A serious SD card for the prosumer photographers/videographers. E.g. Canon EOS R, LUMIX GH5, S1, or Fujifilm X-T3.
Others (e.g. Sony A7 series, Nikon Z6) would be happy with the SanDisk SD Card 64GB SDXC Extreme Pro 170MB/s C10 V30 UHS-I 4K UHD, $21.89 is the lowest price I have ever seen.

Thanks for raising this. I will update my description. It will be ideal for the Canon EOS R, LUMIX GH5, S1 and their ilks. I believe Fujifilm X-T3 with 400mbps is also a candidate.
Sony A7 series users would be happy with V30 (Sandisk Extreme Pro link above) as their 4K bit rates are 100mbps.
I'm almost certain that fast cameras like the X-T3 and A7III will benefit from these UHS-II cards when shooting continuous high. If you just hold the shutter down you'll still hit the wall eventually, but you'll get more shots and the buffer will clear much faster for the next burst.
Whether that's of any real world significance to an enthusiast is another thing however. Certainly there are still plenty of cameras in use today that will no benefit from these faster cards.
very good point to raise, i haven't bought a new rig in a while and tbh i'm not 100% aware of the burst limits on the current pro tier. i guess to play it safe members with those level of bodies should buy this one, its certainly the fastest in the offer ane well priced for what it is (only v60 card i saw when i made my haul), it comes back to a case of if its needed rather than its value here which is excellent. if members with those level of bodies wanted to to see if they could save a buck they would have to do the math on the max file size per image and max burst number for their rig to see if they can saturate v30.
what data rate is needed including handshaking for doing 24 mp raw at 10 fps ? …
again depends on the camera - different raw formats so 24mp raw isn't always the same filesize. that and the camera will have a memory buffer of some sort that will take up some of the slack. Generally uncompressed 24MP Raw is 48MB and compressed is 24MB, then some more overhead for a jpg image if you do jpg+RAW and handshaking, so thats 240MBps-480MBps less whatever the memory buffer in the camera can do. Might have to google your camera specs to see what maximums people have hit as the contribution of the buffer will be tough to calculate. The other issue is that depending on how the V standard is tested (generally they use video to characterise a sustained write), the sustained write speed might not be the killer spec.
personally i'm running an old 600d and found that i couldn't notice a difference between a U3 card and my friends extreme pro card (not v60 certed though), but i also do very litle burst.
Am I the only one that always gets confused by the name of the card and thinks it's 1667 cards?
the "numberX" system is super old and dumb and relates back to the speed of the old school cdrom (150kbps) but is measured in MBps, so this card is 1667MBps*150kbps = ~250MBps. Its a needlessly confusing system and only refers to the max read speed.
Generally people care about sustained writes.
The V system stands for Video and we commonly have V60, V30 and less commonly V90, where the number is minimum sustained write speed in MBps.
There is also the U system that has U1 and U3 ratings where the number x 10 is minimum sustained write speed in MBps (so U3 is equivalent to V30).
We also have the old class system - previously class 1-10, nowadays you'll only see class 10 cards as class ten is equivalent to U1.
Lastly there is the new A system - A1 (best) and A2 - referring not to sustained write but to random read and write, though this only matters for devices that are running applications from the card i.e. phones and tablets.
Then there is UHSI and UHSII which are hardware revisions - a card requiring UHSII to reach its full speed can't do so unless the device it is used in supports UHSII.
Thanks. Got SanDisk.
worth mentioning that the 170MB/a cards are no faster than the 95MB/s cards unless you're reading/copying from them with a special card reader from SanDisk.
yes good to mention. 104MBps is the max speed attainable on UHSI, you will need a device supporting UHSII (card reader, camera etc) to get the maximum performance. for this lexar card though it is a special use case in being v60 certified, meaning that the minimum sustained write speed is 60MBps, i.e. you should get 60 out of it all day every day in a camera that can write at that speed or any usb 2 card reader (as long as the destination drive can do 60 i.e. ssd). the 95 cards often have a maximum write speed of 45, 60, 90MBps depending, the sustained write speed even for the 90 cards will often be below 60.
So much chatter about whether this card is worthwhile. Fact is, it's $30. The cost is insignificant: If you're in this thread you have cameras and lenses worth thousands. Give it a go.
The only question I'd be asking is whether Chinese lexar is reliable. Surely that's more important.
Note this will only be useful for those with a DSLR/ML or VC that is recording high bitrate 4K (above 240Mbps or 30MBps), otherwise a cheaper V30/U3 card will do the job. I'm not aware of any DSLR/ML that can max out V30/U3 for sustained burst images but I may be wrong.
