  1. Title, team, advisor, client info • Title: USB 3.0 Write Blocker • Team members: Chen Zhao, Elphas Sang, Yan Fang • Faculty Advisor: Dr. Zhang • Client: Electronic Crime Institute - Des Moies Area Community College

  2. Project goal/problem statement • Currently many USB 2.0 to Sata write blocking devices exist, but none for USB 3.0 • This project is to develop a blocker device for USB 3.0 • This device may drop writing commands to a USB 3.0 without affecting reading operations

  3. Parallel processing units Conceptual diagram/Use-case scenario SATA HDD Data Input USB 3.0 STD-B Parallel processing units USB 3.0-SATA Bridge (Command Filter) Entry Unit SATA Parallel processing units

  4. System Block diagram Writing Branch Parallel processing unit Operation declined feedback Parallel processing unit Branch Equal Buffer Reg1 Buffer Reg2 Dataflow_in Dataflow_out Parallel processing unit Reading Branch Command Filter

  5. Functional Requirement Data Bridge between USB 3.0 and SATA This device acts as bridge for dataflow Lossless Data Transfer Data transfer does not allow any information loss A speed approximately at 300 MB/s This is the USB 3.0 standard, under the constrain of SATA capability Protection Feature can be enabled/disabled There is a switch on/off to enable the protection feature. The filter will work only when the feature is turned on

  6. Functional Requirement Cont’ • No Cryptography Information is not secured • Efficiency Comparing the general power consumption of USB 3.0 to the USB 2.0, USB 3.0 should have low power consumption as possible

  7. Non-functional Requirements • Product Quality (Reliability): the ability of a system or component to perform its required functions under stated conditions for a specified period of time. It is often reported as a probability • Portability:- Ability for the user to install a software on all necessary platforms, and which platforms that is expected to run. - The ability for the device to be moved from point A to point B • Maintainability – e.g. automated updates, software updates, • Testability: testing by the user once the device has been approved of it functions. • Usability: Ease-of-use requirements address the factors that constitute the capacity of the software to be understood, learned, and used by its intended users. • Environmental Constraint: This include any physical constrains to the environment.

  8. Tasks, Responsibilities and Schedule • VHDL coding • Documentation/recording problems • Hardware Design • Communication with client • System Generation and Verification plan, Testing

  9. Schedule in Detail

  10. Cost Estimate • Total Budget: $2000.00 • Building Board (HTG-V5-DDR3-PCIE-FX70T) $1695.00 • Accessories (HTG-COM-MDL) $495.00 • Total Cost(for current situation): $2190.00

  11. Potential Risks and Mitigations • Schedule Risks Development Board Choice • Technical Risks Difficult project modules integration • Operational RisksRisks of loss due to improper process implementation • Financial Risks Budget may not be sufficient
