SpecPicks Verdict
SpecPicks scored Lexar E-Series 128GB 2 PK Micro SD Card microSDXC UHS-I Flash Memory… using a rating × review-volume × price-fit model applied to published specs and reviews across the storage adapters category. Lexar's storage adapters lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.
Common buyer scenarios for storage adapters of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase. Prices and stock are set by the retailer and may have moved since this page was last updated.
Key Features
- Wide Compatibility: Ideal for your smartphones, tablets, Drones, action cameras and Gopro. Premium memory solution for smartphones, tablets, or action cameras
- 4K Ultra UHD: Quickly captures, plays back, and transfers media files, including 1080p Full-HD, 3D, and 4K UHD video
- High Speed Memory Card: Leverages UHS-I technology for a transfer speed up to 100MB/s. Loads apps faster with A1-rated performance. (Based on internal test environment of Lexar, so the actual speed may vary with different host devices and environments. For devices that don't support UHS-I, the transmission speed will be different due to interface limitations.)

(Due to different capacity algorithms and partial capacity are used for system files, management and performance optimization, so the actual available capacity may be less than the identifying capacity.)
