Lenovo is making a big splash in the world of Steam Deck alternatives with the Lenovo Legion Go. This new handheld offers a much bigger screen with a higher resolution and refresh rate than its high-profile competitors like the Asus ROG Ally and Steam Deck. It also has detachable controllers, similar to the Nintendo Switch.

Out of the box, the Lenovo Legion Go can be configured with up to 1TB of SSD storage, which is already solid, but what if you opt for a cheaper model at launch and want to upgrade later down the line? Thankfully, you can upgrade the storage, but with a caveat. Lenovo is using a different size for its SSDs, coming in an M.2 2242 form factor compared to the M.2 2230 size of Steam Deck SSDs, so finding a replacement is a bit harder. Still, we've picked out a few great SSD options for you.

  • Fantom Drives eXtreme Thunderbolt 3 SSD

    Plug and play

    Internal SSDs may seem like the most logical choice, but you can always upgrade the storage on your Lenovo Legion Go with an external SSD. The Fantom Drives Extreme uses Thunderbolt 3 or USB4 to support speeds up to 2,800MB/s, which means it's very fast and requires much less hassle.

  • TEKQ Rapide

    If you want an external SSD that you can upgrade later on, this TEKQ SSD enclosure does just that. It fits an M.2 2280 SSD, and these models are much easier to find, which makes upgrading far easier. Plus, it has pretty fast speeds.

Best SSDs for Lenovo Legion Go: Final thoughts

Being restricted to the M.2 2242 form factor makes it a bit harder to find a good SSD for the Lenovo Legion Go, but luckily, there are quite a few options out there. One thing to keep in mind is that some SSDs have chips on both sides for bigger capacities, and these dual-sided SSDs may not fit in every device.

Either way, the Lenovo ThinkBook PCIe 3.0 SSD is a great option for the vast majority of users, offering great speeds and capacity at a solid price and coming from a reliable brand. If you want to save more money, the VisionTek PCIe 4.0 SSD may be just right for you, providing plenty of performance at a reasonable price.
