Worth Money
Super easy to order, the memory is extensive so it is ideal. I used this for my daughter’s tablet for her games, it’s does exactly what it does on the tin. I haven’t used it for anything other than storage though. Arrived super quick too!
Good SD card
Very good quality SD card using it on my next base for 22 GW dash Cam have not had any issues as certain SD cards such as SanDisk I have issues with Nextbase dash cams
Does what it says for a good price.
Just want a SD card that works for a decent price? This will be it.
Tested on Steam Deck and Nintendo Switch, no issues thus far.
Quality wise feels exactly like anyone other SD card on the market.
Packaging was basically plain, with tons of small text, I know it’s cheap but maybe a photo of the product would be nice.
Excellent, high quality
Perfect. Very good price, very good product. Tried a few SD cards before this one that didn’t work! This solved the problem, a product you can trust at an incredible price!
Bargain storage
Not the fastest of cards but you can’t grumble at this price, perfectly capable just a bit slow on the write side of things, it’s pretty good with large videos or archives like rars or zips but folders with numerous smaller files in big it down..
A card that is what it says
After finding out that two cheaper micro sd cards were not the advertised capacity ( a 1tb card that was 30gb and a 256gb that was measured at 26gb both bought from Amazon) the 1tb card was bought for use in a Nintendo switch, it failed after I bought a few digital games and the download failed, the 256gb card was bought for a camera but never used, this had the same symptoms, download failed. I looked again for another card this time an Amazon branded 500gb card. This time the card is the capacity stated everything downloaded without a problem. I did get a refund for the 1tb card but I had the other too long. Be very careful buying ‘ bargain ‘ micro SD cards, you may not get what you pay for. I downloaded a Windows program to check the cards ,do a Google search.
If the card starts to fail I will update this review
I am incredibly impressed with the Amazon Basics Micro SDXC 512GB with SD Adapter! If you’re looking for reliable storage that delivers exceptional performance at a great value, look no further.
Firstly, the storage capacity of 512GB is perfect for storing a vast amount of photos, videos, music, and more. It provides ample space for all my digital needs, whether it’s capturing high-resolution photos on my camera or storing my favorite movies for on-the-go entertainment.
The read speed of up to 100 MB/s ensures quick access to my files, making file transfers and loading times swift and efficient. This is particularly handy when I’m transferring large files or accessing data-intensive applications on my devices.
The inclusion of the SD adapter is a thoughtful addition. It allows me to use the micro SD card with a wide range of devices, from cameras and laptops to tablets and gaming consoles, offering versatility without compromising on performance.
The build quality is solid, and the card feels durable and well-made. It’s also A2 and U3 rated, which means it meets the highest standards for app performance and video recording, making it ideal for demanding tasks like 4K video recording or running apps directly from the card.
Overall, the Amazon Basics Micro SDXC 512GB with SD Adapter has exceeded my expectations. It’s reliable, fast, and offers tremendous value for money. Whether you’re a professional photographer, videographer, or simply need extra storage for your devices, this micro SD card is a fantastic choice.
Grea
I have the camera eos 2000D and it works great with it, I can now access and saved photos on this camera! It fits perfectly and it’s really easy to use.
Works fine in my 4K drone
Bought this as I needed an SD card for my new drone. Happy to say it worked absolutely fine and the footage was captured without any stuttering or jerkiness. Another great Amazon Basics product.
Great Value
After doing a lot of research about read and write transfer speeds, I decided to take a chance on these. Bought both 256 and 128GB capacities. Performance has been good on my action cameras and 360 cameras so far.
Bought for my Samsung Galaxy Tablet and reviewed as if I know nothing about storage…
+ Much cheaper than similar products.
+ Easy to fit. Just open the drawer on your phone or tablet, slot it in and it’s recognised straight away.
+ Tons of storage on the 256 gb. You’ll struggle to fill it. More than enough.
+ Easy to transfer files to a new device. If you transfer everything onto the SD Card you can just insert it into another device to access all your files.
– Takes some setting up on your device (Saumsung). Things will save by default to your internal device storage so you will need to change your settings in various apps. If you wish to clean up files already on your device, you’ll need to use your devices built in file manager to transfer them over.
It’s pretty simple stuff but if you’re not used to it you’ll need to learn it.
Dash cam - suitable size with adapte
Purchased for dash cam that required 128mb micro. As an amazon basic product this seems comparable with branded products purchased in the past. Working well and able to pull data no problems. Handy that it comes with adapter. Will be my go to purchase if we need another in time to come given price and quality.
256GB Astonishing Value for Money
I needed a 256GB microSD card for a new camera purchased. Looking around the prices are all over the place. This Amazon Basics had the right specs that I was looking for, and was half the price of the cheapest other branded microSD cards out there.
We all know that there are SD cards out there that are fake and not as advertised in terms of storage capacity and/or performance. But no such fears about Amazon Basics which I have found to consistently be as advertised.
And so it was with these (I ordered two for the price of the cheapest others). On receipt I tested them for Speed and Capacity using software tools. The cards were what they said they were.
Once again, Amazon Basics doing what it says on the label. Bravo. Highly recommended.
