Why Upgrade Your ROG Ally SSD?
Still on the fence about upgrading your ROG Ally’s storage? Here’s why it’s one of the best enhancements you can make:
- Massive Game Library: Say goodbye to constantly uninstalling games. With 1TB or 2TB of internal storage, you can keep dozens of your favorite AAA titles ready to play at a moment’s notice.
- Blazing-Fast Load Times: PCIe Gen4 NVMe SSDs dramatically reduce game loading screens, boot times, and application launches. More gaming, less waiting!
- Smoother Performance: A faster SSD improves overall system responsiveness, especially when dealing with large game files or multiple applications.
- No More MicroSD Woes: While microSD cards are convenient, they simply can’t match the speed and reliability of an internal NVMe SSD, especially for demanding games.
Choosing the Right SSD for Your ROG Ally
When looking for the best SSD for ROG Ally, keep these factors in mind:
- Form Factor is King: M.2 2230: The ROG Ally uses a very specific M.2 2230 form factor for its internal SSD slot. Make sure any drive you purchase is this size for a direct, hassle-free installation. As we saw with the Lexar NM790, a 2280 drive can be used with an adapter, but it adds complexity and may not be ideal.
- PCIe Gen4 Speeds: The ROG Ally supports PCIe Gen4, so opting for a Gen4 NVMe SSD will give you the fastest possible performance for game loading and data transfer. Don’t settle for slower Gen3 if you want the absolute best experience.
- Capacity: 1TB is a fantastic upgrade over the base 512GB and offers plenty of space for many gamers. If you have a massive library or want to future-proof, 2TB is the ultimate choice.
- Reliability and Warranty: Look for reputable brands and drives with a solid warranty (5 years is great) and a good Total Bytes Written (TBW) rating, which indicates how much data can be written to the drive over its lifetime.
Conclusion
Upgrading your ASUS ROG Ally’s SSD is arguably the best single modification you can make to enhance your gaming experience. Whether you’re after a massive 2TB capacity to hold your entire game library, or the absolute fastest speeds to cut down on load times, there’s an option here for you. While finding the Lexar best SSD for ROG Ally from our list requires a consideration of form factor (as the NM790 is 2280), the other M.2 2230 options like Sabrent, fanxiang, and Addlink offer direct, high-performance upgrades.
No matter which SSD you choose, you’re in for a significant boost in storage and speed, making your ROG Ally an even more formidable portable gaming machine. Happy gaming!
FAQ Section
Q1: Why do I need an M.2 2230 SSD for my ROG Ally?
A1: The ROG Ally’s internal SSD slot is specifically designed for the M.2 2230 form factor. This small size is necessary to fit within the handheld’s compact chassis. Using any other size (like a 2242 or 2280) would require an adapter or simply wouldn’t fit, adding complications.
Q2: Is upgrading the ROG Ally SSD difficult?
A2: For those comfortable with basic electronics work, it’s generally a manageable process. It involves opening the device, removing a few screws, and carefully swapping the SSD. There are many helpful video tutorials online that can guide you step-by-step. However, if you’re not confident, it’s best to seek professional help.
Q3: Will upgrading my SSD void my ROG Ally’s warranty?
A3: ASUS’s warranty policy states that opening the device itself does not automatically void the warranty, provided no damage occurs during the process. However, if any damage is caused during the upgrade, that specific damage would not be covered. Always proceed with caution.
Q4: What’s the difference between PCIe Gen3 and Gen4 SSDs for the ROG Ally?
A4: PCIe Gen4 SSDs offer significantly faster read and write speeds compared to Gen3 drives. Since the ROG Ally supports PCIe Gen4, installing a Gen4 SSD will maximize your loading times and overall system responsiveness for games and applications. Gen3 drives will still work but won’t be as fast.
Q5: How do I transfer my old data to the new SSD?
A5: You’ll typically need to “clone” your old SSD to the new one. This involves using cloning software (some SSDs, like Sabrent, include this) and a USB NVMe enclosure for the new drive. Once cloned, you simply swap the drives, and your ROG Ally should boot up exactly as it did before, but with more space. Alternatively, you can perform a fresh Windows installation on the new SSD.
Q6: Do I need a heatsink for my ROG Ally SSD?
A6: Most 2230 NVMe SSDs designed for handhelds often come with or are designed to function well without large heatsinks, especially since space is extremely limited inside the ROG Ally. Drives like the fanxiang S630 even include a thin graphene sticker for heat dissipation. While a dedicated large heatsink isn’t usually an option, ensuring the drive you pick has good thermal management is beneficial for sustained performance.
Q7: Can I use a 2280 SSD in my ROG Ally?
A7: No, not directly. The ROG Ally uses an M.2 2230 slot. While you can find adapter boards (e.g., 2230 to 2280) that might allow you to physically connect a 2280 SSD, this is a more complex solution that may not fit perfectly or consistently, and could potentially interfere with cooling or other components. For a straightforward and reliable upgrade, sticking to M.2 2230 drives is highly recommended.
