Around December 2009 Acekard made a small hardware revision to the Acekard 2.1. As a result from this change, AKAIO and the official firmware demonstrated serious saving issues. Team Acekard was unable to understand how the hardware change had altered their firmware’s behavior. The AKAIO team, with the help of its BETA testers, was able to fix the issue. As of AKAIO 1.6 RC3 these cards are fully usable. Team Acekard has applied this fix to the official firmware as well, which means that as of the writing of this review the Acekard 2.1 is fully functional once again.
I have received confirmation that a new run of the Acekard 2.1 is currently in production. Acekard has gone back 1 hardware revision to ensure continual functionality with the two firmware choices. This new run is simply the same Acekard 2.1 which was produced before December 2009.