It works bu
It works in our Amazons iPad but it often asks us to reinstall the card it’s not a big thing as we just have to get it out the slot and put back in but that’s why I gave 4 stars
Great Value
I recently bought the Amazon Basics MicroSDXC 256GB card and am genuinely impressed. It offers excellent value for the money, providing ample storage space for all my needs at a fraction of the cost of other brands. The card works flawlessly, with fast read and write speeds that keep up with my demanding applications and media storage. It’s been a reliable addition to my gadgets, enhancing my storage without breaking the bank. Highly recommended for anyone looking for an affordable, high-capacity microSD card that doesn’t compromise on performance.
Finally genuine product!
I’ve tried to purchase an sd card for a camera and I did not expect it to be such a difficult task. I purchased my first sd card from a business that had good reviews and unfortunately it was fake, the second one never arrived. So I thought I will go with Amazon own product and it’s arrived quickly, properly packaged and it wasn’t fake so everything worked straight away. Thank you Amazon for providing with a product that can be trusted and at a good price!
Brilliant produc
This has been a great purchase. Used this for external storage for a games console as the internal hard drive had been maxed out. Great price and recommended this for other people requiring external storage.
Superb value
Bought for nintendo switch to download games. Surprised at how much capacity could get for the money. Slotted in and worked straight away so no complaints and provides so much storage, it’ll likely be years before it’s full.
Works well in my Dashcam
Works well in my Dashcam, all OK, formats OK so all good.
The previous card I purchased through amazon, but from a third part supplier turned out to be useless, and failed after 6 months, turns out I think it was formatted to make it seem like it had a greater storage than it actua had, and the seller has changed site or name, no reply when I sent messages. So I will stick with Amazons own memory cards from now, ordering direct from amazon is poss a better bet.
I purchased this for my handheld game console. I already had one that came with pre-loaded games when I bought my console, but I wasn’t confident in its quality or reliability since it was from an unknown Chinese brand. I transferred everything to this new one, and it’s working great. With its generous 512GB capacity, I could add more of my own games and still have plenty of space. It’s performing well in my console, and the price is reasonable.
Great SD card
Great SD card that you could use for computer, phone or tablet. Great price and works pretty much as soon as you install it. I use it in my tablet to great effect.
Does what it says on the tin.
It does exactly what it says it does. It’s a micro SD card with a capacity of 256 GB. It does come with an adaptor to turn it into a normal sized SD cars, which is a nice bonus.
Its a good un!
Like batteries, there is always a need for another one, mainly because I can’t remember where I left the last one? This time, we have a 1-day turnaround, and now I need to fill it with 128 GB of songs. Come back to me in about 17 years, I suspect?
Good product and fast delivery!
If you want to extend your memory on your tablet or want to store video,music or basically any file on your Laptop, then don’t waste loads of money on expensive Micro SD cards, for 9.99 you can get this 128gb card which works just as well as a known brand of Micro SD card.
I don’t want a phone handset that costs a million pounds, writes blockbuster movies and remotely pilots the space shuttle, so a basic entry level samsung android is ideal – the problem is that they don’t usually have very much internal memory which can fill up very quickly when you add a few apps and take a few pictures.
Installing this card and moving all apps from internal memory to it, changing the settings to save everything to the sd card and regular cloud back ups leaves the internal memory for the pre-installed systems stuff and you’ll never have to worry about running out of phone memory agai
Great value for money.
Cards arrived promptly, storage as advertised and have not had any issued with them after using for several months now in IP cameras as local backup. Would recommend, especially when there is a sale on!
Great SD card for camera
Great quality SD card, fraction of the price of other brands and works just the same! Works quickly in my camera and not come across and slow processing issues. Good levels of storage available. Happy with my purchase
Must have for steamdeck users
Perfect for my steamdeck. No difference while gaming on steamdeck. I have the 512gb version and honestly there is no difference for gaming. In this use case I can recommend this sd card to any deck gamers.
Perhaps slightly longer load times, maybe 5s-10s more for AAA titles. But let’s be honest, steamdeck isn’t built for AAA.
I’m getting up to 100mb/s on this.
Great product and will by another soon.
After seeing some reviews that said it worked and some that said it doesn’t for the Amazon fire kids tablet I thought it’s worth a try for the price. It definitely works, you just have to go into the settings and transfer the data across to the memory card on the adults profile first. Had no issues with storage since!
I bought this for my Kindle Fire Max. Unlike the cheaper 1Tb card I bought from Amazon (not their own brand!) This card went straight in and WORKED – no errors in the formatting. I wish I’d bought this in the first place, it’s a bit more expensive, and a bit less capacity, but I’m much happier with this TF card, and would happily recommend it. It’s worth paying a bit more to get a trustable product!
Works well
I bought one of of these to test it in my action camera. I was curious as it is half the price of my top-branded ones. It works great, so I’ve just bought two more.
My drone SD card had started to fail so I needed a replacement the spec is high for drone use so I was surprised to see this appearing in the search. Having checked and compared the specification it met all my needs and was cheaper than similar cards from well known brands. It also had ya quick delivery time. It arrived as promised and is working well with my drone and has been used extensively with no issues.
Fast delivery and competitive price when compared to similar cards. It works as it should and gets the fifth star when it’s done so for a number of years. What else can you say about a memory card?
