Test Hardware And Benchmarks

Protect Your Data! TrueCrypt 7.0a's Performance, Analyzed
By , Achim Roos

We used a test system equipped with Gigabyte's H55M-USB3 motherboard and an Intel Core i5-661 CPU to benchmark the AES performance of TrueCrypt version 7.0a. The CPU comes with the AES-NI instruction set and should provide a performance boost on encrypted systems. To determine just how much of a boost you can get, we employed three different test system configurations: an unencrypted system, an AES-encrypted system without acceleration, and an AES-encrypted system with AES-NI hardware acceleration. To make sure that the hardware acceleration is activated in TrueCrypt, go to the Performance Options menu and check the Accelerate AES encryption/decryption by using the AES instructions of the processor (if available) box.

We also used an OCZ Vertex 2.5” SSD as system drive in order to exclude the storage subsystem as a limiting factor, encrypting the entire drive. We first set up and installed all software on a hard drive, and then cloned it to the SSD for each run in order to make sure that each test was executed under the same conditions. We used Iometer 2008.08.18, PCMark Vantage, and SYSmark 2007.
