Frequently Asked Questions

What SD Card Do I Need for MacBook Air?
The MacBook Air takes a External via USB-C Reader card rated UHS-I recommended or faster. 128GB or 256GB covers most owners, and the maximum is undefined. Buy SanDisk, Lexar, Samsung or Kingston from a reputable seller: counterfeit cards are the most common cause of lost files.
Is UHS-I recommended required for MacBook Air?
Yes. UHS-I recommended is the minimum that keeps the MacBook Air free of slow loads, stutter, or write errors. Faster cards work too.
What size SD card should I get for MacBook Air?
128GB covers light use; 256GB suits heavy use.
Can I use older or slower cards with MacBook Air?
Not below UHS-I recommended. Slower cards cause slow loads, stutter, or write errors. Check the card label for the UHS-I recommended mark.
Should I use more than one card with MacBook Air?
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.

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.

A card slower than UHS-I recommended 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 MacBook Air?
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.
