Your Card Reader is TOO SLOW (SanDisk PRO-READER vs. ProGrade CF Express Reader)

I would love to see a test where a strong fan is blowing on the ProGrade to get some sort of indication if heat might be responsible for the slow down.

may be cache on a mac. what you need to do is create two 256gb with different content of file for each reader then try to transfer again.

Nice Test Steven - Thanks

But we need you to use a type a!

I almost bought the wrong reader because of you! You didn’t tell us wtf is a cfexpress card my camera takes Dd cards not this crap.

so what about sandisk card? are they reliable? cfexpress are expensive so better to make a deeper research

i would proffer that the difference may be down to SanDisk QuickFlow technology, which i know that that reader has, and IF your card is also QuickFlow enabled then that will likely be why.

Is there any readers you recommend for usb 3.0 ? My iMac and MacBook Air do not have usb c unfortunately

Mac doesn't even show the transfer speed when you transfer files 🤯

i have this sandisk reader and the fast Angelbird sx160 pro but only have 600MB/s. I will buy the prograde tb3 reader

Just ordered the 2 versions of the Sandisk Pro based on the strength of this review. The other model has the same matching cabinet design and dimensions and reads CF Cards type one: SD Cards UHS type ii and microSD UHS type ii cards: reader has 3 separate slots for the above. Type ii cards are backwards compatible which means type 1 cards can be read (and used) as well. These look like $$ well spent. 😊😊😊

Terrific review. Hope you can review a iPad Pro 12.9 (2022) w/magic keyboard + pen sometime soon. Would love to hear your evaluation of these…Many thanks for this incisive review. 🙏😊

Thank you for that test!

Which model prograde reader did you use ? was it the dual slot usb 3.2 gen 2 ( 10Gbps) ? or ?

Will the sandisk reader work with Angelbird cards? I've heard that some readers have issues with different brands. Will read one brand but won't read another one.

You think the cf express card type B there wouldn't be such a massive time issue.

How about just plug the usb cable from your camera to your laptop and transfer that way with the card inside your camera?

this video came up on YT when I searched "cfexpress type b reader" it was one of the top 3 shown so I wanted to leave that info here. Nice video, I just got the R5 (2 days ago) and I'm loving it as my EOSRP upgrade. I also wanted to say that I bought a CHEAP reader also on Amazon- returning tomorrow- and I might go for this one now. Nice videos man, keep them up!

Will the San Disk CF Express Pro-Reader work with SD cards?

Shit!
I am using that Prograde reader!
I hope any firmware update for it.

Just found your channel! And its came at the best time possible, the sandisk professional does the job i need, to offload cards fast and not heat up the card like its in an oven! Your review has definitly made me happy in my purchase with a reader for my sandisk 512gb cfexpress card for my R5! Appectie it dude :)

It's reading cfexpress A or B ? Or both of them.

Anyone else notice that Strymon folder? 👀 Cool idea for a video, Steven!

Would be curious to see the results between the ProGrade Thunderbolt 3 Reader and the Sandisk Pro. ProGrade offers 2 types of CFExpress readers, but the TB3 one is almost always sold out.

I want more Future Steven in my life please

Here for techy short videos! Nerd alert

I just thought my CFexpress was hot after transfer because all the fire I shot on that card.
