Frequently Asked Questions (FAQ)
Q1: Why do I need an external SSD for my Steam Deck?
A1: The Steam Deck’s internal storage can fill up quickly, especially with modern AAA games. An external SSD provides significantly more storage space, allowing you to carry a larger game library. It also offers much faster read/write speeds than a typical microSD card, leading to quicker game loading times and smoother gameplay.
Q2: Can I play games directly from an external SSD on my Steam Deck?
A2: Yes, absolutely! You can install games directly onto an external SSD and play them from there. This is one of the primary reasons to get one, as it expands your playable library without filling up the internal drive.
Q3: What’s the difference between an external SSD and a microSD card for Steam Deck?
A3: External SSDs generally offer much faster transfer speeds than microSD cards, which translates to quicker game loading and installation times. SSDs are also typically more durable and reliable. MicroSD cards, while convenient and compact, are usually slower and better suited for smaller games or less frequently accessed media.
Q4: How do I connect an external SSD to my Steam Deck?
A4: Most external SSDs connect to the Steam Deck via its USB-C port. You might need a USB-C hub if you want to connect other peripherals (like a charger or external display) simultaneously, as the Steam Deck only has one USB-C port. Ensure your SSD comes with a USB-C cable or an adapter.
Q5: What file format should my external SSD be for Steam Deck?
A5: For maximum compatibility across different operating systems (including SteamOS, Windows, and macOS), it’s best to format your external SSD to exFAT. This format allows for large file sizes and is generally plug-and-play friendly. SteamOS (Linux-based) can also read other formats like ext4, but exFAT is the most universally accessible.
Q6: Will using an external SSD affect my Steam Deck’s battery life?
A6: Yes, connecting any external device to your Steam Deck will draw some power, which can slightly impact battery life. However, modern external SSDs are generally power-efficient, so the impact is often minimal, especially compared to the convenience and performance boost they offer.
Q7: What speed should I look for in an external SSD for my Steam Deck?
A7: Look for SSDs with transfer speeds of at least 500MB/s, but ideally 1000MB/s (1GB/s) or more. Speeds around 1050MB/s are common for USB 3.2 Gen 2 (10Gbps) drives and offer a great balance of performance and value. Faster drives (20Gbps or Gen4 NVMe) exist but may be overkill or require specific setups to fully utilize their speed.
