    For the X-T2, is there any need to buy the 300 MB/s memory cards instead of the 95 MB/s cards?

    I plan to occasionally shoot 4K videos, not sure if that makes any difference.

    For example:



    vs



    I would prefer to use the 95 MB/s cards if possible, since they are much cheaper (1/4 price).

    I don't know about video but when shooting bursts I don't notice that the 300 MB/s is much faster than the 95 MB/s.

    I can say for sure that my XPro1 write speed is so profoundly slow that no card will help it... it's slow from like 10 years ago when I used a D30 Canon with a 5 frame buffer..

    The only thing Fujifilm states on their website is:

    which requires a minimum sustained speed of 30MB/s. So, you should be fine either way.

    I use the SanDisk Extreme, not the Extreme Pro. They are even cheaper with no noticeable difference as far as I can tell.

    I don't take video with my XT2. For that I use my smartphone.

    There will be no difference for video on the X-T2.

    The big difference is shooting long, frequent, fast continuous bursts. The buffer will clear much faster and you will be ready to shoot sooner.

    If you don't do that you can save a lot of money on the cheaper cards.

    (Having said that there are two other advantages of the faster cards:
    - potentially much faster transfer from card to computer
    - future proofing - especially if you plan to get something like an X-T3 and take full advantage of its capabilities)

    I thought this too but I have both cards and don't really notice much difference between the cards. The 95 is better than 30 mb/s cards but the 300 doesn't seem to offer much benefit.

    Two weeks ago I was asking myself the same question and went for the cheaper option, getting two 64Gb Extreme Pro cards. After firing off heaps of both low and high speed bursts on my X-T3 at a running event last weekend I have absolutely no regrets with my choice. 95MB/s seems to be good enough for my needs.

    95 or 300 MB/s are read speed

    for saving shots to sd cards u have to worry about is the write speed

    True - but the 300MB/sec have a much faster write speed than the 95MB/sec cards

    I would buy this cheaper card in your place.

    The two cards this is about have write speeds close to the read speed.

    Thanks, so no real difference with 4K filming?

    If I remember correctly, the X-T2 videos are 100 megabits/second bit rate, correct? And 100 megabits would be 12.5 megabytes. So that would make sense that the 95 megabytes/second card is indeed more than fast enough. Thanks.

    Maybe even the 95 MB/s card is overkill? But I guess the price savings between 30 MB/s and 95 MB/s cards are not as substantial.

    This calculation is helpful but
    there is always a lot of overhead in parts of the pipeline and you also don't know the measurements were done so it's always a good idea or verify.

    Plus the 90MB/s card often are only 90MB/s for reads and much slower for writes. A few of the Sandisk I tested here were between 80 and 90MB/s for read, about 30 to 35MB/s for writes.

    The 95 MB/s cards have almost the same write speed. They are unusual in that aspect.

    How much do you use the cards?
    How fast is your card reader?

    If you fill up the cards rapidly with photos and video then I prefer the faster UHS-II (300 Meg) cards.
    I honestly have not seen much improvement between the UHS-II and UHS-I (95 Meg) cards, my X-H1 will bottleneck if I do too many 5 fps shots. Both cards work great at 3 fps. My X-Pro2 uses UHS-1 cards and I occasionally do 4k with it - no issues.

    Where I really like the UHS-II cards is getting the information from the card to the hard drive which is the reason for me asking about the card reader.
    Card reader on my laptop can easily read the UHS-I cards at around 80~90 Meg but the UHS-II cards are throttled to about 130~150 Meg. Using a thunderbolt card reader and I get 200~240 Meg.

    Not the ones I tested a few years ago. I have some that do, but they state 90MB/s r/w. Not just 90MB/s. So, be aware.
