This article covers TRIDENITE 185MB.

Overview

The TRIDENITE TCRS-M32C128 is a compact USB-C microSD card reader bundled with a 128GB SPEEDY microSD card. It supports UHS-I DDR200 and USB 3.2, delivering read speeds up to 185MB/s and write speeds up to 135MB/s. The reader itself weighs just 2.3g and measures 30.25 x 15 x 8.25mm, making it one of the most portable OTG adapters on the market. This bundle is designed for users who need a ready-to-go solution for transferring photos, 4K videos, and game data between smartphones, tablets, and computers. It works with iPhone 17/16/15 series, Android devices, Windows PCs, and Macs. The included 128GB card is pre-formatted and ready for immediate use.

Connectivity & Compatibility

The reader accepts microSD, microSDHC, and microSDXC cards, including Application Performance Class A1 and A2. It connects via USB Type-C (USB 3.2 Gen 1) and supports OTG for direct connection to Android smartphones and tablets. Compatible operating systems include Windows Vista through 11, macOS 10.X and later, iOS (iPhone 17/16/15), and Android. Note that devices with a USB-A port will require a separate adapter, and older iPhones with Lightning connectors are not directly compatible. The reader is also suitable for use with cameras, drones, and game consoles that use microSD cards.

Product Info

The TRIDENITE TCRS-M32C128 was released around 2024 and is available exclusively through at approximately ¥3,999. The package includes the card reader and a 128GB SPEEDY microSD card. No additional cables or adapters are needed for Type-C devices. The product comes with a 2-year warranty covering initial defects. Positioned as an entry-to-mid-range bundle, it offers excellent value by combining a high-speed reader with a decent-capacity card. For users who don't already own a fast microSD card, this all-in-one package saves both time and money compared to buying components separately.

Best Use Cases

iPhone 17/16/15 users: Quickly back up photos and videos from your iPhone to the microSD card or transfer files to a PC. The reader is plug-and-play with the iPhone's native Files app. Smartphone storage expanders: If your Android phone has a microSD slot, you can use the included 128GB card to store apps, photos, and media. For phones without a slot, use the reader to offload files to a computer. Content creators with drones or action cams: Transfer 4K footage from a microSD card to a laptop or tablet at high speed. The 185MB/s read rate significantly reduces wait times for large video files. Not ideal for: Users who already own a fast microSD card and only need a reader, or those who require full-size SD card support. Also, if your primary computer lacks a USB-C port, you'll need an adapter.
