[This review was collected as part of a promotion.] As a dedicated Nintendo Switch gamer, I’ve been looking for a microSD card that can handle my growing game library, and I’m thrilled to say that the Samsung P9 MicroSD card has exceeded my expectations. Using this card to migrate the games from my system to the external storage it fast at up to 800MB/s, and the microSD card is super reliable. This microSD card being waterproof, and shock proof is amazing for a portable console.
I would recommend this to a friend!

[This review was collected as part of a promotion.] If you are buying this, it is probably for your Switch 2. It works perfectly and has no issues. I love that it is insanely fast compared to traditional micro SD cards. You are getting over 60,000 IOPS here, whereas standard ones usually struggle to hit 3,000. It’s a no brainer if your device supports it even if it was not for the Switch. Since the Samsung P9 Express micro sd card is a new product, I cannot say much about its longevity yet. However, Samsung is a very reputable brand when it comes to memory cards. I am happy with the performance and the sense of security that my card will last for a long time.

Great Storage Upgrade for My Device

[This review was collected as part of a promotion.] I’ve been testing the Samsung P9 Express microSD Express card for a few days and my experience so far has been very positive. Installation was simple and the micro SD card was recognized instantly by my device. What stood out immediately was the speed. Game load times felt noticeably quicker, and transferring large files was faster and smoother than what I’m used to. Even switching between games feels more seamless now.
The micro SD card itself feels sturdy and well made, and I like that it works with devices that support newer speeds as well as older ones. I haven’t had any errors, lag, or corrupted files during testing. Overall, the performance has been reliable and consistent.

Fast, reliable microSD card!

[This review was collected as part of a promotion.] I used this on Nintendo Switch 2 and the only game I have is Mario Kart and had zero issues with read/write speed. I realize Mario Kart isn't the fastest and/or most memory hungry game to run so I decided to test with some 4K drone footage with my DJI Mavic. I flew and recorded for 18+ minutes (max on that specific battery at highest resolution) and this was my litmus test. It's high-speed writing test and it passed with flying colors. No lag, no issues, not a blip!
One thing I would have appreciated is a dongle or USB plug in for the microSD card. This is just a standalone microSD card but this is also meant for just game consoles so I get why they didn't include it. After shooting the video footage, I was scrambling to find a dongle of sort to plug into my TV to see how the recording turned out. Had to settle for computer since no dongle/card reader was provided.
But overall, solid microSD card - ample fast for gaming and even high resolution 4K video recording. I'd definitely recommend this!

A Must Have for Your Switch

[This review was collected as part of a promotion.] THIS is what you need for your Switch 2! It's much faster than a standard microSD card and loading times aren't much slower than having games installed on internal storage. Even when my switch was running a little warm, my game loading times were still consistent. I wish there was something more discernable on the packaging to let you know it's a special microSD Express card but if you're someone specifically looking for this card then you know what you're looking at. Overall, this microSD Express card is still a big performance jump when compared to a top performing microSD card.

Get it!

[This review was collected as part of a promotion.] You'll be needing the extra storage on your Nintendo Switch 2. Especially with the size of the new games that are coming out for this system. This is a definite buy for me. It's fast and reliable, Samsung has been tried and true in this space. I use their cards for my photography and haven't had any issues. I really apreciate how much faster the Express cards are to normal microSD cards. Having this much storage makes it easy to store my digital game cartridges and not have to worry about not having the games I want when travelling. The install was instant. Also, yes it can work for other applications but the Switch 2 is the one requiring a microSD Express at the moment.

[This review was collected as part of a promotion.] The Samsung microSD card is everything you’d expect in a memory card. It works perfect in the Nintendo Switch 2. It fast when transferring files to and from it. The microSD card helped to move some downloaded games to my new console. Everything downloaded quickly, then was easy and quick to start up on the switch 2. It has made my life easier as a gamer as well as a parent. Fast and efficient product. Highly recommend.
