The microSD card runs in capacities form 16GB to 128GB providing enough space for up to over 40K photos, over 32K songs, or 1,120 minutes of HD video. And with class 10 and V10, the card fully support full HD (1080p) video recording. ![](https://www.storagereview.com/wp-content/uploads/2018/02/StorageReview-ADATA-Premeir-microSD-128GB.jpg) Aside from coming with up to 128GB of capacity, the microSD card also quotes speeds of up to 85MB/s read and 25MB/s write on the sequential side and random numbers of 1,500 IOPS read and 500 IOPS write. Along with that, the microSD card is A1-qaulified, which will help install and run apps faster. For Android devices that support adding a microSD card this will help them simply expand capacity while not losing performance. The ADATA Premier microSD XC/SDHC UHS-I Class 10 comes with a lifetime warranty and the 128GB can be picked up today for $64. **ADATA Premier microSD XC/SDHC UHS-I Class 10 Card specifications:** - Capacity: 16GB, 32GB, 64GB, 128GB - Standard: SD 5.1 - Performance: - Read: 85MB/s - Write: 25MB/s - Speed class - UHS Speed: Class 1 - Speed Class: Class 10 - Video Speed Class: V10 - Operating temperature: -25°C – 85°C - Working voltage: 2.7V-3.6V - Certifications: FCC, CE, VCCI - Dimensions (LxWxH): 15 x 11 x 1mm - Weight 0.25g - Warranty: Lifetime **Design and Build** The microSD card is black with a blue stripe across the top with ADATA branding on the stripe. Beneath the stripe is information such as capacity and class. ![]() The back of the card has the model number and 8 connector pins **Performance** In this review, we will compare the new ADATA Premier microSD XC/SDHC UHS-I Class 10 Card to the following microSD card: [Samsung EVO Plus](https://www.storagereview.com/samsung_evo_plus_microsd_memory_card_review_128gb) Using the [HP Z2 mini Workstation](https://www.storagereview.com/hp_z2_mini_workstation_review) we measured sequential read speeds of 60.6MB/s and sequential writes of 33.41MB/s for the ADATA microSD card. This compared to the Samsung’s 92.15MB/s read and 84.62MB/s write. With random 2MB speeds the ADATA had 50.58MB/s read and 29.81MB/s write compared to the Samsung’s 85.73MB/s read and 1.16MB/s write. For random 4k transfers, the ADATA card hit read 2,971 IOPS read and 1,190 IOPS write compared to the Samsung’s 1,480 IOPS read and 420 IOPS write. **Conclusion** The ADATA Premier microSD XC/SDHC UHS-I Class 10 is the company’s new microSD line that comes with capacity up to 128GB and quoted speeds up to 85MB/s. The card is ideal for expanding capacity in Android devices as it is A1-qualifed ensuring applications install and run at top speed. The card travels well as it is waterproof, shockproof, and x-ray proof as well as antistatic. Looking at performance, the ADATA was able to hit sequential speeds of 60.6MB/s read and 33.41MB/s write, random speeds of 50.58MB/s read and 29.81MB/s write, and random 4k performance of 2,971 IOPS read and 1,190 IOPS write. While it was able to push past the Samsung EVO Plus microSD on some tests (especially the 4k random transfers and random writes) it lagged on others. The ADATA Premier microSD XC/SDHC UHS-I Class 10 card offers a nice performance for a low retail price of $64. While it isn’t as fast as the Samsung EVO in sequential speeds, it more than makes up for it in random performance, not to mention that it is one-third less expensive. For users that need more space in their Android devices or Kindles, it offers more than enough capacity and performance. If performance is what is truly sought, there are better options available for a price. **The Bottom Line** ADATA 128GB Premier microSD XC/SDHC UHS-I Class 10 card offers lots of capacity decent performance, and a good price making it an ideal choice in expanding the capacity of mobile devices.  [ADATA premier microSD on Amazon](http://amzn.to/2BDuwtV) [Discuss This Review](http://forums.storagereview.com/index.php?/topic/40442-adata-premier-microsd-xcsdhc-uhs-i-class-10-card-review-discussion/) [Sign up for the StorageReview newsletter](https://www.storagereview.com/storagereview_newsletter_signup) **Engage with StorageReview** [Newsletter](https://www.storagereview.com/storage_newsletter) |  [YouTube](https://www.youtube.com/user/StorageReview "Opens in a new window") | Podcast  [iTunes](https://podcasts.apple.com/gb/podcast/storagereview-com-storage-reviews/id1060681115 "Opens in a new window")/ [Spotify](https://open.spotify.com/show/1y6VnznABhHeOSMOmbDTz0 "Opens in a new window") |  [Instagram](https://www.instagram.com/storagereview/ "Opens in a new window") |  [Twitter](https://twitter.com/storagereview "Opens in a new window") |  [TikTok](https://www.tiktok.com/@storagereview?
