Patriot V30 A1 microSD Card 64GB

Overview

A 64GB microSD with genuine app-class and 4K video speed ratings, priced as a workaday card rather than a specialty one.

A1 and V30 are the two ratings that matter for this card's real use: A1 covers app read and write performance for Android devices that support app storage on microSD, while V30 guarantees a sustained 30MB/s write floor for video capture. Patriot lists up to 100MB/s read and 80MB/s write, both above the V30 minimum.

• A1 application performance class
• V30 video speed class for 4K
• Rated up to 100MB/s read, 80MB/s write
• 64GB capacity

Who it's for

Works for Android phone owners who want to move apps or media to the card, and for anyone recording 4K on a device with a microSD slot, such as an action camera or drone. Not a fit for a device that only supports older, slower card classes, since A1 and V30 speeds go unused there.

Pros and cons

Performance notes

The A1 rating means the card meets minimum random read and write IOPS for running apps rather than just storing files, so app load times on a card-expanded Android phone stay closer to internal storage. The V30 rating guarantees a 30MB/s minimum sustained write speed, which is what keeps 4K footage from dropping frames mid-recording; Patriot's rated ceiling of 80MB/s write and 100MB/s read gives headroom above that floor.
