128GB – £19.00 · 256GB – £29.00 · 512GB – £49.00

(Genuine SanDisk Ultra or Samsung EVO Plus, stock varies by capacity) Skip the slow, unreliable storage that comes bundled with budget handhelds — these are genuine, name-brand microSD cards built for fast, reliable performance in handhelds, Steam Deck, and Android emulation devices alike. UHS-I rated with A1/A2 app performance, they deliver read speeds up to 100–160MB/s depending on capacity, so load times stay fast and gameplay stays stutter-free even on larger game libraries.

Available in SanDisk Ultra or Samsung EVO Plus, depending on current stock — both are genuine, authenticated retail cards, not the unbranded or counterfeit cards that show up cheap on some marketplaces (a real risk category with handheld accessories, since fake high-capacity cards are common).

Capacity guide:

• 128GB — solid choice for a single handheld's full game library plus saves

• 256GB — our most popular size, comfortable headroom for multiple emulated systems

• 512GB — built for power users running heavier systems (PS2/Dreamcast-era) or multiple handhelds
  

What's in the box: MicroSD card, full-size SD adapter.

Why it's a NexonWorld favourite: The unglamorous upgrade that actually matters most — a slow or unreliable card is the single biggest cause of stuttering and crashes on emulation handhelds, and this fixes that permanently.

A flag on this one specifically: unlike the handheld products, storage cards by themselves are completely neutral — no ROM-distribution concerns here, since you're selling blank, brand-certified capacity, not content. Good one to lean into for trust messaging if you want a "buy genuine, avoid counterfeits" angle on the product page.
