Transcend 128GB UHS-I microSDXC Overview

Upgrade the storage and performance of your mobile device using the 128GB 300S UHS-I microSDXC Memory Card from Transcend. Designed to retrieve small pieces of data from random locations and improving app launch times, the 300S has a capacity of 128GB, supports the UHS-I bus, and features a speed class rating of V30, which guarantees minimum write speeds of 30 MB/s. If your device does not support the V30 standard, this card also supports the U3 standard, which likewise guarantees minimum write speeds of 30 MB/s. Read speeds are supported up to 95 MB/s and write speeds max out at 40 MB/s, also making this card suitable for Full HD, 3D, and 4K Video, plus raw and JPEG still photos and bursts.

While this card has been designed for cameras that are UHS-I / V30 / U3 compatible, it may be used in devices that do not support UHS-I / V30 / U3. However, bear in mind that this card will then default to your device's speed class and bus rating, such as UHS-I and U1, which support minimum write speeds of 10 MB/s, or Class 10, which also supports minimum write speeds of 10 MB/s.

Aside from support for UHS-I, V30, and U3, Transcend also built this card with support for the Application Performance Class 1 (A1) spec, which includes optimizations to give Android users an improved mobile experience, delivering faster mobile app performance. The A1 spec allows the card to manage random read input-output access per second (IOPS) operations so it can quickly open apps and process accompanying tasks, such as audio, graphics, saved profiles, and in-app permissions.

As with most Transcend cards, this memory card is shockproof, X-ray proof, and waterproof, while also being able to withstand static, plus temperatures from -13 to 185°F, allowing you to take this card with you into extreme environments. Should the card's data become compromised, you also benefit from Transcend's free RecoveRx software for to help recover deleted content, including photos, documents, music, and videos. So that this card may be used in SD-compatible devices, a microSD to SD adapter is included.

Will this work with the Sony a6300 on 4K 100 Mbps?
Asked by: Elliot
While this card has the proper V30 rating for 4K 100 Mb/s recording on the A6300, we do not recommend using Micro SD Cards with an adapter on a card that has a full size SD Card port. It is best practice to use the full size SD cards in a camera like the A6300. The SanDisk 128GB Extreme UHS-I SDXC Memory Card, B&H # SAESD128GBA, has the proper V30 rating as well and is a much better choice. https://bhpho.to/2NsxiKl

Zoom recommends this card for their Zoom F3 , however, their model number DOES NOT end with an "-a" like this one. For example, TS512GUSD300S, not TS512GUSD300S-a. My question is, can I this one?
