Excellent cards

Before I get into the testing, let me point to some of the more obvious physical aspects of a fake microSD card vs. a genuine one.1

Time will tell how resilient these cards are but the cards I just replaced were older SanDisk units and they withstood the test of time.

I love this SD Card

Really nice card at a really good price, quick ship

These cards have survived many many crashes

Otherwise, you may think you got a bad or counterfeit card

based on my experience this cards will work with DJI product

Bought from CWP Online and it is a genuine card.

This card solved my issue of jerky videos with frame drops on my apeman action camera

Both cards work great in my Panasonic fz80, Sony hx80, and GoPro 8.

Reliable card, I never have problems with it

This card does not work well with gopro hero 6 black

Great super fast Mini Sd card, only card I have I can use on my Insta 360 OneX

My guess is these were known faulty cards and they are trying to pass them off as "hooking up" the customers with more memory space

Nice Memory Card

This is supposed to be one of the Best memory cards out there

Packaging was FLATTENED to the point where the adapter card is entirely unusable upon arrival

I have purchased from this supplier on numerous occasions and haven't gotten a fake card, EVER.p.s

I don’t think any brand can compete Sandisk fast cards, lifetime, no error cards ever

The card came in retail packaging, the printing was crisp on both the packaging and the card

I can say that these cards are awesome and you just can not beat them for reliability.

Great and extremely fast memory card, you will notice a difference when using your camera or cell phone when using this product

+ Adapter, SDSQXCY-128G-GN6MA are the best micro cards with the fastest speeds I have used so far

Card is completely useless

I used this SD card for 2 days and it died already!

great card, I can take 4 hours of 4K video on my goPro Black!!

I understand that there are a fair amount of counterfeit Sandisk cards on Amazon, but since these particular cards weren't available locally I decided to gamble and test them myself

Time will tell about its durability, but it is by far the fastest SD card I've used for a laptop backup

Best memory card that i both

Original SD card,NOT fake

Card failed untouched in my phone after 5 months

Very fast micro card that is needed for 4k video.

This card is faster than the other 3 brands I tried out.

This card is great

Got it to work with the new insta360 I got, great card so far so good!

Update: Like it says below I received the wrong card at

I compared the speed of this to the speed of a cheap $5 32Gb generic card and somehow the generic card was 10mbps faster

Pro mini card works great in the DJI Mini 2, so I will recommend it.

but Im convinced that this card is genuine

Great MicroSD card

Very good card for the Mavic 2, super reliable and large capacity

Works extremely well, but later learned this card is way faster than my camera's capabilities

.... however the card is faulty and does not work correctly

Sandisk is my favorite SD card brand and the Extreme

Overall it's probably one of the better cards out there, it works on the Nintendo switch no issues at all, but honestly, it probably would've been better to go for the Sandisk ultra since you get better value and save a bit more money if you're only looking to get it for the switch

Though despite the loss of time and related aggravation, this is a good card and worth the price

I compared the speed of this to the speed of a cheap $5 32Gb generic card and somehow the generic card was 10mbps faster

The card and adapter were also both very flimsy and did not connect to each other or go into the computer smoothly at all

I have been using this card for a couple of months and it has not disappointed me.

Decided I needed to upgrade to the 128GB one, but after reading the several reviews about fake microSD cards, I download a speed tester and tested my older 64GB one, and then this one right out of the box

/s].If you use the correct card reader (USB3 type), one capable of handling higher speeds, you will get the results that the card is advertising

This card - the SanDisk Extreme Pro UHS-1 U3 A2 V30 works perfectly

Fake cards are rampant for this item, and there are too many reported fakes (I would imagine since most people don't realize how slow or fast their cards are, this number is likely 10 - 100 times more than the number of reviewed fakes).

This SD card is worth every penny seriously

These tools are not great, though they will confirm if you got a genuine card and, they will set “real” expectations for your card’s Read and Write capabilities

If it's not that big of a deal, go with the cheaper card

This card solved the problem I was having with my Insta360 One X camera.

