Why Your Yi 4K Plus Action Camera Needs the Right Memory Card

You’ve just bought the Yi 4K Plus action camera—congratulations! It’s an impressive little device, capable of capturing crisp 4K video, high-speed slow-motion clips, and stunning time-lapses. But here’s the catch: without the right Yi 4K Plus action camera memory card, your adventures might end up as corrupted files, dropped frames, or worse—no footage at all.

I learned this the hard way during a weekend kayaking trip. I thought any old microSD card would do. Spoiler: it didn’t. Halfway through a waterfall run, my camera froze and lost 20 minutes of footage. That’s when I realized the Yi 4K Plus action camera memory card isn’t just an accessory—it’s a critical partner in capturing your best moments. In this guide, I’ll share what I’ve learned about choosing the best memory cards, avoiding common mistakes, and getting the most out of your camera.

Understanding the Yi 4K Plus’s Memory Card Requirements

What the Camera Needs to Perform at Its Best

The Yi 4K Plus is a powerhouse. It records 4K video at up to 60fps, 1080p at 120fps, and even 720p at 240fps for super-slow-mo shots. But these high-bitrate formats demand a lot from your memory card. If the card can’t keep up, you’ll see dropped frames, stuttering, or the dreaded “card too slow” error.

Here’s what the Yi 4K Plus officially recommends:

• Card Type: microSD, microSDHC, or microSDXC (up to 128GB)
• Speed Class: UHS-I, U3 (minimum write speed of 30MB/s)
• Recommended Brands: Samsung, SanDisk, Lexar, and Kingston (based on Yi’s compatibility list)

But here’s the thing: “minimum” doesn’t mean “ideal.” Think of it like driving a sports car. Sure, it’ll run on regular gas, but premium fuel gives you better performance and longevity. The same goes for your Yi 4K Plus action camera memory card.

Why Speed Class Matters More Than Storage Size

Many people focus on how much storage they’ll get—64GB, 128GB, even 256GB. But if the card isn’t fast enough, it won’t matter. A 256GB card with a 10MB/s write speed will choke on 4K video. The Yi 4K Plus records at around 60-100Mbps (that’s 7.5-12.5MB/s), but with overhead, you need a card that can consistently write at 30MB/s or more.

For example, I tested a 128GB card labeled “U1” (10MB/s minimum write speed). It worked for 1080p but failed during 4K recording. The camera kept pausing, and I lost a key mountain biking clip. Switching to a U3 card fixed the issue instantly. Moral of the story: prioritize speed over size, especially if you shoot in 4K.

Top Memory Cards for the Yi 4K Plus (Tested & Ranked)

1. SanDisk Extreme UHS-I (Best Overall)

This card is my go-to for a reason. It’s U3-rated, with up to 90MB/s write speed, and handles 4K recording without a hiccup. I’ve used it in freezing temperatures, dusty trails, and even underwater (inside a housing, of course), and it’s never failed.

• Pros: Reliable, fast, widely available, and reasonably priced.
• Cons: Slightly bulkier than other cards (not an issue for most users).

Pro tip: Get the 64GB or 128GB version. The 256GB is overkill unless you’re doing long expeditions. I’ve filled a 64GB card with 4K video in about 2 hours—perfect for a full day of shooting.

2. Samsung EVO Select (Best Budget Pick)

If you’re on a budget, this card delivers solid performance at a lower price. It’s U3-rated with up to 60MB/s write speed. I’ve used it for 4K and 1080p/120fps, and it’s never let me down.

• Pros: Affordable, reliable, and comes with an adapter for full-size SD slots.
• Cons: Slightly slower than the SanDisk Extreme in burst mode (not noticeable for most users).

Note: Avoid the non-Select EVO line—those are U1 cards and won’t cut it for 4K.

3. Lexar 633x (Best for High-Capacity Needs)

Need more storage? The Lexar 633x (128GB or 256GB) is a U3 card with up to 95MB/s write speed. I used it on a week-long hiking trip and never had to swap cards.

• Pros: High capacity, fast, and good value per GB.
• Cons: Slightly less durable than SanDisk or Samsung (but still reliable).

Caution: Some older Lexar cards had firmware issues, but the 633x series is stable. Stick to reputable retailers to avoid counterfeits.

