I partially agree with Boingboss,
Having installed may SCSI controlers by many manufacturers generally on an A2000 the A2091 was the besat bet. Some GVP SCSI controllers were problematic depending on the Kickstart and Controller ROM Revisions.
On the A4000 the A2091 is the chaepest solution, it works but is slow. The card performs much better with a GuruROM.
I finally got a Warpengine 4040 for my A400 and am much happier with performance.
