M90 ExpressCard 54: PCl or PCLe?

Thread Starter 
I don't know the difference between the ExpressCard 54 types, but have an M90 and want to dedicate the slot for a Compact Flash reader. Does the M90 use PCL or PCLe and is there any real difference between these two? I use 16GB UDMA Compact Flash for my camera (currently use SanDisk Extreme IV 45 MB/s). I'd of course prefer the faster reader if it'll work in my M90, as CF cards keep getting faster. A downside to the first card is it isn't available in US directly, but can be had off eBay.

This option is the PCLe:

This one is slower PCl:

Here's another, but gets some mixed reviews on fit & function.

From what I understand you can use any Express card 34 and 54 mm in size using a 26 pin i/f.

So as long as your buying a adaptor that works with your compact flash card you should be OK

Yes, but an expresscard that uses USB2 is going to be no faster than an external USB2 reader. There is only a benefit if its faster to read or to write.
