0204 turns into the worlds tiniest home surveillance server, allowing you to preview, capture and schedule image snapshots up to 640 x 480. Add to that support for both Windows and MAC OS operating systems and a whole new user friendly Windows Utility to set up and link the N0204 with your PC easily, and youve got some serious storage that you can whip out of your pocket and plug into virtually any network.
The N0204 miniNAS is a marvel of engineering. With advanced energy-saving capabilities, the N0204 only uses between 25~30% of the power compared to traditional two-bay NAS devices. You can even schedule power on/off for better power management. The N0204 also features whisper-quiet cooling, which means low temperatures and even lower noise during daily operation. A convenient USB 2.0 port in the front and the one-touch copy allow you to copy the contents of a USB storage device to the N0204 with a single button press. You can also copy data from the N0204 to any USB disk for data exchange. The N0204 supports USB printers, external hard disks, USB web cam, and even works with USB WLAN adaptors, allowing you to give this tiny NAS device wireless capability.
RAID Protection In Your Pocket Don't let its small size fool you - the N0204 miniNAS comes with RAID 0, 1, and JBOD support, which means that you can optimize your storage for speed or security. Never before has there been a storage device so small, yet so flexible.
