Rare pierces Posted November 28, 2017 #2 Share Posted November 28, 2017 Great specisls everywhere on SD memory but ... SanDisk uses color coding - what is the difference and what would you buy - the red/white/blue disk, the silver ones, the yellow ones, the black ones? On most of the card types, SanDisk not only states the Speed Class and U-Type but includes the Read/Write speed. Red/White/Blue base SDHC/SDXC card - Class 4 (Min. 4MB/s read/write) (The Yugo GL of memory cards.) Silver/Red Ultra SDHC/SDXC - Class 10 (Min. 10MB/s read/write) - Up to 80MB/s read speed for 16GB-128GB cards and up to 40MB/s for the 8GB cards. Write speed is lower (usually about half). Silver/Red Ultra Plus SDHC/SDXC - Class 10/U-1 (Min. 10MB/s read/write) - Up to 80MB/s read speed for 16GB-128GB cards. Write speed is lower (again, about half). Yellow/Red Extreme SDHC/SDXC - Class 10(Min. 10MB/s read/write) - U-3 (Min. 30MB/s read/write) - Up to 90MB/s read speed for 16GB-128GB cards. Write speed is 40MB/s for 16GB-64GB and 60MB/s for 128GB-256GB cards. Will record normal 4k video nicely and exceed the burst speed of most cameras. Yellow/Red Extreme Plus SDHC/SDXC - Class 10(Min. 10MB/s read/write) - U-3 (Min. 30MB/s read/write) - Up to 90MB/s read speed and 60MB/s write speed for 16GB-64GB cards. Will record normal 4k video nicely and exceed the write speed of most cameras. Black/Red Extreme Pro UHS-I SDHC/SDXC - Class 10(Min. 10MB/s read/write) - U-3 (Min. 30MB/s read/write) - Up to 95MB/s read speed and 90MB/s write speed for 32GB-512GB cards. Will record normal 4k video nicely and exceed the write speed of all but a few cameras. Black/Red Extreme Pro UHS-II SDHC/SDXC - Class 10(Min. 10MB/s read/write) - U-3 (Min. 30MB/s read/write) - Up to 300MB/s read speed and 260MB/s write speed for 32GB-128GB cards. Will record raw 4k video and exceed the write speed of all current cameras. Note that if you decide to go with the 300MB/s cards, you will not get any benefit in burst speed or card clearing over the even the Ultra Plus cards and you will need a USB 3.0 or 3.1 reader to make use of the speed for downloading. The UHS-II cards have a second row of pins used by compatible UHS-II readers and equipment but are backwards compatible. Hope this helps.

tommui987 Posted November 28, 2017 Author #3 Share Posted November 28, 2017 Hope this helps. Dave As always! Probably me, but I distrust any chip going beyond 32Gb thinking that it will fail in some manner or the other! Link to comment Share on other sites More sharing options...
Rare Oviedo32765 Posted November 28, 2017 #4 Share Posted November 28, 2017 Dave beat me to explaining the color differences of the cards. Here's a link for an explanation of the numbers on a memory card - https://www.bhphotovideo.com/explora/computers/tips-and-solutions/numbers-your-memory-card The best advice I can give on which to buy is consult the User's Manual for your camera. There should be a section that lists the approved memory cards for your camera. Then you can compare the price of the cards, read/write capacity and storage size vs the cost of each type card.

gambit57 Posted December 13, 2017 #5 Share Posted December 13, 2017 If you shoot RAW, I wouldn't go lower than Extreme Plus. I've tried Extreme and below as well, which is how I've settled on Extreme Plus as the bare minimum. Cameras used were Nikon D7000 and D750. I had a D200, but I don't think I ever shot RAW on it.
