ch habe mir gedacht, es wäre vielleicht ganz interessant zu wissen, welcher Datendurchsatz mit CF-Karten als Festplattenersatz in der Praxis im Amiga erreicht werden kann und ob es Unterschiede zwischen den verschiendenen CF-Kartenmodellen gibt.

Wichtig dabei wäre zu wissen welches Amiga Modell, Turbokarte, IDE oder SCSI Kontroller und OS. Als Testsoftware würde ich SCSISpeed vorschlagen, damit die Vergleichswerte stimmen.

Meine derzeitigen Erfahrungswerte:

 

CF-Karte: 1GB Transcend 80x
