Frequently Asked Questions
Can I use the SanDisk 128GB Ultra microSDXC card in my Nintendo Switch?expand_more
While many users successfully use SanDisk Ultra cards in their Nintendo Switch, there are reports of cards failing or causing issues. We recommend checking Nintendo's official compatibility list and purchasing from authorised retailers to minimise risk.
How do I know if my SanDisk 128GB Ultra microSDXC card is a fake?expand_more
Common signs of a fake card include incorrect capacity readings (e.g., showing 31.6MB), extremely slow transfer speeds, failure to be recognised by devices, and non-functional adapters. Performing a card testing utility can help verify its true capacity and speed.
What is A1 performance rating on a microSD card?expand_more
The A1 rating signifies that the SanDisk Ultra microSD card is optimised for application performance. It guarantees a minimum of 1500 input/output operations per second (IOPS) for random reads and 500 IOPS for random writes, leading to faster app launches and smoother operation on Android smartphones and tablets.
Are the advertised speeds of 140 MB/s achievable for the SanDisk 128GB Ultra?expand_more
The 140 MB/s is the maximum advertised read speed, and achieving this often requires specific host devices and conditions. Real-world write speeds are typically lower and can vary significantly depending on the device and usage, with many users reporting speeds well below the advertised maximum.
Can I use this 128GB microSD card to store 4K video?expand_more
While the card has ample capacity for 4K video storage, its U1 and A1 ratings, along with often lower write speeds, make it less ideal for recording 4K video continuously. For reliable 4K recording, a card with a U3 or V30 rating is generally recommended.
What is the difference between SanDisk Ultra and SanDisk Extreme cards?expand_more
The SanDisk Ultra is positioned as a mid-range card for everyday users, offering good value and A1 app performance. The SanDisk Extreme and Extreme Pro lines are higher-end, offering significantly faster read and write speeds, making them more suitable for professionals, 4K/8K video recording, and intensive applications.
Is it safe to buy SanDisk cards from third-party sellers on Amazon or eBay?expand_more
We advise extreme caution. While legitimate sellers exist, many reports of counterfeit SanDisk cards originate from third-party marketplaces, especially during sales. Purchasing directly from SanDisk or a well-known, authorised retailer is the safest approach.
