We are working as fast as possible to complete our new firmware release! It is a major upgrade (yes, it will work with your existing DOSonCHIP hardware) that includes new architectural innovations to dramatically improve throughput. It departs from our existing host interface in order to improve efficiency and enable a stable path for future improvements. In addition, we will be supplying royalty-free host-side source code in C to simplify development.

We have completed testing on read rates and have a peak throughput of 300 KBytes/s (sustained over a 512 byte sector), and an initial test of a long sustained read over 100 KBytes/s. This is similar over both SDHC and SD cards.

We are currently finishing debugging the write function and should have test numbers shortly. We are expecting similar speeds as read.
