How customer reviews and ratings work

Customer Reviews, including Product Star Ratings help customers to learn more about the product and decide whether it is the right product for them.

To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyzed reviews to verify trustworthiness.

4.0 out of 5 starsGreat value and works as advertised.
Reviewed in the United States 🇺🇸 on May 1, 2023
The Amazon Basics microSDXC Memory Card with Full Size Adapter, A2, U3, Read Speed up to 100 MB/s, 64 GB - Pack of 2 is a great product that offers a lot of value for its price. The pack of two memory cards provides ample storage space for your photos, videos, and other files, and the full-size adapter makes it easy to transfer data to and from your computer.

One of the standout features of this product is its fast read speed of up to 100 MB/s. This allows you to quickly transfer large files, such as HD videos or high-resolution photos, without experiencing any lag or delays. The A2 and U3 rating also means that the memory card is designed for high-performance applications, such as gaming and video recording.

The full-size adapter is also a convenient feature, as it allows you to use the memory card in devices that require a full-size SD card, such as a camera or laptop. This versatility makes the Amazon Basics microSDXC Memory Card with Full Size Adapter a great choice for anyone who needs to transfer data between different devices.

Additionally, the memory cards are compatible with a wide range of devices, including smartphones, tablets, cameras, and more. This makes them a great choice for anyone looking for a versatile and reliable storage solution.

One potential drawback of this product is that it may not be as durable as some other memory cards on the market. While it's unlikely to fail, it may not hold up as well under extreme conditions, such as exposure to water or extreme temperatures.

Overall, the Amazon Basics microSDXC Memory Card with Full Size Adapter, A2, U3, Read Speed up to 100 MB/s, 64 GB - Pack of 2 is an excellent product that offers fast read speeds, ample storage space, and a convenient full-size adapter. It's compatible with a wide range of devices and provides great value for its price. However, it may not be as durable as some other memory cards, which is something to consider if you need a memory card for use in extreme conditions.

5.0 out of 5 stars To be honest I was skeptical because of the "brand"
Reviewed in the United States 🇺🇸 on May 10, 2023
Capacity: 128GBVerified Purchase
I've only had it for a couple days but it works great in my phone

Which is a Samsung Galaxy A03S and as far as I know he's going to be very picky with what sd cards it decides to work with

the truth of the matter is 90% of SD cards are made in you know other countries a lot in China and Taiwan

To be honest skeptical with anything that has the Amazon brand or basics or whatever

It can be very hit and miss

That doesn't mean anything no different than going to Walmart and getting you know ONN technically in Walmart brand but that doesn't mean anything

It's all dependent on how much you said company wants to you know spend on said quality

I'm very happy that has a warrant

5.0 out of 5 stars Works well with RunCam
Reviewed in the United States 🇺🇸 on May 14, 2023
Capacity: 128GBVerified Purchase
RunCam accepts a maximum of 128GB exfat or fat32. Works well with exfat, no reformatting required. You'll lose 16GB for secondary OS partition if formatted in Windows ending up with about 117GB. Still a huge amount for recording HD video. Runcam takes about 500MB per minute for 2K video for a total record time of about an hour. If you drop the settings down to 1080p then you get about 2 hours of record time. Card works well, no idea about longevity as I just started using it. This will go in an RC car so it will take some physical abuse.

I bought this for my new kindle that is strictly audio books and graphic novels/comics. So far its worked pretty good but it has only been a few months. If anything my only complaint is that I had to do a set up with my kindle for this cause I'm not good with technology

5.0 out of 5 stars 256gb Amazon basic vs 256gb SanDisk Extreme
Reviewed in the United States 🇺🇸 on January 2, 2023
Capacity: 256GBVerified Purchase
I am reviewing and comparing two different memory cards, the Amazon basics 256gb and the SanDisk Extreme 256gb card.

First is price, the Amazon basics is a several dollars less than the SanDisk (at this moment 23.72 vs 36.99). Currently Amazon says there is a newer version of the SanDisk for 24.85, however I have not purchased or tested the newer version.

