Sandisk 64GB Extreme PRO UHS-I SDXC Memory Card - 170MB/s version (Free shipping over $49)
$25.86 - https://www.bhphotovideo.com/c/pr..._card.html

Also available:
128GB - $46.68 - https://www.bhphotovideo.com/c/pr..._card.html

Must buy two to get free shipping or find another product to buy with it.

These appear to be a SanDisk new release according to B&H. According to the specs, these will read up to 170MB/s and write at 90MB/s. By comparison, the older popular version of the Extreme PRO cards have a read speed of 95MB/s and write at 90MB/s. Both have a minimum write speed of 30MB/s which is enough for 4K video.

For those who don't know, 30MB/s or megabytes per second is different from Megabits per second (Mbps or Mb/s). You'll see that some cameras will shoot 60mbps and 100mbps and sometimes 200mbps. 30MB/s = 240Mbps (Mb/s)

Max write speed is still 90 MB/s though. And that is what matters the most.

Not necessarily. I'm the type of photographer that doesn't spray and pray. But I am the type that will get a few hundred to a thousand photos from an event or a day of shooting. So faster than 90-95 isn't necessarily useful for me. Also, i think many professional photographers wouldn't max out their buffers for fear of having to sort through that mess during post processing.

A faster read speed would significantly cut my upload times to my computer though. Each has its own advantage.

Edit: i never said that faster write speeds was not beneficial. Yes I have maxed out my buffer before - during a wedding during the flower and garter toss, but other than those times, I don't do it and neither do other professionals. Everyone likes the option of larger buffers and quick clearing of it with faster cards.

The point of my comment was to say write speeds are not the ONLY important speed for everyone, especially when you're writing at 90 mbs. This is near the fastest UHS I can write. I personally would rather give up 5 mbs for 170mbs read speeds.

I guess when your opinion differs from someone else's, you get seen as "unhelpful".

Worth it to go with UHS-3 for future proofing? I already have Samsung 90MBps read/write and older Sandisk Extreme Pro, this doesn't seem like a big improvement.

Edit: what's with the downvotes for asking a genuine question?

Faster read speed isn't going to be substantial, it just means spending an extra few minutes grabbing coffee. Unless you are doing a sales sit down with a customer immediately afterwards and need to upload, batch edit, and organize some samples in under an hour.. you're fine.

Having the presence of mind to be able to utilize your buffer in a key moment or two is where write speed matters. No one shoots constantly. If anyone does, it's because something unique and hard to replicate is happening and you aren't sure which of 20 shots will be the perfect one.

Yes. This is true for your situation. Not so for wild life, especially BIF work. Faster is better for that kind of photography. And CF can not be beat. But a capable backup SD card is necessary.

This isn't an improvement. This is a cheap fast card. Get some to put places for emergencies like in the car and in bag so if you forget your SD, you have these pretty good cards to use.

UHS-3 (the U3 you see on cards) just means minimum 30MB/s sequential write. Even if you had a UHS-1 (U1, or minimum 10MB/s sequential write) and the manufacturer had a guarantee of minimum 90MB/s sequential write, it wouldn't make a difference (I've seen both Samsung and SanDisk cards that are U1 and have stated 90MB/s sequential writes on their cards).

Your SanDisk and Samsumg already do 90MB/s sequential write so a U1 vs U3 card makes no difference.

The only thing that's next are UHS-II bus cards (NOT to be confused with UHS-1 (U1) or UHS-3 (U3).

Note that most of the U1/U3 cards you see nowadays have a capitalized I next to it. This signifies UHS-I bus speed, with theoretical max of ~104MB/s. UHS-II (indicated by capitalized II) cards will have a theoerical max of 312MB/s. Expect newer cards, cameras, card readers to leverage these speeds.

Example: SanDisk UHS-II U3 (lol) card, with 300MB/s read and 260MB/s write. - https://www.amazon.com/SanDisk-SD...B01MFCQVLB. Funny that they still put the U3 marker (minimum 30MB/s sequential write) when the card itself advertises 260MB/s sequential write instead laugh out loudlaugh out loud
Pair it with this SanDisk USB-C reader, rated up to 500MB/s - https://www.amazon.com/SanDisk-Ex...B07B1HQPV3

I love when people write silly things like "most professional photographers....." blanket statements, like they are the only professional type out there. Many different types of shooters will benefit from these cards, including wedding photographers. Wildlife, sports, weddings - hell, even child photographers can benefit from fast buffers that write quickly. And of course, video.
If you need decent cards, buy them. Don't worry what anyone else uses them for, if they fit you, do it.

Thanks. that clears it up. Faster read may be worth it if I needed to scroll through the images very quickly. So far that hasn't been a problem. I'll wait for the 300MB/s cards to drop significantly before purchasing.
