I am afraid that Vampire is far too fast for any CD-ROM...

Yes and NO

Of course CDROM can work just fine.

But the FASTIDE Mode which CF cards support - is not nsupported by CDROMS. And the FASTIDE mode is from CF card manufactures only guanteed to work if the CF is direct connected to the HOST (single CF!)

So mind that if you add a CDROM you will have to run the whole in slow mode.

What about DVD Roms?

Good to know. I was planning to add a CD/DVD drive to my V500 using 3-way IDE as well.

Will the speed of the SD Card ever get as high as the IDE or is it maxed out already at about 4Mb/s (vs the 10Mb/s of FASTIDE)?

The FASTIDE Interface does support over 25 MB/sec.
The current limit of 11-14 MB/sec is a pure Software limit => stupid AMIGA SCSI.device. This could easily be upgraded with software patch.

Oh thats sounds great...
Thanks for your answer...
The speed isn't for me at first place...
Do I need special drivers or not, i works with os3.9?

Does that mean the sdcard will be a lot faster too?

Hehe.. i have been asking this question several times and no one seems to know anything about it. ;)

If someone writes a new IDE driver this is no effect on the SDCard and the other way around.
But if both are new written...

What we are questioning is the expected speed of the SD interface. Is 4mb/s max speed? What is the theoretical limit?

Cheers

If both the SD Card Reader driver and the SCSI.device are re-written that would greatly improve performance of both. Would it also be possible, while re-writing to implement or improve support for CDRom drives on the Fast IDE as well as increasing the Fast IDE speed to 20MB/s-25MB/s?

Ideally I would run with a CDROM and CF on the IDE and SDCard. I was just wondering where the best setup would be, both now and in the future. Do I have a small boot partition on IDE CF and have all the data on SDCard for fast access? or put everything on the IDE CF and just use the SDCard as backup storage?

  Its difficult time. SD Card driver is currently best solution, all can be done there as it is hard drive, just faster and with highest priority it will get faster :-)

You could back your CDs of games and apps to ISO files and copy CDs with data to HDD and then just transfer them to SD Card, if you can do that now.
  I suppose these tools could help, if you dont have your own preferences

I've tested with an old cdrom reader: it works :)
With old DVD reader, no luck but i don't know if it's the reader or the vampire which is incompatible...

Thank you. That's good to know about the internal IDE Zip250 drive and the cdrom drive. I intended to use the cdrom but a zip drive would great for data transfer operations. I have a few Zip drives and spare Zip disks laying around. It may be time to put them to use. ;-)

Sorry to revive this threat, but if I understand correctly I can do the following.

Connect an IDE cable to the V500 IDE connector and attach both a CF card reader and a CDROM. However the CF card reader will be slow, since the CDROM is a bottleneck?

Just asking because I'm considering to use my Vampire with an Amy-ITX.

This isn't a threat at all :-)

No, it is a common misunderstanding that connecting a CDROM to the same IDE interface as a CF Card will slow down the CF card.  But this isn't the case at all.  I have a CDROM connected on the same IDE port as my CF Card.  No problem.
