Prograde Digital Dual SD Slot Card Reader. It's Good BUT...

The Prograde Dual UHS-II Card Reader is able to transfer 2 UHS-II v90 cards simultaneously. Overall it is a good unit. However, there is expectation of what the unit can do due to the marketing and there is reality of what the unit actually does. In this case it does underperform.
Please note, I wrote writing with 2 t's lol
In this video I show you how it underperforms, my conversation with the Prograde company, and my recommendation on buying the Prograde Dual UHS-II Card Reader

Cool ! You are very good at explaining the Pros and Cons Nikos!! Laszlo Montreal;

[@NikosRentas]

Thanks bro. I appreciate the comment

[@pandoraefretum]

That magnet will damage your files, no ? I hate the idea of a magnet... can I remove it ? Also, I have a huge headache finding a fast SD UHS-II card reader..... I get 180 MBytes/s with a Lexar reader... I don't think I can find anything worthwhile that's faster. You are right to complain about mediocre gear... thanks for your concept of expectation... it is fair for us to expect. Great clip, Nikos.

[@NikosRentas]

Yeah I was concerned with it too but it will be fine. You could remove it or demagnetize it. Angelbird makes them without the magnet but is sent with a magnet sticker I believe. This is the best one I tested and did not test the Angelbird one. Again, most of these companies say it is a 10Gbps connection but in most cases it is shared between the two slots or it won't reach more than 7-8Gbps

[@tonygerassi1502]

Magnets will damage Spinning Hard Drives and floppy's. They write by using a head that magnetizes a bit for a 1 and un-magnetizes for a 0. SD Cards and SSD's do not use magnetized bits. They are a solid state system that turns the bit on (1) or off (0). That is also why they are much faster as there is no mechanical parts.

First thought was the same I assumed you were on USB 3.0 . Even still I am here because I got a Kinston dual UHS II card reader that does full speed on 1 card but with 2 it drops to 40MB/s and 150MB/s...

[@lyleyork7150]

Have you tested the OWC Atlas Dual CFexpress + SD Card Reader vs the ProGrade Dual reader. Great review of the latter btw. Thanks

[@NikosRentas]

Hey thanks. I didn't test the other two. I ended up gettign an R5 and bought thunderbird cards so got their reader to upgrade cards

[@CamLover]

Why the cable is USB 3.1 Gen 1?
And not the same? USB 3.2 Gen 2?
I placed an order a while ago this "ProGrade USB 3.2 Gen. 2.0"
But i don't know about the cable what USB 3.X Gen X it is. 😢

[@truckernige]

hi Nikos, i don’t know if you noticed but it says writting instead of writing… just saying… i’ve subbed and liked just because of that human error thing.. lol i like your style

[@NikosRentas]

lol thanks for pointing it out. My spelling can win awards bro lol. Totally missed that and I watched it over so many times haha. Thanks for the support!

[@truckingpix]

I have the same card reader and same SD card.... I get 42 MB/s when transfering video to my PC... Connected to a Z790 MB via USB 3.2 port, I9-13900K, 128GB DDR5; however, I get a message from Windows 11 that "Device can perform faster when connected to USB 3.0" WTF

[@weddings5649]

Writing has one "t"

[@NikosRentas]

Yeah I saw it after lol

[@mychalsimmons4177]

This product didnt work on my 2019 Macbook Pro SUPER WACK!!!! just get a 7 dollar card reader and SAVE YOUR DOE

[@NikosRentas]

I was doing some work with apple guys and it worked.. that being said someone else complained as well. Don't have apple so I can't test.

Prograde V90 256gbs vs Sony Tough V90 256gbs vs AngelBird V90 256gbs! Which is best? I need to buy two cards, which uhs ii is superior? Price doesn’t matter, which is superior

[@theoldschools]

If the price doesn''t matter i go with AngelBird v90 SDXC. Other good options is Sandisk V90 SDXC.
