Our Take

Best for: Gamers upgrading Steam Deck or ROG Ally storage.

2 2230 form factor, making it perfect for handheld gaming PCs like the Steam Deck and ROG Ally.

It also supports Microsoft DirectStorage for improved game performance. The TLC 3D NAND ensures longevity, and the 1TB capacity provides ample space for a large game library. 2 2280 slots without an adapter, that's by design for compact devices. 99 (20% off), this is a solid upgrade for handheld gamers who need more storage without sacrificing speed. The included 5-year warranty adds peace of mind.
