 “[The D0204's] speeds are officially blazing, and are courtesy of the USB 3.0 connection; if your PC is lacking these ports, the D0204 even includes a USB 3.0 PCI Express card, with 2 x USB 3.0 ports.”

 “The Thecus D0204 DAS Server ranks up to an impressive 90 points on our iTrends character-scale system, and the last points are lost because the solution cannot be bought in Denmark…The D0204 DAS server is quite impressive, and I was surprised you can have this many features in a USB powered device. Why hasn't this been done sooner? Performance, yes we do not need to talk about that when the USB3.0 runs at 100MB/s+ even with a pair of cheap hard drives installed.”

"The Thecus D0204 is a very compact yet simple to use RAID external hard disk drive that should be a hit with people who have huge amounts of important data to backup. The device does make backup a whole lot more reliable thanks to its RAID mode support. The smaller size of the device will require less energy to power and less space compared to other external hard disk drive enclosures."

"The D0204 can accommodate two 2.5" hard disks and can even support SSDs, but don't think that it's just an external hard disk enclosure with two bays. The D0204 supports Clear, JBOD, RAID 0 and RAID 1, and provides 5Gbps of USB 3.0 bandwidth, allowing excellent performance numbers for RAID 0… With a small form factor and a small AC adapter, it is truly a convenient and mobile external hard disk array."

The age of USB 3.0 is almost here. Today, storage leader Thecus® Technology is proud to announce its first portable storage device featuring the new USB 3.0 standard – the D0204. With massive storage capacity in a tiny package no larger than a paperback book, the D0204 delivers impressive data security and performance with an integrated USB 3.0 port, making it the most powerful and versatile portable DAS on the market.

The D0204 is a small and compact direct attached storage (DAS) device. Wrapped in a housing measuring a mere 86mm x 55.3mm x 132mm, the D0204 may appear to be a mere portable hard disk at first glance, but peering inside this tiny form factor reveals a powerful storage unit.

Headlining is its integrated USB 3.0 port at the back of the unit, which grants the D0204 data transfer speeds of up to 5Gb/s – ten times the speed of USB 2.0. With USB 3.0 built-in, users can transfer files to and from the device at unprecedented speeds with a USB 3.0-enabled computer. Of course, the D0204 is fully backward-compatible with USB 2.0 and USB 1.1 standards, which means you can use it with virtually any USB-equipped device.

Users can install up to two SATA hard disks using the D0204's two 2.5” SATA bays, which means a total storage capacity of up to 1.5 terabytes! The D0204 even accepts the latest solid state drives (SSDs), offering users impressive data performance with no moving parts that could break or malfunction. Users can even swap hard disks while the device is running thanks to the D0204's hot-swappable drive bays

Of course, the Thecus® D0204 is a complete storage solution that's also easy to use. To manage all of this storage, users can choose between RAID 0, 1, and Large to further enhance data security or performance. All of the D0204's features can be administrated through its intuitive Windows Utility. With this utility, D0204 users can both set up and manage their D0204, making this powerful storage device also one of the friendliest around.

“With full USB 3.0 compatibility, the new D0204 brings incredible performance and data protection to a remarkably tiny and easy-to-use device,” said Florence Shih, Thecus® Technology General Manager. “Offering impressive storage capacity in a small size, the D0204 is the ideal storage device for the user on the go.”
