This onn 128 GB microSDXC card stands out as a budget 128 GB option for Nintendo Switch and camera storage, with read speeds up to 100 MB per second and write speeds up to 90 MB per second. It has been used successfully in eufy and Tapo cameras, and the Taiwan manufacturing and relabeling speculation points to a lower tier but workable card. The main cautions are compatibility and durability, since Switch 2 needs MicroSD Express, some modded Switch setups hit errors, and long term reliability is questioned. The price is still viewed as strong versus current 128 GB alternatives.

Common Questions (5)

  • Yes, it is considered a good price given recent microSD price increases and is far below the $30-$40 range seen for many other 128 GB cards. In-store pricing may be even lower in some locations, with one card marked $9.67 reduced.

  • No. Nintendo Switch 2 requires MicroSD Express, so this standard microSDXC card is not the right format for that console.

  • It has been used successfully in eufy and Tapo cameras, with multiple cards bought for those setups and reported working well. It is not a high-endurance card, so it is better for budget camera storage than for critical data.

  • Yes, it is intended for the Nintendo Switch family that uses standard microSD cards, and the Switch uses a slower speed format. One buyer had errors when trying it on a Switch Lite and Switch v2, so it should be checked against your specific setup before relying on it.

  • It is rated for read speeds up to 100 MB/s and write speeds up to 90 MB/s. That makes it suitable for general storage and camera use, but not a substitute for faster formats like MicroSD Express.

Can you explain why?
Use a memory card that is compatible with your device.

Not all memory cards are built the same. Some have more pins on the back of the card to support faster speeds. If you're GoPro/dashcam needs faster speeds, it's not going to work with a card that's built for slower speeds. The Nintendo Switch uses a slower speed format.

Lexar is owned by Longsys, the cards are made in Shenzhen, China
Correct. Onn microSD Express cards are made in China by Longsys, but Onn's standard microSD cards are made in Taiwan, so I'm curious who the OEM is.

Got these a few weeks back for my eufy cameras. I know I know they aren't high endurance but took my risk. Made in Taiwan. I suspect based on the price and location of manufacturing they are made by Silicon Power and relabeled. More of a budget drive but hopefully a little more endurance given they are switch branded. They have been working good
I am thinking of exactly the same thing for my eufy cameras. Ever other 128gb are like $30-$40+, wished I had bought more Samsung ones when it was under $20 a few years ago...

For those who are willing to go in store - the one I got was marked $9.67 reduced on 5/15/26. YMMV

128gb standard microsd cards should be "free" by now.
