[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.
I would recommend this to a friend!

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!
I would recommend this to a friend!

[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.

Good one

[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.

Fast, Reliable Storage for Switch
on January 2, 2026

[This review was collected as part of a promotion.] I’ve been using the Samsung P9 Express microSD Express Card with my Nintendo Switch, and it’s been a true plug-and-play upgrade. The card snapped right into the slot, the system formatted it instantly, and I was downloading games within minutes. The extra storage is exactly what I needed since my digital library keeps growing faster than I’d like to admit.
Performance-wise, it’s been every bit as fast as the Switch’s built-in storage. Games install quickly, load times feel snappy, and switching between titles is seamless. If I didn’t already know the games were running off a memory card, I honestly wouldn’t have noticed a difference. It’s one of those upgrades you stop thinking about because it just works.
As a nice bonus, the card is built to handle real-life mishaps. It’s waterproof and clearly made with durability in mind. For something that holds all my saves and downloaded titles, that peace of mind matters. Overall, this has been a simple way to expand storage without sacrificing performance, and I’d absolutely recommend it to any Switch owner running out of space.

Fast Speeds on my Nintendo Switch 2

[This review was collected as part of a promotion.] This is an excellent product. Bought this to add storage capacity to my Nintendo Switch 2 and it delivers as promised. Very fast speeds highly recommended for anyone looking to add capacity to any of their devices at an extremely fast read/write speeds. I put into my console and as soon as I did it detected and formatted it properly. Games load extremely quickly and load as quickly as they do when save onto the internal storage. I knew with a trusted brand name such as Samsung that this would be an excellent product and as expected it delivers.
Way to go Samsung, another home run with a great high quality product. I'd recommend to anyone looking for a memory card to upgrade their Switch 2 or other devices.

FAST

[This review was collected as part of a promotion.] Yet another option out there for the new microSD standar. The Express card from Samsung is a nice option to have. Of course you'll need one for the new Switch 2 you just bought since all of the new Switch 2 games are massive compared to the previous generation's games. Most microSD cards (that aren't overly priced anyways) don't really go past 200 mb/s while this one hits 800. If you have someone who owns a Switch 2 it would make a great gift.
