FAQ Section
Q1: Why do I need a 2230 SSD for my ROG Ally?
A1: The ASUS ROG Ally, like the Steam Deck and many Microsoft Surface devices, uses the compact M.2 2230 form factor for its internal SSD. This small size is crucial for fitting into the device’s limited space. Upgrading ensures you get more storage and faster speeds for your games and applications.
Q2: Is it difficult to install a 2230 SSD in the ROG Ally?
A2: For those comfortable with basic electronics work, it’s generally a straightforward process. You’ll need a small screwdriver, a pry tool (optional), and patience. There are many excellent video tutorials online that guide you step-by-step. However, if you’re unsure, it’s always best to seek professional help to avoid damaging your device.
Q3: What capacity should I choose for my ROG Ally?
A3: Most users find 1TB or 2TB to be the sweet spot. The ROG Ally typically comes with 512GB, which fills up quickly. A 1TB drive offers a significant upgrade, allowing you to install many AAA games. A 2TB drive provides even more headroom, practically eliminating the need to manage your game library constantly.
Q4: What’s the difference between PCIe Gen3 and Gen4? Does it matter for the ROG Ally?
A4: PCIe Gen4 (PCIe 4.0) offers roughly double the theoretical bandwidth of PCIe Gen3 (PCIe 3.0). The ROG Ally supports PCIe Gen4 speeds, so choosing a Gen4 SSD will give you the fastest possible load times and overall performance. While Gen3 SSDs are compatible, they will be limited to Gen3 speeds. For the best experience, a Gen4 drive is recommended.
Q5: Can I use a 2242 or 2280 SSD in my ROG Ally?
A5: No, the ASUS ROG Ally is specifically designed for the M.2 2230 form factor. Larger SSDs like 2242 (22mm wide, 42mm long) or 2280 (22mm wide, 80mm long) will not physically fit inside the device. Always double-check the form factor before purchasing an SSD.
Q6: Does Lexar make a good 2230 SSD for the ROG Ally?
A6: Yes, Lexar is a reputable brand that offers high-quality storage solutions, including M.2 2230 NVMe SSDs that are perfectly compatible with the ROG Ally. Their drives often boast excellent performance and reliability, making them a popular choice among users. This article highlighted other strong contenders, but Lexar remains a solid option.
Q7: Should I worry about heat with a new 2230 SSD in my ROG Ally?
A7: Handheld devices have limited airflow, so heat can be a concern. Modern 2230 NVMe SSDs are designed to operate efficiently, but intense usage can generate heat. Some SSDs, like the fanxiang models reviewed, include graphene heatsinks to help. Generally, most quality 2230 NVMe SSDs manage thermals well enough for typical handheld gaming without causing issues, but it’s always good to check user reviews regarding prolonged heavy use.
