The world of Steam Deck alternatives is always expanding these days, and Lenovo is one of the biggest players to join the fray with the Legion Go. This is one of the biggest and most versatile gaming handhelds around, with a large 8.8-inch display and removable controllers much like Nintendo's Joy-Con, making it more flexible than the Steam Deck or the Asus ROG Ally.

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.

  • Editor's choice
    Corsair MP600 Micro

    The Corsair MP600 Micro is a top-tier SSD from a well-known company, and it offers excellent speeds, reaching up to a whopping 5,100MB/s thanks to the PCIe 4.0 interface. The M.2 2242 form factor makes it a perfect fit for the Lenovo Legion Go.

  • Premium pick
    Lenovo ThinkPad PCIe 4 M.2 2242 SSD
    $215 $240 Save $25

    Want faster storage? Lenovo also makes this ThinkPad branded PCIe 4.0 SSD that fits the Legion Go. It has a larger capacity and should give you much faster speeds, too. It does come at a much higher price, though.

  • Best value
    VisionTek DLX4 M.2 2242 SSD
    $66 $85 Save $19

    If you're looking to save a buck, the VisioNTek DLX4 is one of the best SSDs you can get. It still supports PCIe 4.0, but it's far more affordable and comes in a few different size options for different budgets.

  • Great value alternative
    Inland TN325 M.2 2242 SSD

    Another great option for a cheaper PCIe 3.0 SSD is this one from Inland. It comes in capacities up to 2TB, and even the largest model costs just $170, making it a great deal.

  • Super fast
    KingSpec XG7000 M.2 2242 SSD

    Most small SSDs have lower speeds than their large M.2 2280 form factor, but the KingSpec XG7000 promises incredible speeds up to 7,200MB/s, even at this smaller size. It's super fast and it comes from a relatively well-known brand, making it a good bet if you need the best speeds.

  • More storage for less
    Timetec NVMe PCIe SSD

    If you want a cheap way to add storage to your Lenovo Legion Go, this Timetec SSD maybe be the most affordable option around. With PCIe 3.0 speeds, it won't be as fast as other alternatives, but it costs just $64 for a 1TB model, which you won't find anywhere else.

  • Plug and play
    Fantom Drives Extreme

    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.

  • External but upgradeable
    TEKQ SuperVeloce SSD

    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 still some great options here. 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.

Regardless, the Corsair MP600 Micro is the best option around, offering top-tier speeds and coming from a reliable and reputable brand, all while coming in at a reasonable price. There are cheaper options, but you have to sacrifice performance for that reduction in price.
