SanDisk 512GB microSDXC Card Licensed for Nintendo Switch
512GBmicroSDXC UHS-IUp to 100 MB/s readNintendo-licensed-25 to 85 degrees C
The SanDisk 512GB microSDXC (part number SDSQXAO-512G-GNCZN) is a Nintendo-licensed memory card for the Nintendo Switch family, reading at up to 100 MB/s and writing at up to 90 MB/s. SanDisk describes the range as designed, tested and approved for the Nintendo Switch console, and sells it with Nintendo-themed artwork rather than as part of the SanDisk Extreme line.
Important, please read. This part number is from SanDisk's Nintendo-licensed range, not the SanDisk Extreme range. SanDisk publishes only the 100 MB/s read and 90 MB/s write figures for it, and does not publish a U3, Class 10, V30 or A2 rating for this card anywhere in its product page, product features or datasheet. Listings that quote "UHS-I U3, Class 10" are repeating retailer catalogue data, not a SanDisk specification. If you need a card with published video speed and app performance classes, the SanDisk Extreme microSDXC (part number SDSQXAV) is rated at 190 MB/s read and 130 MB/s write with U3, V30 and A2, and includes a full-size SD adapter. No SD adapter is included with this card; SanDisk lists the microSD card alone as the box contents.
Best For
✓ Nintendo Switch storage
Sold under Nintendo licence specifically for the Switch family, which is what it is designed and tested around.
✓ Digital game libraries
512GB holds a large number of downloaded Switch titles, so you stop deleting games to make room.
✓ Straightforward plug-and-play use
The Switch formats and uses the card on insertion with no setup beyond that.
✓ Wide operating temperature
Rated from -25 to 85 degrees Celsius, so it copes with a console carried between cold and hot environments.
Key Features
512GB capacity
A large step up from the 32GB of internal storage a Nintendo Switch ships with.
Up to 100 MB/s read
The read figure SanDisk publishes for this card. Write is up to 90 MB/s. These are identical to the 1TB card in the same range, so capacity does not change the speed.
Nintendo-licensed
Made under licence from Nintendo with themed artwork, rather than being a general-purpose card marketed for the Switch.
microSDXC UHS-I
The standard format and interface the Nintendo Switch family accepts.
Speed and app class ratings not published
SanDisk does not state a UHS speed class, video speed class, Class 10 or A1/A2 rating for this part number. Retailer listings that quote U3 or Class 10 are not sourced from SanDisk.
Wide temperature range
Operating -25 to 85 degrees Celsius, storage -40 to 85 degrees Celsius.

Frequently Asked Questions
Is this the same as a SanDisk Extreme microSD card?
No. This is from the Nintendo-licensed range at up to 100 MB/s read and 90 MB/s write, with no published speed class. The SanDisk Extreme microSDXC is part number SDSQXAV, rated at 190 MB/s read and 130 MB/s write with U3, V30 and A2 ratings and a full-size SD adapter in the box. They are different products at different prices.
Is the 512GB card slower than the 1TB version?
No. SanDisk publishes the same 100 MB/s read and 90 MB/s write figures across every capacity in this range, from 64GB to 1TB. Dimensions, weight, temperature range and warranty are identical too.
Does it come with an SD adapter?
No. SanDisk lists only the microSD card as the box contents for this part number. If you need to read the card in a laptop SD slot, budget for an adapter or a USB card reader separately.
What do I need to know before buying the SDSQXAO-512G-GNCZN?
It is the Nintendo-licensed card rather than the faster SanDisk Extreme, no SD adapter is included, and SanDisk does not publish speed class or app class ratings for it. For a Switch that is fine, since the console is not limited by card read speed in normal play. For a camera or a drone, choose a card with a stated V30 or V60 video speed class.
Singular Expert Insight
The thing to be clear about is which card this actually is. SanDisk sells a Nintendo-licensed range and a much faster Extreme range in the same capacities, and the part number is the only reliable way to tell them apart: SDSQXAO is the licensed one at 100 MB/s, SDSQXAV is the Extreme at 190 MB/s. For a Switch the difference is barely noticeable in normal play, and the licensed card is usually cheaper. Be aware that the U3 and Class 10 markings you will see on many listings for this card are retailer data rather than SanDisk specifications. For a camera or a drone, buy the Extreme instead and check the video speed class. Browse our SD and microSD cards or, if you need to read the card on a computer, our card readers.
Buyer's Guide
Buy this if
You want a large Nintendo-licensed card for a Switch and you are happy with 100 MB/s read for game storage.
Skip if
You need the card for a camera, drone or action cam. Buy a SanDisk Extreme SDSQXAV instead, which publishes V30, U3 and A2 ratings.
Also consider
The 1TB SDSQXAO-1T00-GN6ZN for double the space at the same speed, SanDisk Extreme microSDXC for higher speed and published classes, or a USB card reader.
