Users are overwhelmingly positive about this Samsung PM991a SSD, especially as a Steam Deck upgrade from the 64GB eMMC. They praise its ease of installation, performance improvements, and value for money. Some noted minor issues with SteamOS reinstallation and the drive's slightly taller profile, but these were not deal-breakers.
