Frequently Asked Questions
What SD Card Do I Need for GPD Win Mini?
The GPD Win Mini takes a microSD UHS-II (Supported) card rated U3 / V60 / V90 or faster. 512GB or 1TB or 2TB covers most owners, and the maximum is 2TB. Buy SanDisk, Lexar, Samsung or Kingston from a reputable seller: counterfeit cards are the most common cause of lost files.
Is a UHS-II card worth it for the GPD Win Mini?
Only if your model's reader supports UHS-II. In a UHS-I slot the card runs at UHS-I speed.
Is V60 required for GPD Win Mini?
Yes. V60 guarantees 60 MB/s of sustained write, which keeps the GPD Win Mini free of slow loads, stutter, or write errors. Faster cards work too.
What size SD card should I get for GPD Win Mini?
512GB covers light use; 2TB suits heavy use. The maximum is 2TB.
Can I use older or slower cards with GPD Win Mini?
Not below U3 / V60 / V90. Slower cards cause slow loads, stutter, or write errors. Check the card label for the U3 / V60 / V90 mark.
Do I need a UHS-II card for GPD Win Mini?
No, but it helps. The GPD Win Mini has a UHS-II slot, so UHS-II cards write and offload faster. UHS-I cards work at UHS-I speed.
Should I use more than one card with GPD Win Mini?
For long shoots, yes. Two mid-size cards cost about the same as one large card, and a failure then loses half your files instead of all of them.
Does the brand matter for GPD Win Mini?
Yes. SanDisk, Lexar, Samsung and Kingston cards meet their rated speeds. Buy from the brand's store or a major retailer: counterfeit cards sold under those names are common on marketplaces.
What happens if I use the wrong card with GPD Win Mini?
A card slower than U3 / V60 / V90 causes slow loads, stutter, or write errors. A card over the maximum capacity or in the wrong format may not be recognized.
How long will an SD card last in GPD Win Mini?
Several years in normal use. Cards usually fail from wear or counterfeit flash, not age. Replace yours at the first write error, corrupted file or "card not recognized" message.
