+==== Camera compatibility ====
+==== In-cam format and card size ====
+===== FAT32 =====
+File system used as default by small and medium sized data storage cards. Supported by all cameras able to run ML.
+Supports file size up to 4 GB.
 ===== Incompatible cards =====

-They won't work at all. ML's process of checking for a bootable card is incompatible with EyeFi-firmware (yes, your EyeFi-card has its own firmware). If you want to use first-gen EyeFi with a camera with ML bootflag set: Nope, it wont work at all. You have to uninstall (=remove cam's bootflag) before using such cards. \\

 ML devs aren't able to fix this issue.\\

+==== Sony 94MB/s 32 GB SDHC ====
+Not exactly incompatible but with strange performance issues in some (not all!) Canon cameras. See https://www.cameramemoryspeed.com/reviews/sd-cards/sony-32gb-sdhc-memory-card/ for details.\\
+Recommended not to use them because of known inconsistencies. (Confirmed by user andy kh on 70D).\\
+Because they are not longer in production you will likely never meet one. All other Sony cards (including successor 95 MB/s variety) are working without hick-ups.
 ==== SD-to-CF adapters ====
 Frequent issue: Trying to make an SD-card work in a CF-card slot by inserting card into an adapter. Frankly, most adapters are just crap. There are some adapters able to work with ML's method of checking for a bootable card. But most will just get your cam stalled. It is strongly recommended **not** to use SD-to-CF adapters with Magic Lantern. ML project does not support it and in case of failure you won't get any help.\\
 There is no issue on ML's side using microSD-to-SD adapters.
@@ Line 15: / Line 97: @@
 For ML it doesn't make a difference: microSD-to-SD adapters do not contain any compontents but contacts and very short wiring. There is no perceivable performance drop with adapters.\\
-Exception: Performance drop will indeed be seen if used with very, very cheaply made adapters where some data lines are simply not connected. I haven't come across such an adapter my whole life. All manufacturers I know ship their microSd-cards with an adapter and those offer a full set of data lines.

 To be shure do some benchmark runs with/without adapter using a cardreader and your PC. If a data line is missing performance will drop by a huge margin (25 percent and higher).
-===== UHS-II cards and ML =====
+===== UHS-II cards =====
 At the moment no ML supported cam does have an UHS-II slot. An UHS-II card inserted into a non-UHS-II device (as your ML camera) will run in a so called "UHS-I compatibility mode". Performance in UHS-II and UHS-I modes are completely independent! To make it absolutely clear: A card with stellar UHS-II performance may (or not) have an unsatisfactory UHS-I performance. Examples for this: \\

-Don't get me wrong, most current available UHS-II cards do perform pretty well in UHS-I compatibility mode and are only a tad slower compared to fastest UHS-I cards. But you have to take special care if you select UHS-II cards for your UHS-I camera if you go for performance. And most benchmarks available on the web don't make a difference and test in UHS-II mode only.

+About overclocking: ML project has no reliable data how well an UHS-II card in UHS-I-compatibility mode runs with overclocking. We simply cannot say how reliable it is or if it runs smoothly without killing your precious card.
+===== Storage size: Mega and Giga confusion =====
+> Incomplete
+Ever wondered why your 3 TB disk appears as 2.72 TB in Windows? And your 128 GB card as 119 GB? \\
+Both numbers are right, you haven't been tricked! Or have you? \\
+Storage manufactures count this way:\\
+Bytes = 1 kByte\\
+kBytes = 1 MByte (= 1000 x 1000 Bytes)\\
+MBytes = 1 GByte (= 1000 x 1000 x 1000 Bytes)
+Computer programmers count this way:\\
+Bytes = 1 kByte\\
+kByte = 1 MByte = 1024 x 1024 Bytes = 1,048,576 Bytes\\
+MByte = 1 GBytes = 1024 x 1024 x 1024 Bytes = 1,073,741,824 Bytes\\
+For computer programmers it is absolutely logical to count in numbers based on 2. And 2^10 is 1024.
+(Fun fact: For a long, long time storage manufacturers and programmers used the same binary counting. Confusion began when storage manufactures changed to decimals.
