More Data + Larger, Faster Storage = A Forensic Nightmare

Dealing with big storage and bigger data presents today’s forensic examiner with greater challenges than ever before. Facing this challenge requires a radically new digital forensic bridge product – the UltraBlock USB3 Write Blocker.

Forensic Data Acquisition with the new T8u Forensic USB 3.0 Bridge

From the outside, the new UltraBlock USB3 Write Blocker looks similar to our venerable UltraBlock USB Write Blocker V2 – but the similarities end there. Use this device and you’ll realize it’s unlike any other USB3 write-blocker on the market today. It excels when imaging USB 3.0 flash drives and large, multi-terabyte USB 3.0 hard drives, but it supports any USB device that conforms to the mass storage “bulk only” specification. It is compatible with older USB 2.0/1.1 devices.

The UltraBlock USB3 Write Blocker presents various bridge and device information via an integrated, backlit LCD. This display also allows users to select and access multiple Logical Units (LUNs) on storage devices. Its powerful combination of USB 3.0 technology and new bridge electronics provide the speed you need to cut through the worst data collection backlog.

Forensic Imaging In Excess of 300 MB/second

Improving imaging speed is a central goal for Tableau product developers. They test their products in controlled yet real-world conditions to verify that each product achieves the highest performance possible. Using industry-leading forensic imaging software, we measured data transfer in excess of 300 MB/second (dd/RAW output data format while simultaneously calculating MD5 and SHA-1 hashes). No other USB 3.0 write-blocker available today matches the high-performance of the UltraBlock USB3 Write Blocker.

Not All Forensic Imaging Software and USB3 Controllers are Created Equal

Our product testing shows that forensic imaging software, USB 3.0 computer controllers, and operating system driver configuration can have a significant impact on its imaging performance. Whether you image compressed (.e01 or .ex01) or uncompressed (dd/RAW) data formats, ensure your software is up to the task by using a modern, multi-threaded software imager such as Tableau Imager (TIM) and EnCase Imager with UltraBlock USB3 Write Blocker.
