Note: These marks indicate that the Diamond FirePort 875 and the Adaptec AHA2940UW offer equal performance on a single drive test. Each of these cards has strengths and weaknesses independent of performance. The Adaptec card has a more complete BIOS setup low level format. The Diamond card requires a FD for various utilities. In this particular configuration the Adaptec card works fine at 75 MHz. However, at 83 MHz, I would bet on the Symbios based FirePort. November 1, 1997.  Note:  I retested these controllers a few months later.  At this time the Adaptec 2940UW showed a distinct advantage (Winbench97).  At this time I can't explain these conflicting results.