The two cards:
"SanDisk 256GB Extreme microSDXC UHS-I Memory Card with Adapter - Up to 160MB/s, C10, U3, V30, 4K, A2, Micro SD - SDSQXA1-256G-GN6MA"
"Amazon Basics microSDXC Memory Card with Full Size Adapter, A2, U3, Read Speed up to 100 MB/s, 256 GB"

Tested using:
CrystalDiskMark 5.5.0 x64.
Computer is a 4 year old "NUC8i7HVK" running Windows 10, and it has a built in SD card reader (Intel calls it "SDXC with UHS-I support"). This interface is what I call "SD reader" in the accompanying screen captures.
I also tested using a SanDisk USB 3 adapter "SanDisk MobileMate USB 3.0 microSD Card Reader- SDDR-B531-GN6NN". This interface is what I call USB3 in the accompanying screen captures.

First, I noticed a UK review where the reviewer noted the Amazon basics card seems to be missing 5 gigabytes of storage even when the (confusing) translation from computer storage gigabytes (1024 x 1024 x 1024 = 1,073,741,824 bytes vs 1000 x 1000 x 1000 = 1,000,000,000 bytes) vs "we sell storage" gigabytes. You will notice CrystalDiskMark reports the Amazon basic card as 233GiB versus the 238GiB of the SanDisk, so he is very correct. I have no clue why the discrepancy, but it is slightly smaller than it should be.

Second, to get the real read/write speed of the SanDisk card, you will notice I had to use the SanDisk USB 3 adapter. Using the built in SD card reader, both cards were very close to identical results.
Using the SanDisk USB 3 adapter, I did manage to exceed the ratings for the SanDisk card (up to 160 MB/s read, and up to 90 MB/s write) giving 169 read and 105 write. The Amazon basic card did have a slight change using the SanDisk adapter, but really not significant.

Both cards were close enough to their claimed specs to not worry about it, however it should be noted that you need the SanDisk adapter to actually get the much higher speeds of the SanDisk.
I will be using the Amazon basic card to store children's movies for my granddaughter to play on her new Kindle, it is plenty fast enough reading to do full HD movies.

Note that both cards were brand new when tested and had never had anything written or read from them prior to the test. The Amazon basic seems a good value and is certainly adequate for normal use in a cell phone or laptop. The SanDisk would really shine if you used the adapter to move lots of larger files to it.

4.0 out of 5 stars this one works
Reviewed in the United States 🇺🇸 on April 9, 2023
Capacity: 1TBVerified Purchase
This product worked. I ordered 2 USB sticks prior to this and both were in the 30 to 35 dollar range both were basically scam USB sticks. I've found 1 TB USB sticks below 100 dollars are mostly junk some aren't but they're hard to find. This was a Micro SDX card with Amazons name on it and wasn't the cheapest but it worked so that made it worth the money. I'm a little disappointed that Amazon allows these fake drives to be sold on their site. You can figure anything that says 1,2 TB USB drives below 70 dollars are all going to be some hacked version with some type compression or no memory chips just the driver chips. Amazon should clean these vendors up and get rid of the memory sticks that don't work and there's a lot of them.

No dislikes. Got it to see around the front of my house. Took a little time to get it to connect to my WiFi. It had to be 2.4 for it to work. After I got that taken care of it wasn't a long time for set up. Great product and would buy again. It's a little pricey though. I would buy again.

4.0 out of 5 stars 1tb advertised, 928 actual
Reviewed in the United States 🇺🇸 on March 29, 2023
Capacity: 1TBVerified Purchase
Not going to return it or anything, but this is advertised as being a 1tb card, but the actual storage capacity when plugged in is 928gb I am short 72 full gigabytes of storage. may as well advertise this as a 900gb micro sd card and give users a pleasant surprise when they find 28 extra gigs of space rather than finding you are short 72 gigs of space. really hits differently. The write speed I was seeing went as high as 28 MB/s and as low as 11 MB/s just moving a bundle of zip files from my main SSD to the Micro SD, now that could be caused by the card slot on my pc, but I doubt it. Not as large as advertised, and not as fast, but still cheaper than other options out there, and from Amazon so it isn't likely to die on you at least. So take that information as you will, I am glad to have 900 gigs of extra space, a little miffed about the 72 missing gigs, but I will keep it
