【Ace Pro 2 SD Card】Insta360 Ace Pro 2 SD Card Buying Guide: Capacity, Speed, and Recommended Brands

Based on user reviews from the official Insta360 website, many Ace Pro 2 owners feel uncertain about which microSD card capacity to choose. In this guide, we’ll recommend the best memory cards for both the Ace Pro and Ace Pro 2, so you can find the ideal option quickly and confidently.

Let me get right to the point, Insta360 officially recommends 128GB as the best SD card capacity, and I personally find this capacity to be the most practical. In this article, I'm going to explain why I recommend getting a 128GB SD card when using the Ace Pro 2.

Recommended MicroSD Card Specifications for Insta360 Ace Pro and Ace Pro 2

I most recommend usingSanDisk Extreme series oorSD memory cards officially sold by Insta360.The

It’s worth noting that SanDisk SD cards come in three product lines, ranging from entry-level to high-end: Ultra, Extreme, and Extreme PRO.

The SanDisk Extreme series (V30/U3 speed class) is ideal for most shooting scenarios. It delivers UHS-I maximum transfer speeds (note: UHS-II/UHS-III are unnecessary) with a V30 or higher video speed rating.

To ensure optimal performance for the Insta360 Ace/Insta360 Ace Pro, you should use a UHS-I Micro SD card with a speed class of V30 or higher, formatted in exFAT. Otherwise, recording may stop, and footage may be corrupted by incompatible Micro SD cards. Note: Do not use UHS-II, UHS-III Micro SD/TF cards or Micro SD cards larger than 1TB. These cards are not supported and may cause recording failures.

Simply put, if the card's write speed is not fast enough, the data is likely to fail when shooting at 8K or 120fps. Therefore, it is important to follow the official recommendation to purchase a memory card.

In the Insta360 online manual, it says The following Sandisk SD memory cards work with the Ace Pro/Ace Pro 2.

SD Memory Card Capacity -- Which capacity should I choose from 64~512GB?

The Ace Pro/Ace Pro 2 can be used with four SD memory cards ranging from 64GB to 512GB. Below is a table that summarizes the amount of time that can be captured with each type of SD card for your convenience. As you can see, if you choose a card with less storage space, you will be limited in the amount of time you can shoot, so we recommend that you choose the card according to your shooting habits.

Recommended Camera Settings - 4K60fps

I personally use 4K60fps most often, because 4K60fps is a great setting for vlogging and shooting all kinds of sports scenes. 60fps is much smoother than 30fps.

Storage Capacity Details (128GB card): • 4K30fps: 2h33m recording time • 4K60fps: 2h8m recording time (Note: Marginal 25-minute difference between formats)

Ace Pro and Ace Pro 2 can shoot 2x slow motion.Setting it to 60fps also ensures better video quality.The

The Ace Pro and Ace Pro 2 support 8K recording, but require a high-end CPU for smooth PC editing - otherwise, editing performance will inevitably suffer. In my experience, 4K footage is the most efficient for post-production editing. That said, 8K capability isn't without merit - it maintains pristine quality even when using 2x digital zoom on Ace Pro/Ace Pro 2.

64GB microSD card

Recording Capacity vs Battery Life (64GB card): • 4K60fps: 1 hour 3 minutes recording time • 4K30fps: 1 hour 16 minutes (76 minutes) Note: Ace Pro 2's total battery life lasts 100 minutes on full charge

If you don't organize your videos on a regular basis, the storage space will quickly fill up.That's why I think 64GB is a bit insufficient.The

128GB microSD card

With a 128GB SD card, you can record continuously for over 2 hours even at 4K60fps, making 128GB undoubtedly the most practical capacity. However, if you frequently use spare batteries for extended shooting sessions, we highly recommend opting for 256GB or larger capacity SD memory cards.

Unlike 360° panoramic movies on the X4, Ace Pro and Ace Pro 2 don't need to be cut from a 360° panoramic view. Simply process the movie as is.It's also easier to perform periodic formatting than the X4The

256GB microSD card

When using a 256GB SD memory card, 4K recording can last over 4 hours, while also allowing smooth 8K video capture.

512GB microSD card

If you opt for a 512GB card, you can record up to 6 hours of 8K footage, though this capacity choice isn't particularly popular among most users. This is because cards of this size resemble SSD storage more than conventional SD cards.

How to Install an SD Memory Card in the Insta360 Ace Pro 2

The SD card slot is located adjacent to the USB port. Press firmly until you hear a "click" to ensure proper installation. To remove, gently push the card and it will automatically eject.
