This is a 512GB microSD Express card for Switch 2, and the main draw is that it meets the console's required Express standard rather than regular microSD. The Costco price lands below Walmart and far under other major retailers, with historical pricing for 512GB Express cards making $89.99 look solid. It also appears in the Costco app at some locations, sometimes at $79.99, and can be found in store even when it is not on the floor. The main caution is that shipping has had a known website error, and the card is only worth comparing against other Express models because standard microSD cards will not work.

Common Questions (5)

  • Yes. It is a microSD Express card, which Switch 2 requires, and standard microSD cards will not work. Express cards are also much faster than regular SD cards, which is why compatible models cost more.

  • Costco's price is $89.99, which is below Walmart's $98 listed price and far under Amazon, B&H, Micro Center, SanDisk, and Best Buy in the comments. One app listing also showed $79.99 at some warehouses.

  • For Switch 2-compatible storage, 512GB microSD Express cards were reported as only dropping to about $65-$70 in 2025, with typical pricing around $80, so $89.99 is still considered a solid buy. Regular 512GB microSD cards can be much cheaper, but they are not the same product.

  • Yes. The item can be found through the Costco app by item number, and some warehouses have stock in the back even when it is not displayed on the floor. The app listing also showed multiple nearby stores with inventory.

  • It can be worth testing before relying on it. One reported h2testw run failed at first, then passed after switching computers and using a different card reader, suggesting the issue may be the reader, USB port, or the card itself.

You're good Smilie didn't want my thread/comments to come off as misleading in any way.

This is actually a good deal.
I bought the same exact card from Walmart in July 2025 for $78. Right before RAM prices soared.
So compared to RAM and SSDs, a price jump of $11 is not that bad for SD Express.

I really hope the golden days to come back : $22 for 512GB on Apr 7, 2025 -- https://slickdeals.net/f/18234763-sandisk-512gb-imagemate-pro-microsdxc-uhs-1-memory-card-with-adapter-up-to-200mb-s-sdsqxbd-512g-aw6ka-21-53

Edit : Damn people! understand the intention, I am not saying the same card was sold for $22. I just want the low price memory days to come back!

Finally getting around to test mine.

Failed the first h2testw. Switched computers and trying a different SD card reader.

For the first run, it could be anything from the USB port, to the card reader, to the SD card. It took nearly four hours to write everything. Total read time is almost 2 hours. I think the errors happened around the hour mark but I wasn't paying attention.

edit: tested on other SD Card reader and computer. no errors.

Out of stock all over the bay area per usual
Use the costco app search item #1977671 in wearhouse

I found it in San Leandro, CA, it wasn't on the floor, but I bought at checkout by giving the item # and they had it available in the back.

I can see in the app, Foster City, Danville, San Francisco, S San Francisco, Newark, Pleasanton, San Leandro have it in stock

price was $79.99
