Good one
on January 2, 2026

[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.
I would recommend this to a friend!

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.
I would recommend this to a friend!

Fast Speeds on my Nintendo Switch 2
on January 6, 2026

[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.
