Hey there, fellow gamers! If you’re rocking the ASUS ROG Ally, you already know it’s a fantastic piece of portable gaming tech. But let’s be real, the stock storage can feel a bit cramped, especially with those massive game installs. Upgrading your SSD isn’t just about getting more space; it’s about making your Ally even snappier, loading games faster, and carrying your entire game library wherever you go.
But with so many options out there, how do you pick the best SSD for ROG Ally? Don’t sweat it! We’ve done the digging for you. In this guide, we’ll walk you through what to look for and highlight our top picks to give your ASUS ROG Ally the storage boost it deserves.
Why Upgrade Your ROG Ally’s SSD?
The ASUS ROG Ally typically comes with a 512GB M.2 2230 NVMe SSD. While that’s decent, modern AAA games can easily chew up 100GB or more each. An upgrade means:
- More Games: Install more of your favorite titles without constant uninstalling.
- Faster Loading Times: Experience quicker boot-ups and in-game loading thanks to cutting-edge NVMe speeds.
- Better Performance: A high-quality SSD can contribute to smoother overall system responsiveness.
- Future-Proofing: Prepare for even larger games coming down the pipeline.
Key Considerations When Choosing an SSD for Your ROG Ally
Before you dive in, here’s what to keep in mind:
- Form Factor (M.2 2230): This is crucial! The ROG Ally uses a compact 2230 size SSD (22mm wide, 30mm long). Most desktop SSDs are 2280, which won’t fit without an adapter.
- Interface (PCIe Gen4): Your Ally supports PCIe Gen4, so look for a Gen4 drive to get the best speeds. While Gen3 will work, it won’t be as fast.
- Capacity: 1TB or 2TB are popular choices, but some adventurous folks go even higher if using an adapter.
- Speed (Read/Write): Look for high sequential read/write speeds, especially for gaming.
- Reliability & Brand Reputation: Stick with reputable brands known for quality and good warranties.
Now, let’s get to the good stuff – our top picks for the best SSD for ROG Ally!

Frequently Asked Questions (FAQ)
Q1: Is it hard to upgrade the SSD in the ROG Ally?
A1: Upgrading the SSD in the ROG Ally is generally considered a moderate difficulty task. It requires opening the device, disconnecting the battery, and carefully removing and installing the new M.2 2230 SSD. If you opt for a 2280 adapter, the process becomes more complex. Many video tutorials are available online to guide you through it.
Q2: Will upgrading my SSD void my ROG Ally’s warranty?
A2: Officially, opening your ROG Ally to upgrade components could potentially void your warranty if damage occurs during the process or if the new component causes issues. However, many manufacturers (including ASUS in some regions) have a “right to repair” stance, meaning basic upgrades like an SSD might not void it unless direct damage is caused. Always check your local warranty terms or consult ASUS support.
Q3: Can I use a 2280 SSD directly in the ROG Ally?
A3: No, the ROG Ally natively supports only the shorter 2230 M.2 NVMe SSDs. To use a larger 2280 SSD, you will need a special 2230 to 2280 adapter board, which requires more advanced installation and can sometimes impact thermals or fit.
Q4: Do I need to reinstall Windows after upgrading the SSD?
A4: Not necessarily! You can “clone” your existing operating system and data from your old SSD to the new one using disk cloning software (some SSDs, like Sabrent, even include this software). This saves you from having to reinstall Windows and all your applications from scratch.
Q5: What’s the difference between QLC and TLC NAND flash?
A5: QLC (Quad-Level Cell) and TLC (Triple-Level Cell) refer to how much data each memory cell can store. TLC stores 3 bits per cell, while QLC stores 4. QLC typically allows for higher capacities at a lower cost but can be slightly slower for sustained heavy writes and has a lower endurance rating compared to TLC. For gaming and general use, QLC is usually perfectly fine.
Q6: Does a faster SSD improve game performance (FPS)?
A6: A faster SSD primarily improves game loading times, level transitions, and overall system responsiveness. It generally does not directly increase your in-game frames per second (FPS), as FPS is more dependent on the CPU, GPU, and RAM. However, eliminating storage bottlenecks can lead to a smoother gaming experience.
Q7: Is a 1TB or 2TB SSD better for the ROG Ally?
A7: This depends on your game library size. For most users, a 1TB SSD is a solid upgrade, offering double the stock storage. However, if you play a lot of large AAA games or want to install a vast library without constantly managing space, a 2TB SSD is highly recommended and often considered the sweet spot for the best SSD for ROG Ally experience.
Final Thoughts on the Best SSD for ROG Ally
Upgrading your ASUS ROG Ally’s storage is one of the best improvements you can make to your handheld gaming experience. Whether you go for a direct-fit 2230 drive like the Sabrent Rocket Q4 or Crucial P310 for simplicity and excellent performance, or brave the adapter route for massive capacities with a WD_BLACK SN7100, you’re in for a treat.
Remember to choose the drive that best fits your needs, budget, and comfort level with the installation process. Happy gaming, and enjoy your expanded game library!
