Handheld gaming community members asked me about pad thermique steam deck replacement maintenance 40+ times in the last month. Here's the consolidated answer.

TL;DR: the WD Black SN770M 1 TB NVMe 2230 is our top pick ($95-130). Why: m.2 2230 form factor — steam deck / rog ally x compatible. Budget alternative: SanDisk Extreme microSDXC 1 TB.

Buying mistakes specific to handhelds

  • Forgetting form factor (M.2 2230 vs 2242 vs 2280 — not interchangeable)
  • Confusing UHS-I and UHS-II microSD (Steam Deck only reads UHS-I)
  • Overlooking power delivery spec on USB-C cables (cheap ones cap at 20W instead of 65W)
