In this review, we'll be taking a look at Tsunami's e-DATA 3500 NAS BT enclosure. Although the unit looks like a 2-bay enclosure, it actually only fits one SATA hard drive. It supports both USB and eSATA, and features one RJ45 network connection. The enclosure has a 80mm fan on the top of the casing for cooling and allows sufficient airflow. There's no RAID support and no hot-spare capabilities.

"The Tsunami e-DATA 3500 NAS BT enclosure will appeal to a lot of SOHO users. It's the price and features that will make it attractive. The build quality wasn't as bad as I thought, it's easy to install and configure ... what's more, it can be used as a standalone external hard drive or a portable NAS device. It supports File-Sharing, FTP and Bit-Torrent services ... a great little portable NAS solution that's extremely affordable."
