MicroSD Card - Samsung

[This review was collected as part of a promotion.] This card is crazy fast. The Samsung P9 Express is noticeably quicker than any regular microSD card I’ve used before. File transfers are almost instant, apps load faster, and it handles 4K video and gaming without breaking a sweat. Setup was simple—just plug it in and go. I am currently using mine in my digital picture frame, as I might have ALOT of images transferred over.
If your device supports microSD Express, the speed boost is absolutely worth it. OF NOTE: You may need an adapter if your item does not take the micro.
Fast, reliable, and future-ready. Highly recommend.
I would recommend this to a friend!

Speed + Simplicity. Samsung’s P9 rocks!

[This review was collected as part of a promotion.] As the owner of a new Switch 2, I quickly discovered that a memory card is probably the most essential accessory to own. Not only will it give your system some much-needed capacity for games and other system settings, it will also free up some system resources and ensure that the system runs efficiently.
Samsung’s P9 microSD Express Card might be tiny but it packs a punch - it’s speedy, it offers wear out-proof performance with water, temperature, x-ray, magnet and drop resistance, and it’s useful with a variety of devices. With the card installed in my Switch 2, gameplay was fast and fearless. I also tried this card in an Osmo camera, and it captured my shots smoothly.
Installing the card is as easy as putting it into the device’s card slot. It requires no additional setup and in the Switch 2, it shows the advertised capacity right away. Don’t bother shopping around; if you’ve got a Switch 2, this is the only memory card you need.

[This review was collected as part of a promotion.] The Samsung MicroSD Express Card P9 is the best card money can buy on the market. If you need an upgrade for your Nintendo switch 2 this is the one for you. Compared to others the Samsung MicroSD Express Card P9 this is clearly better in all ways from storage size, speed, and definitely cost. The Samsung MicroSD Express Card P9 in my opinion has bridged the gap to internal SSDs. No need to carry an SSD drive with this powerful microSD Express card on hand. It’s been super-fast while using it with my Nintendo Switch 2 and other devices when using the proper hardware. In my opinion 800 MB/s is unheard of and somewhat unreal and it doesn’t miss a beat with no lag time. That is about four times faster than anything else I have heard of or used. Installation and Updates along with downloading small to large files are simple and much quicker with this powerful card. This will help with eliminating downtime and give you max playtime, which is very important to everyone. Samsung has changed the game by including high-end features like Dynamic Thermal Guard (DTG), and Backward Compatibility just to name a few that’s normally only included and reserved for internal SSDs, into this microSD card. Keep in mind this MicroSD card also works great with a wide range of today handhelds, cameras, tablets, and microSD Express–ready devices. This MicroSD Express Card fully supports microSD Express, the card unlocks its maximum speed potential of 800 MB/s, delivering a noticeable performance improvement right out of the box. If you are on the fence about buying a new MicroSD card, I highly recommend the Samsung MicroSD Express Card P9. If you need an upgrade for your Nintendo switch 2 or any other device, this is the one for you.

Fast and Reliable

[This review was collected as part of a promotion.] I just bought a Switch 2 for the holidays, and was looking for a new micro SD card that works with it - this one was perfect! It's super fast and reliable, and the download and file transfer speeds seem better than other micro SD cards I've used in the past.
I redownloaded my whole digital collection onto my Switch 2, and everything plays great and loads very quickly even though the games are saved to the card instead of the console. I picked up the 256gb card and maxed it out with my whole digital library, and still have most of my console storage left, so it's a good size for what I need for now. I'll probably upgrade to a 512gb eventually, but loving it so far.

My Camera AND my Laptop THANK YOU

[This review was collected as part of a promotion.] I use this card in my camera for the extra storage and super fast write speeds. I have literally been though 100's of cards. Some photograph well, but when I transfer to the computer, I am sooooo frustrated by how long it takes. I was extremely happy when I tried this card. The speeds were great and it didn't take me 20 minutes to transfer a full card. Time is money and the less time I spend watching a green bar creep across a screen, the better it is for me. My digital camera is prone to overheat on warm days when I am shooting a lot, so I'm looking forward to see if the "Thermal Protection" can help with that.

[This review was collected as part of a promotion.] When I saw the option to test this card I was excited. I recently purchased a Switch 2 and this type of card was the only type that works with it. I was able to pop in it int Switch and it was recognized with no issues. Games loaded quickly and I didn't see any difference between the local storage. Works great! I also really appreciate that I can feel safe using it with all the protection this card comes with. 6 types of protection- water, temperature, X-ray, magnet, drop and wearout-proof.

Speeds the games up!

[This review was collected as part of a promotion.] I was so excited to try out the Samsung P9 Express microSD Express card. It was perfect timing because we just got a steam deck and I’ve heard how using P9 Express microSD Express card was perfect to really maximize the efficiency of the steam deck. Plus the microSD card has so many protection! It’s water proof, temperature proof, magnet proof, drop proof, and so on. It’s an incredible variety of protections. I am very clumsy and am glad to know if I drop it when switching devices or water gets on it, etc that there is a great level of protection on it.
Once we received the Samsung P9 Express microSD Express Card, I immediately installed it in the steam deck. It was great to have the options to load games on the sd card instead of the internal memory. Using the P9 Express microSD gave a difference in the playability since I can load games from the sd card instead of internal memory. I can never game without the P9 Express microSD Express card again. I will purchase this to try in other devices with next generation hardware with speed microSD capabilities like digital camera, laptop, and Nintendo switch 2. Samsung is a trusted brand we will always use. Also, the three year warranty is amazing and makes being a loyal customer a no brainer.

[This review was collected as part of a promotion.] We recently received the Samsung P9 Express microSD Card for the use in our family Nintendo Switch 2 console. It has been an impressive micro SD card that has left a lasting impression in this gaming household so far. With its fast loading speeds for all of our digital gaming has improved significantly especially for older games. Install and transfer of data is a breeze. We don’t feel our console is lagging after we transferred all the data over too. Simply put it, it’s an item we should have invested in from the get go with Samsung.
