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.

[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.

[This review was collected as part of a promotion.] The Samsung P9 Express microSD Express Card, is a nice attractive product that appears to be well constructed. It arrived in good condition.
The Samsung P9 Express microSD Express Card was used to transfer data and used in my camera, with read speeds up to 800 MB/s the speeds are comparable to USB 1 speeds. Data transfer was fairly constant during downloads/uploads. The quality of photos was very nice as opposed to other microSD cards used in the past. The microSD card worked well with my micro to macro adapters for testing. Not being a gamer, I was not able to test this in that manner.
After testing I will purchase The Samsung P9 Express microSD Express Card in the future.

Great card for the switch 2

[This review was collected as part of a promotion.] I picked up the Samsung P9 Express microSD Express Card to use with my Switch 2, and it’s been solid so far. Setup was easy. Just popped it into my switch 2 and it worked great. The switched formatted it with no issues.
Performance has been fantastic. Games install quickly, load times are just as fast as the onboard storage. I haven’t seen any stuttering or slowdowns when launching or switching between titles. If I didn’t know there was a microSD card inserted I would have thought the games were installed on the internal memory.
Overall it has been easy to use, and fast enough that I don’t even think about it . If you’re looking to expand storage without sacrificing performance this card is it!

[This review was collected as part of a promotion.] Holy smokes
I never knew memory cards could
Go any faster I thought that they all had the same speed, boy was I wrong. Pictures load up faster than I ever imagined. Transferring files., well that is a breeze. Unbelievable Samsung. I will not only sing the praises of this great card, but I will also sing the praises of Samsung in general. These folks know what they are doing. It’s going to be amazing to see what it is that they will put out next. When the time comes, I will be right there ready to try it out and provide my thoughts. Astounding, Amazing, Unbelievable, and unreal. These are just a few words that even BEGIN to start to describe this product. Don’t delay. Go buy it today.

Great MicroSD Express card for Switch2
on December 29, 2025

[This review was collected as part of a promotion.] Off the bat, I have been impressed by the speed of this P9 microsd express card. I have transferred a few games from my switch2's internal memory to the card and for 60gb of data, it took about 15 minutes. Booting times for games off the P9 microsd card has been near indistinguishable from my systems internal memory. What helps with keeping those boot up times fast is the thermal guard which keeps the card from overheating. On top of that, I love having the peace of mind that this card will take on everything I throw at it with the 3 year warranty Samsung includes with the card. Would recommend for anyone that wants to increase their gaming experience seamlessly.
