This looks like a very interesting mod, I don't know enough about CF cards to comment on how stable they are but I would imagine they are similar to SD cards? With this in mind I wouldn't suggest stressing it too much, I've had many SD cards become corrupt due to over-stressing - they really aren't designed to work as base for an operating system. Hope it works out for you though and I look forward to seeing your progress with this project
SD cards are a no go , because reasons you mentioned. CF Cards are more reliable.
Every test you make you can clearly see an IOPS advantage for CF.
Though there are differences. I would not go that far and buy an SLC version. How many Times do you really load in a game ?
I loaded in a couple Xbox game i play and some ROMS will find a place also.
Ones done i delete and play something new. So this way it will stand about 10 Years or more. Until than its time to move on.
With 30 gigs you can put in about every game from a Cartridge up to N64.
For me it was just a handy solution. And im Happy with the results.
It will became a silent knight of gaming for me XD
It worked out for me.
