Our Verdict
The Amazon Basics 128GB microSDXC is the budget choice for phone storage expansion, Nintendo Switch libraries, and dashcam use where brand preference doesn't outweigh price. At $33.24, it is the cheapest 128GB microSD in this category, $1.75 less than the SanDisk 128GB Ultra microSD ($34.99). The trade-off is a publicly unpublished read-speed specification; the SanDisk Ultra is rated at 195 MB/s. For loading apps on an Android phone or storing Switch games, the speed difference is imperceptible in daily use. For dashcams or action cameras recording 4K video, a V30-rated card is required, and neither this card nor the SanDisk Ultra meets that bar. For basic phone and tablet storage where lowest price is the deciding factor, the Amazon Basics card is sufficient.
