Ron, That's still comparing apples and oranges. Your 30 Meg RLL drive is simply the same mechanism used in a 20 Meg MFM drive that has been designed, tested and certified to run under RLL encoding. The controllers are obviously different thou. To get 30 Meg from a drive (MFM), you'd need more cylinders, or more platters on the mechanism…thus you'd be comparing two different drives. I can buy a card for my MS-DOS side HD that'll double it's capacity by compressing the data (similar to what ARC does) but the drive itself still only holds 10 Meg. Comparing that setup with a real 20 Meg drive isn't a valid comparison. With that said…since you insist on asking us for that comparison… I'd GUESS the cost differnce would be in the $50 to $100 range. That would include the cost difference between an MFM adapter and an RLL adapter. Don
