Two more ways that you can tell the fake: 1) Look at the "S" at the start of the word "SanDisk" (in the video at 4:02). On the fake version the "S" is a different font/style to the authentic version - it has two little 'spikes' on each 'tail' of the 'S' shape. The fake card "S" looks different to the official SanDisk logo "S" (the official logo "S" has "smooth ends"). 2) All these memory cards come with a "RescuePro" software serial number. Download the "RescuePRO" software, and try to use the serial number to get an "activation code" for the software. If the RescuePRO serial number is a fake, the Rescue PRO website will give an error message. This will mean that the memory cards are fakes also. Further to this, I bought TWO of these fake cards off eBay at the same time and both packets had the SAME RescuePRO serial number inside. This is impossible for an authentic card, because the RescuePRO serials are meant to be "unique". Of course, when I tried the serial numbers on the RescuePRO activation procedure, it gave me an error message about the serial number. Lastly, my fake memory cards were selling for HALF the price of the authentic memory cards... I should have suspected!

It's funny you mention the yellow tab on the fake ones. I have 4 64GB cards. Two of them yellow & two of them grey tab. I've been using these "fake" cards regularly for years with my prosumer video equipment and never had a problem with write speeds. I do have 128GB cards on order from Amazon so I'll check them out once they arrive. Thanks for the helpful tips.

The number 10 on the far left card also stood out to me as not appearing typical font, it was much too thin compared to Sandisk.

As the two cards are placed either side at the front. The a on the large Sandisk logo is a different font on the fake.

Thanks for sharing this. I received a counterfeit one with the yellow lock tab - lots of issues trying to record video on a Sony camera and very slow buffer. I got it from an Amazon seller, luckily I can return it.

They probably appreciate your video. That should all be easy things to fix.

I got a fake 128GB extreme pro on Amazon and the seller was Sandisk.. it tested at 4GB

Notice the yellow lock on the fake full size SanDisk SD card while the real full size SanDisk has a grey lock.

if you have a good look at the both SDs, the fake one used different 'font face': 32Mb, 95Mb, U3, C10 and even the word: 'SanDisk'

I disagree on the part that Sandisk doesn't make sd card in Taiwan. The Sandisk Ultra 80mb/s I have is indeed from Taiwan that is bought from offline reseller

Does using a crappy sd card can lead to "freezing" or "busy...please wait" issues. My canon 750D suddenly won't take photos anymore bc every time I take a shot it will stuck in BUSY and I can't stop it unless removing the batt to reset. ☹️ but it sometimes works but then suddenly back to the issue 😩😭 HELP PLEASE im so broke to have it fixed to somebody else. Video works perfectly btw. Dunno why 😞 v1.0.0 firmware

I got a fake 125GB extreme pro card, but they both read true 125GB? If I just used them as overflow cards & just kept a real 32GB in my slot one would that change quality or buffer results ?

SanDisk is using Holograms now. You turn it side ways. You can see it has a mirror image that changes color. As for Ebay. Use PayPal. They will refund your money on the spot and go after the seller...

the micro card - i saw where it said u1 is smaller than the other micro card could that be one way to notice if is fake or not?

Visual clues not enough anymore. Grey tab and correct fonts etc, but i still ended up with 4 fakes paid at normal price from Amazon and another highly reputable Sandisk distributor. Back side said Made in Taiwan and Made in Japan, speed tests prove the fake UHS-II to be half the speed of the genuine UHS-I cards.

had the same problem its really enoying and so hard to spot the difference when buying only. think mine where purchased from the same seller.

I just bought 2 64gb extreme pro sd cards on amazon so going check them first!

The number 32 on the genuine is in bold text the fake isn't ?.

just got a card from amazon with a grey tab 128gb ext pro sd a7iii says can not format please enter a new card

Allegedly over 50% of Sandisk Cards on the market at any one time are FAKE, in fact it is more likely you will receive a fake than a real card, that is why you have to buy from a reputable source and then test.. even then not guaranteed - at one time certain reputable sellers were inadvertently selling fake cards.

Sławomir Gawroński, why I'm not suprised...

thanks

Extremely helpful! Thank you.

look at the letter 3 of 32 gb ..its different

The first second I saw the fake I found out that the "3" was in a different font.

It's too risky to photograph a wedding or any other paid gig on ebay sd cards, just buy them at costco or on dsale

Thank you.it was very helpful.

Please learn how to mix your audio. Do you have a super loud intro stinger and then at the same volume level on my hardware, you can’t hear you.

Super video. Thanks. I bought a FAKE sd card 128 gb extreme pro from seller - fast-track-shopping. Be careful.

On the fake they use a round 3 and on the real ones they have a angler top on the 3 !!

Hi Wish I knew about this before shooting loads thinking it’s there abs nothing Anyway, you might want to make a note of this discovery! I broke open the ad card in frustration and what I found is a mini SD seated in it. It was supposed to be a 128gb, but actually it was a 2gb mini SD. Therefore I was fooled into thinking it was working when I viewed the first bit of footage, but nothing else recorded after that

the card I bought has really great transfer speeds (up to 90 as promoted), isn't that in itself a good indicator that it's legit?

The 3 on the fake was a dead giveaway.

They can use a picture of the original card to fool you as well

It's so hard to know!

170 mb/s??

I've heard the square back is legit.

When i get a 64GB card i will test it straight away. I should get 1 hour 20 seconds of 4K video. if it passes the test does it mean its genuine.

You are 100% incorrect I just buy a Sandisk card from Best Buy 128GB Extreme Pro the back it said made in Taiwan and the side tap is grey color and it work fine!

do the fakes work?

There is a easy way to tell if it's fake go to ctmagazin.de and download h2testw !! It writes to the card and will give you the speed and also how big the card is !! Most fakes are only 8GB cards and MUCH slower than claimed !!

Why would you buy SD Cards on Ebay. 32GB SD card with 80mb/s range anywhere from $10-13 USD.

Thank God I got a real one, sheesh!

Get a better video camera macro lens that helps you to focus easily on close ups. The light was switched on only halfway into the video. Why ? The FONT of the number "3" is very different in the Fake SD card. The "3" in the real card is Montserrat font with a straight top line.

just don't shop on eBay, unless you are buying a pencil

So I bought a card NOT from eBay but from an actual store. Does that mean I'm good?

surely you need to test the speeds??? this would be a more accurate measure ? I would suggest thought that the real speed will not show as you will be limited by the speed of the card reader hooked to the computer?

That's the main reason why I avoid ebay.On amazon most sellers and products are verified, refunds can be made, and items investigated by the company. On ebay anyone can sell anything, real or fake.I would contact trading standards over this seller, they're obviously making a lot of money and ripping off other people. Who knows what the police may find, perhaps more criminal activity. Justice is always nice to serve.

Waiting for you to get round to actually pointing out the differences was like waiting for paint to dry. Why couldn't you just say; the fake ones got a yellow switch and the genuine grey. That's far simpler isn't it?

The CE branding on Chinese products are not the same as the european quality stadard, In China CE just means China Export

Good info, poor video

Use h2testw, thank me later...
