IDE-Flash or Compact Flash instead hard drive
Today is probably much wiser to use some Flash drive instead classic hard disk. It consumes much less power, is very small,
and prices are not big.
I tested above 16-bit IDE interface with Transcend's 128MB IDE-Flash drive (128MDOM40V). Current price is about 30 Euro,
what is bigger than price of Compact Flash, but you don't need IDE-CF adapter. It works very well, measured read speed is around 150KB/sec, access time
is under 1ms.
Compact Flash (CF):
interface worked well with SanDisk CF card. With Kingston I had problems - corrupt data. Solution is
putting 1Kohm resistor on line SELP (pin 37 of IDE conn.) to prevent ringing. Transfer speed of 128MB Kingston CF is same as with Transcend IDE-Flash.
