microSD cards are convenient, but external SSDs are faster, more reliable, and can hold your entire library without swapping. We tested the best portable SSDs for handheld gaming — focusing on speed, durability, and how well they actually sit next to your Switch or Steam Deck without dangling awkwardly.
If you've ever waited through a loading screen on your Steam Deck or watched a Switch game stutter, you know the problem isn't the console — it's the storage. microSD cards are fine for archiving, but they're slow. External SSDs, especially ones using NVMe and USB 3.2 Gen 2 or Gen 2x2, offer dramatically faster read and write speeds.1 That means shorter load times, smoother texture streaming, and less time staring at progress bars.
But not every external SSD works well with handhelds. Size matters — a bulky drive dangling off a USB-C port is annoying. Durability matters — these things get tossed in bags. And speed matters — you want USB 3.2 Gen 2 at minimum.
Here are the best external SSDs for your Nintendo Switch and Steam Deck right now.
The SanDisk Extreme Portable hits the sweet spot. It's small, rugged, and fast enough for any game you throw at it. With read speeds up to 1,050 MB/s and a USB 3.2 Gen 2 interface, it'll cut your load times noticeably compared to even the best microSD cards.1 It's IP65-rated for dust and water resistance, so tossing it in a backpack with your Steam Deck isn't a worry. And it's compact enough that it won't dangle awkwardly from your console — it sits flat next to it.
If you want the absolute fastest transfer speeds and don't mind paying a premium, the SanDisk Creator or Pro-series drives push into USB 3.2 Gen 2x2 territory, hitting up to 2,000 MB/s.1 That's overkill for most games today, but if you're also moving large game installs between a PC and your handheld, the time savings add up. These drives are slightly larger than the Extreme but still portable enough for travel.
The ZIKE Magnetic SSD is the most compact option here — it's designed to stick onto the back of an iPhone, but its tiny footprint and USB-C connectivity make it a surprisingly good fit for handheld gaming too. It won't match the raw speed of the SanDisk drives, but if your priority is keeping things tidy and not having a drive flopping around, this is the neatest solution. Just note it's not as rugged as the others, so treat it gently.
| Pick | Speed | Durability | Size |
|---|---|---|---|
| SanDisk Extreme Portable | 1,050 MB/s (Gen 2) | IP65 | Compact |
| SanDisk Creator/Pro | 2,000 MB/s (Gen 2x2) | Standard | Medium |
| ZIKE Magnetic SSD | ~1,000 MB/s (Gen 2) | None | Ultra-compact |
We focused on three things: portability (will it dangle awkwardly or sit neatly?), speed (will it actually reduce load times?), and durability (will it survive a backpack?). The SanDisk Extreme Portable wins on all three fronts. The Creator/Pro is for speed demons. The ZIKE is for minimalists who hate clutter.
