This article covers KIOXIA EXCERIA PLUS 256GB microSD.

Overview

KIOXIA (formerly Toshiba Memory) offers the EXCERIA PLUS microSD 256GB, a UHS-I compliant microSDXC memory card that delivers up to 100 MB/s read and 85 MB/s write speeds. This card is optimized for 4K video recording and high-speed data transfers, and it has been verified to work with the Nintendo Switch, making it a safe choice for expanding portable console storage. The NAND flash is manufactured in KIOXIA's own domestic factories, and the card comes with a 5-year manufacturer warranty, underscoring its reliability. The card supports UHS Speed Class 3 and Video Speed Class 30, meeting the minimum write speeds required for continuous 4K recording. It is also validated with GoPro action cameras, making it suitable for outdoor filming. Positioned in the entry-to-mid-range memory card segment, the EXCERIA PLUS offers a strong balance of performance and price.

Compatibility Guide

This microSDXC card works with any device that supports microSDXC: smartphones, tablets, gaming consoles, dash cams, cameras, and PCs via an adapter. It is verified compatible with Nintendo Switch (including OLED model) and Steam Deck. However, it is NOT compatible with Nintendo Switch 2, so next-gen console users should look elsewhere. CPRM (Content Protection for Recordable Media) is not supported, so recorded digital TV broadcasts cannot be played back from this card. For dash cam or surveillance camera use with constant writing, KIOXIA's high-endurance series is recommended instead; the EXCERIA PLUS is not covered under warranty for such continuous recording scenarios.

Product Info

The EXCERIA PLUS 256GB launched in 2025 with a typical street price around ¥7,800 (¥7,800) depending on retailer. The manufacturer provides a 5-year warranty, and the card is sold through major retailers like and electronics stores. Market-wise, this is a mid-range microSD card that balances speed and affordability. While not the fastest UHS-I card available, its stable write performance makes it a reliable choice for 4K capture and game storage. Power consumption is negligible, so it won't impact battery life in portable devices.

Best Use Cases

Nintendo Switch Users: With 256GB, you can store over a dozen large titles like 'The Legend of Zelda: Tears of the Kingdom' without worrying about space. The card's read speeds ensure quick game loading and smooth transitions. 4K Content Creators: Using a GoPro or mirrorless camera? The V30 rating guarantees sustained write speeds for uninterrupted 4K video recording. The fast read speed also speeds up file transfers to a computer for editing. * Smartphone/Tablet Storage Expansion: Many Android devices (and some tablets) support microSDXC for media storage. Moving photos, music, and offline video to the card frees up internal storage, and apps that support adoptable storage can benefit from the card's performance. ## Alternatives
Direct competitors include the SanDisk Extreme microSDXC (UHS-I U3 V30) and Samsung EVO Select microSDXC. SanDisk's Extreme offers higher read speeds (up to 170 MB/s) but may have slightly lower write speeds in sustained benchmarks. The Samsung EVO Select is often more affordable but tops out around 60 MB/s write. The KIOXIA EXCERIA PLUS sits in the middle, offering strong write consistency and a 5-year warranty, making it a good compromise for users who value write performance and reliability over raw read speed.

Things to Consider

The card is not compatible with Nintendo Switch 2, so if you plan to upgrade, look for a card explicitly supporting that system. CPRM incompatibility means it cannot store recorded digital TV broadcasts. Avoid using this card in dash cams or security cameras that constantly overwrite data; the lack of high-endurance design may lead to early failure and voids the warranty. Price-wise, 256GB cards in this class fluctuate often; waiting for a sale can save you a significant amount. For those who need extreme write endurance or higher speeds (170+ MB/s), the SanDisk Extreme or a UHS-II card might be better choices, albeit at a higher cost.
