Solid State HD for A1200 project

I don't think you should encounter many bumps providing you follow the guidelines that are around.

The easy way is to get a kit like this: http://amigakit.leamancomputing.com/catalog/product_info.php?products_id=883

Alternatively you could get a separate compact flash and adapter.
This is a handy thread on eab to look at:

I would take the following approach
1) Get yourself a CF to use as backup/transfer disk (like this: http://amigakit.leamancomputing.com/catalog/product_info.php?products_id=440)
2) Get yourself a CF and adapter to use the CF as harddisk
3) First lha your harddisk contents to the backup CF using the PCMCIA->CF solution.
4) Hook up a CF to USB adapter to your PC.
5) Install the CF to use as SSD using WinUAE.

6) Extract the backup lha to the newly created CF harddisk (using winuae)
7) Put the CF harddisk in the A1200

That's about it.

I know this is not a step by step for dummies. It just gives you a direction. Google around. This has been done many times. I'm using a 4G CF in my A600 as harddrive. Works like a charm. In case of trouble, just ask.

True, IDE is the bottleneck. The A1200 IDE is some old PIO mode. So any compact flash will saturate that on read. Modern compact flashes even write faster than the A1200 can push the CF. I'd always go for the cheapest option. CF's are dirt cheap. My 4G CF in the A600 cost me 10 euro. But you'll have to add an adapter.
