[Leica] SD Card for M Mono Type 1

Fri Aug 28 10:50:37 PDT 2020

These Sandisk Extreme Pro ( not Plus as I originally wrote...) cards 
work just fine.  Regardless of what Leica said in 2009.  I have an M9 
and an MM ( to be clear, the CCD Monochrome camera) and the cards work 
in both.  Even the 128GB cards.  ( I actually tried a 512GB card, and 
that worked as well.... but I am not sure the camera could "reach" all 
512GB....)

In the early days of SD cards, there really was no standardization in 
specs, and the camera makers incorrectly wrote SW to access the cards in 
specific ways.  So certain cards worked in some cameras and not others.

You can try to find new cards that meet the published specs of the MM or 
you can take my experience and use the Extreme Pro cards, and order then 
on Amazon for $20 each and see what happens......

The 32GB card is $13...

170MBPS read speed.....

I have both and use them in my cameras.  They work just fine.

Using a phrase from Ted... KISS.

BTW, you DID ask what works..... and these work.

A little EE background....

The SD card only exists for cards with sizes up to 4GB  ( the original 
spec, and the most problematic from a camera users perspective)

The SDHC Card exists up to 32GB  ( Card Spec issued in 2006)

The SDXC Card exists up to 1TB. (Card Spec issued in 2009)

These limitations are both physical ( the internal physical wiring and 
and connections) as well as SW ( what and how the camera maker designed 
the camera to operate) to access the card.....

BUT you do not know what the maximum capacity a certain camera can take 
because the SW may or may not "reach" further than the stated spec.......

You can put a 1TB card in your MM, but the camera MAY only reach 32Gb of 
data..... and you will not know until you try it.......

Note that only the words tell you what the card is... SD or SDXC or 
SDHC.... they all look the same.......

I could write a lot more, but I am pretty sure everyone has now fallen 
asleep.....
