I personally prefer UHS-II v90 cards because I often shoot in burst mode, and then the faster write speed is really beneficial.So, I don't NEED to buy cards which Fuji recommend - but I SHOULD buy cards that are UHC II spec and at least V60. Such as this one? https://www.amazon.co.uk/Integral-U.../dp/B0845GWK51?sp_csd=d2lkZ2V0TmFtZT1zcF9tdGY

Do you think they wont try sell you a faster card thoughJust thought - there's a Fuji demo day at a nearby camera store which I have been invited to. I will ask them what the limitations really are. In theory UHC II is UHC II.
I don't know that particular card manufacture, but general the faster the better.So, I don't NEED to buy cards which Fuji recommend - but I SHOULD buy cards that are UHC II spec and at least V60. Such as this one? https://www.amazon.co.uk/Integral-U.../dp/B0845GWK51?sp_csd=d2lkZ2V0TmFtZT1zcF9tdGYYour 64GB card are way too slow. Its write speed is 3 times slower than your 128GB card. One is a U1 card = 10MB/s, the other is a U3 (v30) = 30MB/s.How do I know if the card is 'up to spec'? It's a 64Gb SDXC card made by Kingston. What else do I need to know?
Here's a picture of the 2 cards. 654Gb is the one that failed. Although it's now working just fine.
Reed about the symbols you see on your cards and what they represent here:
Understanding SD Card Speeds, Types and Important Symbols (shuttermuse.com)
In my new MILC I never go under a v90 but guess you could get by with a v60.
V30 is the absolute minimum I will recommend.

Alan,When I ordered my X-T4, I made sure to order SD cards from the recommended list. These are also suitable for the X-T5 which replaced it. Similarly when I ordered the X100V, but cheaper ones as this camera cannot utilise the higher read/write speeds of the X-Ts.I wonder how many of us only use cards on that list.

Hi Ed,I bought a CFE card reader and guess what? no more issues !!!
HTH,
Ed
Yes, same here. No problems so far. You are more patient and methodical to test the real world speeds.Alan,When I ordered my X-T4, I made sure to order SD cards from the recommended list.

That's a longish time to clear the buffer.
I'm using the Lexar Gold cards 2000. I get 17 or 18 shots before it hits the buffer, and it takes:
Uncompressed RAW 8 seconds to clear the buffer,
Compressed RAW 4 seconds to clear the buffer.

Not true. Lexar Gold 300MB/s currently £149 for 128GB, £81 for 64GB from Amazon U.K. Maybe less via 3rd party or elsewhere. Paying for performance and reliability, not for a name. You are having problems with your less expensive ones. Your choice.It's not 10 bucks saved - I can't find the ones Fuji recommends.
[edit - not true, I can, but they are hundreds of pounds - which I think a lot for the name]

Based on spec rating, the green card (Select Plus) writes at 10mps; if you like Kingston - the red card (React Plus) rating would write at 260mps. Though I haven't used Kingston in recent years, they seem to be dependable and a good value - and you're pretty well assured that you won't get a counterfeit. The actual tested write speeds are listed in this chart:Thanks all for the comments. I've been using the 'slow' cards for about 400 shots and not had any issues.
I'll go and buy some faster cards. But I hope the 128Gb cards will be OK until I get some better ones.

Hi Tim,Hi Ed,I bought a CFE card reader and guess what? no more issues !!!
HTH,
Ed
What CFExpress reader did you buy? And does it read only CFExpress cards, or also UHS-II cards?
(The CFExpress reader which I bought is giving me some issues at least when using it with my MacBook; did not yet test it with Windows because that's currently not as relevant to my usage).
Cheers and thanks,
Thanks - I did look at that one but when I saw a 2-in-1 cardreader I thought I'd go for that... I do also have a good and fast, reliable UHS-II card reader already but it takes up a USB port and a CFExpress reader would also take up a port, so I thought that with a 2-in-1 reader it takes only a single port!Hi Tim,Hi Ed,I bought a CFE card reader and guess what? no more issues !!!

I got this one :

Unfortunately, it only reads CFE cards but I already have a backup drive with a reliable SD card reader for my backup UHS-II SDXC cards The SD slot in my MBP also works for SDXC.
HTH,

That’s good know. You saved yourself a few bob by having that chat. Truth to tell, I got the V90s because I thought it likely I would shoot some video… but I haven’t yetI had a lovely long chat with the Fuji rep at the open day. She was of the opinion that as long as I got UHS II cards at V60 or more, then they should be fine. The list from Fuji are just recommendations, not compulsory. If I want to do high speed video, then I should use V90 or CF-Express cards.
So, I have ordered some of these https://www.amazon.co.uk/gp/product/B074M64L1L and will test them out when they arrive.
