Synology just launched a new addition to its lineup of network attached storage units for the home/ small office market with the release of the DS409slim. With room for up to four 2.5" drives the DS409slim can support up to 2TB of storage with a footprint of only 120 x 105 x 142 mm. The little NAS is not only small, but it's also has a small appetite for power, using an average of 19W under normal operating conditions with all four drives installed.

Maybe Synology should have called it the 'Little Giant' because, despite its diminutive size, the DS409 sports some big features like hot swappable drives, a 1.2GHz processor and 128MB of memory. The unit also features a Gigabit LAN port, two USB2.0 ports and an eSATA port. The DS409slim supports basic, JBOD, RAID 0, RAID 1, RAID 5, RAID 5+Spare, RAID 6 volumes and comes with features like RAID volume expansion and RAID level migration not normally found on units this size.

The unit uses Synology's Disk Station Manager 2.1 firmware, an AJAX-based user-friendly interface, featuring a BitTorrent download manager, a multimedia server with UPnP support for the Sony PS3 and Microsoft Xbox360 and several backup features.

Synology said it is currently shipping the DS409slim and a quick review of online pricing showed it's available for around $400US.
