+====== One-for-All good article on cards ======

+====== Card Type for Camera Storage======
+  * most common type: SD card
+  * high end sports camera: CF card
+  * high end video camera: 2.5 inch SSD
+  * other cards: rarely used
+====== SD card ======
+**There are 3 size of SD card**
+  * **Full size SD: most common type for cameras**
+  * miniSD: rarely seen nowadays
+  * microSD: most common type for slim compact cameras and smart phones
+**We are mainly talking about Full size SD card From Here;**
+**SD card has 3 property to consider when choosing**
+  - capacity: how many GBs of storage
+    * category label based on capacity:
+      * SD: 1-2 GB
+      * SDHC: 4-32 GB
+      * SDXC: 64-128 GB and upto 2TB
+  - Maximum Read/Writing speed: how fast it can quickly move in/out data
+    * category label based on max R/W speed: (Mbps=mega bit per seconds, MBps = mega Byte per second = 8 Mbps)
+    * normal lower uhs-i and lower cards use mbps (bit) to make number looks bigger, each gen speed also different
+    * while higer uhs-i and uhs-ii card use MBps (Byte) as they are next gen card fast
+      * R 280MB/s W 250MB/s : Video Pro
+      * R 95MB/s W 90MB/s : Photo Pro
+      * R 90MB/s W 60MB/s : Photo Burst Good
+      * R 90MB/s W 40MB/s : Photo Burst Good
+      * R 80MB/s          : Good
+      * R 48MB/s          : Average
+      * below             : Low
+  - Example chart :
+    * for 4K video, 100mbps, = 12.8MBps
+    * for 4k video, 60mbps, = 7.5MBps
+    * for FHD video, 28mbps, = 3.5MBps
+    * so V30 card and 30MBps write is more than enough for common 4k video and below
+    * while 60MP high res sensor burst shots will require far more write speed than video.
+  * uhs-1 limit: 104MBps
