Frequently Asked Questions (FAQ)
Q1: Is an external SSD truly better than a microSD card for the Steam Deck?
A1: Absolutely! While microSD cards are convenient, external SSDs offer significantly faster read and write speeds (often 5-10 times faster than even the best A2-rated microSD cards). This translates to much quicker game loading times, faster game transfers, and an overall smoother gaming experience for your Steam Deck.
Q2: How do I connect a Lexar external SSD to my Steam Deck?
A2: Connecting is straightforward! Most Lexar external SSDs come with a USB-C to USB-C cable (or a 2-in-1 USB-C/USB-A cable). Simply plug the USB-C end into your Steam Deck’s USB-C port. You might need to format the drive on your Steam Deck or PC before use, but the Steam Deck typically guides you through this.
Q3: Will using an external SSD drain my Steam Deck’s battery faster?
A3: Any connected peripheral will draw some power. However, modern external SSDs are quite power-efficient. The impact on battery life from a Lexar external SSD is generally minimal and outweighed by the benefits of expanded, faster storage. If you’re concerned, you can always connect the SSD through a powered USB-C hub.
Q4: Can I install my Steam Deck games directly onto the external SSD?
A4: Yes, absolutely! Once your Lexar external SSD is connected and recognized by your Steam Deck, you can set it as a new Steam Library folder. When downloading or installing games, you’ll be prompted to choose where to install them, and you can select your external SSD.
Q5: What’s the difference between USB 3.2 Gen 2 and USB 3.2 Gen 2×2, and how does it affect my Steam Deck?
A5: USB 3.2 Gen 2 offers speeds up to 10Gbps (around 1000MB/s), while USB 3.2 Gen 2×2 can reach up to 20Gbps (around 2000MB/s). The Steam Deck’s USB-C port supports USB 3.2 Gen 2. This means even if your external SSD supports Gen 2×2 (like the ES5 series), it will operate at the Steam Deck’s maximum Gen 2 speed, which is still incredibly fast and more than enough for excellent gaming performance.
Q6: Should I get a 1TB or 2TB (or even 4TB) external SSD for my Steam Deck?
A6: This depends on your game library size and budget.
* 1TB is great for a solid expansion, holding numerous AAA titles.
* 2TB offers more breathing room, letting you keep a massive collection installed without worrying about space.
* 4TB is for hardcore gamers with huge libraries or those who want to future-proof their storage for years to come (especially if considering something like an NVMe in an enclosure). Consider how many large games you play regularly.
Q7: Are Lexar external SSDs durable enough for travel and portable use?
A7: Yes! Lexar SSDs, especially models like the ES3 and ES5, are designed with durability in mind. Features like drop resistance, metal casings, and even IP-rated water/dust protection (on the ES5) ensure they can withstand the bumps and scrapes of being carried around with your Steam Deck. They’re built for on-the-go life.
