But the fact remains these cards are overpriced. That almost makes our entire dialog moot seeing fewer people will buy them for that reason, and for the reason you also need a 48GX too.

Hi,

The link Sylvain posted agrees with other sources I read up on FRAM has a read/write limit somewhere between 1-10 trillion cycles. While this is certainly a lot of cycles, when this is applied to a program constantly running off the card It could theoretically become an issue in a couple of years depending on duty cycle of memory access.

I intended to use these cards in my HP48SX running a low power ham radio monitoring station on a continuous basis (hence my concern for a large amount of read cycles). In this regard the HP48SX is better suited than the HP48GX due to it's lower power consumption (longer battery life). I do have an HP48GX, however I've grown to like the SX better. For heavy calculations I use the 50G
