Adaptec RAID 2405 SAS / SATA Controller
To assess the performance of the Adaptec RAID 2405 SAS/SATA controller we will be running a total of three tests. Each of the tests will feature two drives configured in RAID0 with comparisons being made to Intel’s motherboard based ‘Matrix’ RAIDÂ controller. While not a directly comparable product to the Adaptec solution due to its lack of dedicated Memory and CPU, Intel’s Matrix RAID is without doubt the most widely used controller in the enthusiast community, and it will certainly be interesting to see how the two compare.

File Write & Manipulation
⢠WinAVI (with 500mb AVI file)
⢠Dummy File Generator (Write speed test with varying size files)
⢠Peazip (File Compression / Decompression)
OS & Gaming
⢠Racedriver GRID (Game loading times)
⢠Windows Vista x64 (Startup time)
With the exclusion of the Windows Vista (Startup Time) benchmark, all other benchmarks were performed from a fresh installation of Windows Vista x64 located on a separate Western Digital RaptorX master drive. This configuration ensured that the results from RAIDÂ arrays on test were not skewed by any random operating system disk access while also allowing us to perform all benchmarks on a completely blank Array.
