The ASUS ROG Ally is a powerful handheld gaming PC, but whether you have the original model or the new ROG Ally X, storage space can quickly become a premium. With modern AAA titles often exceeding 100GB, that 512GB or 1TB drive fills up fast .
When you need more space, you have two main options: upgrading the internal SSD or simply popping in a MicroSD card. But which path should you take? The answer depends on your priorities for speed, safety, budget, and technical confidence. Let's break down the ultimate showdown between the SSD upgrade and the MicroSD card for your ROG Ally.
The Contenders at a Glance
- SSD Upgrade: Replacing the internal NVMe drive for massive, super-fast storage.
- MicroSD Card: Expanding storage via the external slot for easy, low-cost capacity.
Speed and Performance
Winner: SSD Upgrade (A Decisive Knockout)
If you crave the fastest possible load times and the smoothest performance in open-world games, there is no contest.
- SSD Speed: Upgrading your internal SSD delivers a massive performance leap. Modern drives like the XG7000 2280 can achieve blistering read speeds of up to 7,000 MB/s on the PCIe Gen4 interface . Even a more power-efficient drive like the XF-2230 offers exceptional random read performance, which is crucial for game loading and texture streaming . This means games launch faster, levels load in the blink of an eye, and you'll experience less pop-in as you explore detailed worlds
-
MicroSD Speed: While convenient, MicroSD cards are significantly slower. The ROG Ally line features a UHS-II card reader, which is capable of faster speeds . However, even the best cards are playing catch-up.
- Standard UHS-I cards typically top out around 110 MB/s to 175 MB/s .
While 175 MB/s is respectable, it's still less than 4% of the speed of a top-tier SSD. For less demanding indie games, a MicroSD is fine, but for the latest and greatest AAA titles, the SSD's speed is a game-changer.
Safety and the "MicroSD Problem"
Winner: SSD Upgrade (for original ROG Ally), Tie (for ROG Ally X)
This round is heavily dependent on which model you own.
- The Original ROG Ally (RC71): Early models of the original ROG Ally had a well-documented design flaw. The MicroSD card reader was located directly next to a heat exhaust vent . Under heavy load, the heat could cause the reader to malfunction and, in some tragic cases, even physically damage MicroSD cards . While ASUS released firmware updates to manage fan curves and mitigate the issue, the risk is a lingering concern for original Ally owners. If you have this model, relying on a MicroSD for your primary game library is a gamble.
- The ROG Ally X (RC72) and Newer Models: ASUS listened to the feedback. On the Ally X and the new ROG Xbox Ally models, the MicroSD slot has been relocated away from the exhaust vent . The cooling system has also been beefed up, making it much safer to use a MicroSD card without fear of thermal damage.
- SSD Safety: An internal SSD is safely tucked inside the chassis, away from direct heat sources and physical damage. It's the more robust and reliable option for any model.
Ease of Installation and Convenience
Winner: MicroSD Card (A Total Pushover)
If you want to add storage in seconds without any tools or technical know-how, the MicroSD card is the undisputed champion.
- MicroSD Convenience: You buy a card, you push it into the slot until it clicks, and you're done. You just need to format it to NTFS in Windows for the Ally to recognize it properly . That's it. You can even swap cards to carry different game libraries with you.
- SSD Installation: Upgrading an SSD requires courage and a screwdriver. It's not overly complex, but it does involve:
While doable for many, it's a process that voids your warranty if you break something and requires a bit of patience .
Cost and Capacity
Winner: MicroSD Card (For low-cost expansion), SSD Upgrade (For max capacity)
This round is a split decision.
- Upfront Cost: MicroSD cards are the clear winner for a quick, cheap boost. A high-capacity card is a relatively small investment. For example, a fast 1TB MicroSD card is generally cheaper than a high-performance 1TB 2230 SSD, which carries a premium for its compact size.
- Maximum Capacity: If money is no object and you want the absolute largest storage possible, the SSD wins. With an SSD upgrade, you can install a 2TB drive in the original Ally . For the Ally X and newer models, which support the standard 2280 size, the sky is the limit. You can install drives like the XG7000 2280 up to a massive 8TB .
