Thread: IDE to compaq Flash is pc=amiga?

Tried the adapter mentioned above, and on both the Amiga and PC it's recognized and works fine (not as fast as a CF Card trough, but maybe because of the SD card used, it's a cheap one... 2GB). Will buy a 4GB and a fastest one.

I think CF cards are generally faster than SD cards. And PC Pro recently ran an extensive test comparing speeds of different makes and models of SD card and discovered that the so called fast SD cards that claim things like 66x faster speeds were not actually that much faster than cheaper standard speed ones. The only real factor is quality as good quality known makes will be reliable and retain your data, whereas cheap or unknown makes will corrupt or stop working more often.

You are probably right. But here in Portugal CF cards are much more expensive and smaller in size compared to SD, so i don't mind loosing some speed. On the PC the test was made using a standard ide cable so the speed was limited to pio modes, with 80 wires cable the adapter is capable of UltraDMA data transfer speeds, have to test with 80 wire cable. On the Amiga doesn't matter as the speed of the transfers with an A1200 020 6mb is probably the same with CF cards or SD cards... probably... .

It definitely doesn't matter so much on the Amiga. Unless you upgrade an A1200 with one of the fast buffered IDE interfaces (the expensive ones that also attach so some of the Amiga's custom chips), the standard A1200 IDE port, or a cheap standard buffered IDE interface will only be able to sustain a transfer speed of a couple of MB at most.
