SIX M200 128GB Micro SD Card Read Up to 190MB/s
Quick take
The SIX M200 is a 128GB microSDXC card aimed at high-data workloads like 4K UHD recording (V30) and faster app performance on compatible devices (A2). It also supports high-speed transfers up to 190MB/s, but that top read figure typically depends on using a DDR200 high-speed card reader or DDR200-compatible device. If you need reliable continuous recording support for action cameras, drones, or dash cams, it’s a practical option, just be sure your setup can actually realize the speed claims.
Pros and cons
Pros
- V30 rating targets sustained performance for continuous high-bitrate video recording (helps with “slow card” type errors).
- U3 support and A2 application performance can improve responsiveness on compatible Android devices and gaming handhelds.
- Rated for up to 190MB/s read speeds (with the right DDR200 reader/device).
- Comes with a card adapter for easier use in full-size SD slots.
Cons
- Reaching the advertised 190MB/s read speed usually requires a DDR200-compatible reader/device, not standard readers.
- One low-rating report mentions read issues on several platforms, so buyer-review evidence is mixed and worth considering if your priority is flawless read reliability.
- Real-world speed will vary based on your camera, drone, phone, and the specific card reader you use.
What buyers think
Buyer-review evidence is limited but points to two main themes: performance for high-bitrate use and mixed reliability signals. Several buyers describe smooth operation in cameras and drones, including steady performance during prolonged shooting, and they report a noticeable improvement versus older lower-speed cards. At the same time, there is at least one negative review alleging read problems across platforms, so the overall pattern is not perfectly one-sided. If you’re buying for continuous recording, the V30-oriented design appears to match buyer expectations more often than not, but review coverage is not extensive enough to guarantee universal reliability.
Key specs that matter for buying
Storage capacity and format
This is a 128GB microSDXC card. That capacity is a common sweet spot for action-camera workflows, dash cam loop recording (depending on bitrate), and storing a meaningful library of photos and videos without jumping all the way to larger capacities.
Video class: V30 (built for sustained recording)
The V30 video speed class is the most relevant spec for users who want to avoid dropped frames or “buffer” problems when recording continuously. V30 is designed around a minimum sustained write speed of 30MB/s, which is especially useful for high-bitrate 4K UHD recording in action cameras and similar devices.
App performance: A2 (Android and some handheld gaming use)
The card is A2-rated, which is intended to improve app-related performance on compatible devices. In practical terms, A2 can help with quicker app loading and smoother use for Android devices and some handheld consoles that support microSD app storage.
Transfer speeds: U3 and the “190MB/s” DDR200 caveat
It’s marketed with up to 190MB/s read speed and supports U3 class operation. However, the top read rate is tied to using a DDR200 high-speed card reader (sold separately) or a DDR200-compatible device. With standard readers, achievable throughput can be significantly lower, so it’s best to treat “190MB/s” as a best-case scenario for the right hardware.
Who this microSD card is best for
- Action camera, drone, and dash cam users who want a microSD card with a V30 sustained recording rating for continuous high-bitrate video capture.
- Android phone or tablet users (and handheld gaming users) looking for A2 application performance support, not just storage capacity.
- Creators who transfer files often, especially if you have a DDR200-compatible reader and want faster offloads of 4K clips.
Who should avoid it (or double-check compatibility)
- Buyers who only have a basic USB microSD reader and expect 190MB/s read speeds. Your actual transfer rate will be constrained by your reader and device.
- Anyone prioritizing confirmed, consistently flawless read reliability should weigh the mixed buyer feedback and ensure your setup supports high-speed microSDXC cards.
Pros and cons in real use
Pros, summarized
- Designed for sustained recording: V30 helps keep high-bitrate capture running smoothly over longer sessions.
- More than “just storage”: A2 targets faster app performance for supported devices.
- Speed headroom if you have the gear: U3 and the 190MB/s claim can pay off with the right DDR200 reader/device.
Tradeoffs to plan for
- Speed claims are conditional: without DDR200 compatibility, expect lower read speeds than the headline number.
- Your device matters: camera firmware and phone support can affect whether you see the benefits of A2 and high-speed classes.

Buying guide: how to choose the right microSD speed class
If you’re comparing microSD cards for video and device performance, focus on these decision points:
- Continuous 4K recording: choose a card with an appropriate video speed class (this one is V30).
- Application use on Android: check for A2 support if you plan to store and run apps.
- Transfer speed expectations: if you care about headline “MB/s” numbers, confirm reader/device compatibility (DDR200 matters for the advertised 190MB/s read speed).
- Capacity for your workflow: 128GB is usually enough for many trips, but heavy 4K recording sessions can fill it faster than expected.
Verdict
The SIX M200 128GB microSDXC card is a solid choice for buyers who need sustained recording support for 4K UHD style workflows, and who may also benefit from A2 performance on compatible Android or handheld devices. The biggest catch is the conditional nature of the “up to 190MB/s” read speed, so make sure you have a DDR200-capable reader/device if that matters to you. If you’re buying primarily for continuous recording, the V30-first design aligns well with the most consistent buyer feedback.
FAQs
Does the SIX M200 reach 190MB/s in a regular card reader?
Not reliably. To reach the advertised up to 190MB/s read speeds, you typically need a DDR200 high-speed card reader or a DDR200-compatible device. With standard readers, your speeds may be closer to what the hardware can support.
Is this microSD card good for 4K video recording?
It’s built for continuous high-bitrate video use with a V30 video speed class (minimum 30MB/s sustained write speed). That makes it a better match than basic cards for action cameras, drones, and similar continuous recording scenarios.
What does A2 mean for phone or handheld gaming performance?
A2 is meant to improve app-related performance on compatible devices, such as faster app loading and smoother multitasking. Your actual improvement depends on device support and how your apps are configured on the card.
Will it work with my dash cam, drone, or action camera?
It should work with devices that accept microSDXC cards. Just confirm your device supports microSDXC and be mindful that real-world speed depends on the device’s microSD implementation.
Is the included adapter useful?
Yes, the card includes an adapter so you can use the microSD card in full-size SD slots (for computers, laptops, or SD-capable readers that use SD cards).
