Leaked GameStop SKUs Suggest Nintendo Switch 2 Will Support microSD Express Cards

Recent leaks point to a significant upgrade in the Nintendo Switch 2's storage capabilities. Several GameStop stock keeping units (SKUs) seemingly referencing unannounced Switch 2 accessories have surfaced, hinting at support for microSD Express cards. This suggests substantial improvements over the original Switch's UHS-I microSD card support.

The leaked SKUs, initially shared on Reddit, list "Switch 2 Exp Micro SD Card" products in 256GB and 512GB capacities. This strongly indicates compatibility with the microSD Express standard, a technology offering dramatically faster transfer speeds and larger storage capacities than UHS-I.

A Massive Speed and Capacity Boost

The current Nintendo Switch utilizes UHS-I microSD cards, achieving practical transfer speeds around 95 MB/s. In contrast, microSD Express cards boast speeds approaching 985 MB/s – a nearly 900% increase. This dramatic improvement is attributed to the microSD Express standard's use of the NVMe protocol, similar to that found in high-performance SSDs.

Furthermore, while UHS-I cards are limited to 2TB, microSD Express cards can reach capacities of up to 128TB – a staggering 6,300% increase.

Pricing and Other Leaks

According to the leaked GameStop inventory, the 256GB Switch 2 microSD Express card will retail for $49.99, while the 512GB version is listed at $84.99. Additional SKUs were also discovered for a standard Switch 2 carrying case ($19.99) and two "deluxe" cases ($29.99).

These leaks follow a pattern of unofficial Switch 2 accessory information circulating online for months. Nintendo has previously stated its intention to officially unveil the Switch 2 before the end of its fiscal year (March 31, 2025), leaving a limited window for an official announcement.

The consistent flow of leaks, including these GameStop SKUs, strongly suggests an imminent official reveal of the Nintendo Switch 2 and its enhanced storage capabilities.
