Comprehensive Guide to the Best SSDs for Steam Deck in 2023

The Steam Deck's Storage Dilemma

Originally, the Steam Deck's storage capacity was a modest 64GB. Gamers quickly sought ways to expand this, including external storage or microSD cards. However, upgrading the internal SSD emerged as the most reliable and fastest solution. The unique requirement for the Steam Deck is an M.2 2230 single-sided SSD, crucial for maintaining WiFi functionality and cooling efficiency.

Selection Criteria for Steam Deck SSDs

When choosing an SSD for the Steam Deck, several factors come into play:

  1. Form Factor and Compatibility: The SSD must be in the M.2 2230 form factor and single-sided for compatibility with the Steam Deck’s design.

  2. Performance Efficiency: PCIe 4.0 drives are compatible and more efficient at lower speeds, crucial for portable devices like the Steam Deck where heat production and battery life are key concerns.

  3. Capacity and Power Consumption: Larger-capacity drives may draw more power and generate more heat. It's essential to balance capacity with the device's thermal and power capabilities.

  4. Consistent Performance: Given the gaming nature of the Steam Deck, SSDs should provide quick game loading times and maintain consistent performance even when the drive is near full capacity.

  5. Real-World Testing: We evaluated the SSDs through both standard and specialized tests, including PCIe 3.0 and 4.0 modes, to assess their compatibility with the Steam Deck and other gaming handhelds.