Great storage card..good value for capacity

This is a great micro sd card to use

I ultimately started trying things like tweezers and prying which resulted in damaging the card and ultimately destroying the adapter at the end in order to get the micros card out

This microSD card is amazingly fast

I received a fake card (256gb)

and now I'm screwed this weekend unless the 2nd one I ordered with next day shipping turns out to be the right card

Just make sure you're getting the right card

Unfortunately the card still failed the test again and had to be returned

There are plenty of fake SD cards being sold including from large online retailers such as this one

I hunted around for days trying to find a reasonably-priced Sandisk Extreme Pro memory card with lots of storage

Every single time someone asks what the best SD card is for their drone, I show them this one

So far card works and

Great little memory card.

Perfect card for 4k filming, one of my all time favorite cards

After several time seeking a good and original SD card I found this one and after buying it, I was expecting to receive it and open the box in order to see if this memory card would be original or fake but now I can say, it is completely original, not a fake, the rate of writing speed is about 75 - 90 Mb per second, depending of what kind of card reader speed is, but it is completely original, writes very fast, and reads very fast too.

I, like the rest of you, worry about getting a fake SD card

This card does not work well with gopro hero 6 black

The drones require a fairly fast uSD card, and this has worked perfectly.

This card is a fake.

Reliable card, I never have problems with it

Excellent card

If you use any of the cheap card sleeves or USB adapters it will not give you proper speeds

After testing with H2testw which is a free utility that will write to all of the available card as well as test the read/write speeds I determined that these were in fact legit cards

Great card.

Great card with great price

.... however the card is faulty and does not work correctly

I will update when I see if I get the slow SD card warning in the Mavic air on 4k

So with that being said it's not that bad other than being a little upset that the card isn't genuine.

Not really sure that these are genuine SD card

is a little faster, for that alone this card is perfect

Really fast and reliable sd card

i’m also just as happy that i don’t have to look anymore for accurate microSD cards.

The capacity test is more revealing than the speed test since bogus cards have had their microcontrollers reprogrammed to report larger capacities than what they are capable of

Fantastic SD cards, huge storage space was perfect on our Rarotongan trip

, this is a great SD card, it is extremely fast in both read and write, but for the money, the Samsung

The SanDisk Extreme Pro is one of the best microSD cards you can currently buy

Extreme Pro is the fastest card on the market.

This card works great in my GoPro 7 Black.

Long story short, I was able to use data recovery software to get most - but alas not all - of my media back, via a raw disk scan that took many hours (this card is a bit slow, to boot), and it cost me $150 for software to do it

Excellent memory cards - all videos are recorded well and nothing lost - will but again.

Out of the blue, after about a year, the card corrupted.

The Hero 9 can record 5k video and this card plays 5k video back on the Hero 9 just fine, but I've only recorded in 5k once just to try it out

The only thing I was a bit sad about was that it does not come with a plastic case like other MicroSD cards do.

Legit card, fast, great for my note 9

When I used one of the cheap card readers, the maximum speed was only about 25 MB/s for each card.

I bought this after I noticed my daughter's fire tablet was sluggish after putting in a cheap, slow SD card

Fast reliable cards.

With so many "fake" sd cards being sold on the internet it pays to be cautious and test all sd cards

Fast card

Suggestion, get the highest capacity you can afford - this card is lightning quick.

Good card and hi capabilities

Now, as I see it, the real issue here is that SanDisk includes a cheap, flat card reader, which is not compatible with any device made today

Good SD card.

These days, you need a fast card for 4K and higher video recording, and this delivers rated speeds with no problem

This is a great sd card for the galaxy s20fe faster than my old card for sure

Great card for my GoPro and extra storage for my iPad

In Windows/Mac world, that means it's as fast as or faster than magnetic hard drives for me.

Works as

The other two manufacturers boast much faster read and write times for their microSDXC performance, yet this card remains my fastest R/W performer