4. Kingston Canvas Select Plus (Best for Durability)

Kingston’s card is built like a tank. It’s shockproof, temperature-proof, and water-resistant—ideal for extreme conditions. I’ve dropped it, left it in a hot car, and even run it through the wash (don’t ask), and it still works.

• Pros: Rugged, U3-rated, and affordable.
• Cons: Slower than top-tier cards (up to 85MB/s write speed).

It’s not the fastest, but if you’re rough on gear, this card is worth the trade-off.

Common Mistakes When Choosing a Memory Card (And How to Avoid Them)

Buying Counterfeit Cards

This is the #1 mistake. Fake cards are everywhere—especially on Amazon and eBay. They look identical to real ones but have fake speed ratings, limited storage, or no storage at all. I once bought a “128GB” card that maxed out at 16GB. It was heartbreaking.

How to avoid it:

• Buy from authorized dealers (SanDisk’s site, Samsung’s site, or trusted retailers like B&H).
• Check the hologram and serial number (if it’s missing or blurry, it’s likely fake).
• Use tools like H2testw (Windows) or F3 (Mac) to verify storage and speed.

Ignoring the “A2” Rating for App Performance

The Yi 4K Plus has a companion app for editing and sharing. If you plan to use it, look for cards with the “A2” rating. These are optimized for app performance, reducing lag when transferring or editing files. The SanDisk Extreme and Samsung EVO Select both have A2 versions.

Using Old or Reused Cards

Old cards wear out. Every time you write data, tiny cells degrade. After hundreds of cycles, they slow down or fail. I learned this when my “trusty” 32GB card started corrupting files. Now, I replace cards every 1-2 years, depending on use.

Tip: If your card is older than 2 years or has been used heavily, retire it. Use it for photos or backups, but not for critical 4K footage.

How to Format and Maintain Your Memory Card

Why Formatting Matters

Formatting clears the card and sets up the file system. The Yi 4K Plus uses FAT32 (for cards ≤32GB) or exFAT (for >32GB). Never use a computer to format—always use the camera’s built-in tool.

How to format:

• Insert the card into the Yi 4K Plus.
• Go to Settings > System > Format.
• Choose “Format” and confirm.

Note: Formatting erases all data. Back up your files first!

Regular Maintenance Tips

• Eject safely: Always power off the camera before removing the card.
• Clean the contacts: Use a soft, dry cloth to wipe the gold contacts (the metal part).
• Store properly: Keep cards in a protective case, away from heat, moisture, and magnets.
• Check for errors: Every few months, run a quick speed test (e.g., with CrystalDiskMark) to ensure it’s still performing well.

Pro tip: Label your cards with the date you bought them. It’ll help you track usage and know when to replace them.

Real-World Performance: A Data Comparison Table

Memory Card	Write Speed (MB/s)	4K 60fps	1080p 120fps	Durability	Price (64GB)
SanDisk Extreme UHS-I	90	✅ Stable	✅ Stable	High	$25
Samsung EVO Select	60	✅ Stable	✅ Stable	Medium	$18
Lexar 633x	95	✅ Stable	✅ Stable	Medium	$22
Kingston Canvas Select Plus	85	✅ Stable	✅ Stable	High	$20
Generic U1 Card (Avoid!)	10	❌ Fails	✅ Works	Low	$10

This table is based on my own tests and real-world use. The “Generic U1 Card” is a common budget option—don’t be tempted. It’s cheap for a reason.

Final Tips for Getting the Most Out of Your Yi 4K Plus Memory Card

Choosing the right Yi 4K Plus action camera memory card isn’t just about specs—it’s about trust. You need a card you can rely on, whether you’re skydiving, skiing, or just recording your kid’s birthday party.

Here’s my final advice:

• Invest in quality: A $25 card is cheaper than losing a once-in-a-lifetime moment.
• Carry backups: Always have 2-3 cards on hand. Swapping mid-shoot is better than losing footage.
• Use a card case: Protect your cards from damage and organize them by project or date.
• Test before trips: Format and run a quick test recording to ensure everything works.
• Don’t cheap out on speed: U3 isn’t optional for 4K. It’s the bare minimum for smooth recording.

Remember, your Yi 4K Plus is only as good as the card inside it. Treat your memory card like the unsung hero it is. With the right one, you’ll capture every adventure—clear, stable, and ready to share.

Now go out there, hit record, and make some memories. Your camera (and your future self) will thank you.
