I haven't used them but I did notice:
1) The "IDEfixTURBO" patch is OLDER then the latest version of IDEFix by eight months (Both in 1999). But it states that it will increase data transfer 100-300K. Might be worth a try for that. 
2) The "IDEFix_Patches" was put out last year (2010). So very very new in Amiga terms.
3) They are both patches which means you are changing the files at their core so you'll want to back up before attempting. this also means you'll have to DO the patching. No, the patching software does not come with the .LHAs but they do recommend one or two packages.
4) The second file is specifically for using CF cards on your Amiga. IF you don't have a CF reader, no need to do the patch. From the docs I can't quite tell if this is just to allow reading or to make "hot swapping" possible...
So I hope that helps in your decisions whether or not to patch. If you do try them, please let us know what to outcome is. Please?
Thanks mate, next week I'm setting up an A1200/060 wedge for WHDLoad with a 4GB SDHC Card as it's hard disk so I'll let you know how I get on.
