Our Take

Best for: Android phone or tablet users needing more storage for apps and media.

The ADATA Premier 128GB microSDXC card is a straightforward storage upgrade. You would pick this to add space to a smartphone, tablet, or action camera without spending a lot. It handles photos, videos, and music just fine. What stands out is the A1 application performance rating, which means it can run apps from the card on Android devices better than a basic storage card. The 100MB/s read speed is good for pulling files off the card quickly. A notable limitation is the 25MB/s write speed. It's sufficient for general use like saving photos, but it's not the fastest for recording very high-bitrate 4K video. At this sale price, it's a worthwhile buy for most people who just need reliable, extra storage. It's a known brand offering good value for the capacity and speed tier.

Price Analysis

At $15.32, this card is 35% off its listed original price of $23.52. The 90-day average price was around $20.66, so the current sale is a significant drop from recent prices. This is a very good time to buy for this model.
