MindStor Micro SDXC 128GB Memory Card with 90MB/s read speed
Quick take
This MindStor 128GB microSDXC card is aimed at continuous loop recording, making it a practical pick for dash cams and 24/7 security cameras that write data all day. It includes an SD adapter, targets Full HD (1080p) recording, and supports A1 app performance use in phones and tablets. The main buying caveat is that formatted capacity will be lower than 128GB, so plan storage around real-world usable space.
Pros and cons
Pros
- Designed for loop recording in dash cams and security cameras (1080p support).
- Claimed fast access with up to 90MB/s read speed, plus U1/A1 performance class for general device use.
- Comes with an SD adapter for easier transfers and compatibility with SD card readers.
- Durability-focused build claims (temperature, shock, water, and X-ray resistance).
Cons
- Formatted capacity is expected to be less than the advertised 128GB (buyers report around the mid-110GB range after formatting).
- Review evidence is mostly “works fine so far,” so long-term endurance is still an open question for constant high-write use.
- Speed is stated as a maximum read figure, so real write speeds in your device may differ.
What buyers think
Buyer-review evidence for this card is limited in detail, but the recurring themes are encouraging. Multiple buyers mention straightforward installation and formatting, and they report that it works as expected for dash cam or ongoing recording. Playback quality for HD video is described as solid, and some users specifically call out no errors, no corrupted files, and reliable transfers during early ownership. There is also consistent agreement that usable storage after formatting is lower than the advertised capacity.
What this card is for
This is a microSDXC card positioned for devices that continuously write video data. That includes dash cams and home or business security cameras that use either continuous loop recording or motion-triggered recording that repeatedly overwrites older clips. If your recorder supports microSDXC and targets Full HD (1080p) recording, this card’s feature set is built around that workload.
Performance and speed, in practical terms
The card’s headline spec is a claimed read speed up to 90MB/s. In everyday use, that translates to faster access when you pull footage for review or download clips to a phone, tablet, or computer. It also supports SD performance classes U1 and A1, which are typically relevant for smoother app performance (random access IOPS) on compatible Android devices.
For dash cams and security cameras, the key question is consistency during continuous writing. The product positioning emphasizes no frame drops and uninterrupted 1080p recording. Still, actual results depend on your camera’s formatting, bitrate settings, and whether it’s tuned for the card type and speed class.
Capacity and what “128GB” really means
The advertised capacity is 128GB, and the available storage after formatting will be lower. That is normal for microSD cards, but it matters because dash cams and security cameras overwrite old footage. If you rely on several days of history, choose your card size based on both your camera’s bitrate and the usable formatted capacity, not just the marketing number.
Durability and everyday resilience
The card is marketed as resistant to temperature, shock, water, and X-rays. While those claims are intended for harsh environments like cars and outdoor installations, your best protection still comes from installing the card correctly and using it within your device’s supported operating conditions.
Setup experience and compatibility
Buyers report that setup is quick: insert the card, format it in the device, and recording begins within minutes. The included SD adapter is helpful for transferring files through a computer or an SD card reader, rather than relying only on a device’s cable.
Compatibility will depend on whether your device supports microSDXC cards at this capacity. If your camera or recorder has specific requirements for speed class or maximum supported capacity, check those first.
Pros and cons for different buyers
Best for
- Dash cam owners looking for a 128GB microSDXC option aimed at loop recording.
- Home or small business security cameras that record at Full HD (1080p) and need continuous storage.
- Android users who want the card to do more than just video recording, with U1/A1 app performance positioning.
Who should be cautious
- Buyers who need exact storage planning, because formatted usable capacity will be lower than 128GB.
- People expecting guaranteed long-term endurance based on early ownership only, since review evidence is mostly early-stage stability.
- Anyone using high-bitrate or higher-than-1080p workflows should confirm their device’s requirements before buying.
Price and availability
This model is listed as a single 1-pack microSDXC card and is currently shown as in stock for the US market. If you are price-sensitive, compare total cost per usable gigabyte after formatting, not just the sticker price.
Verdict
The MindStor 128GB microSDXC card is a solid value-oriented pick for dash cams and 1080p security recording, especially if you want an SD adapter included and you prefer a card that buyers report installs cleanly and records without early issues. Just remember to account for reduced formatted capacity and confirm your device is compatible with microSDXC and your recording settings.
FAQ
Is this MindStor microSDXC card good for a dash cam?
It is designed for dash cams and security cameras that use loop recording, with positioning for Full HD (1080p) capture. As with any dash cam card, make sure your specific dash cam supports microSDXC and that you format the card in the camera for best compatibility.
Will I get the full 128GB usable storage?
No, formatted capacity is typically lower than the advertised number. Buyers report ending up with roughly the mid-110GB range after formatting, which is normal for microSD cards.
What does U1 and A1 mean for this card?
U1 is generally about minimum sequential performance for app and device use, while A1 is associated with optimized random IOPS for smoother app performance on compatible phones and tablets. For dash cam recording, the main factor is whether the card performs reliably under continuous writes in your camera.
Does it include an SD adapter?
Yes, the package includes an SD adapter, which can make it easier to use the card with an SD card reader or transfer files without depending only on your camera or phone.
How reliable is it for long-term constant recording?
Early user feedback is positive, with reports of stable recording and no errors during early ownership. However, review evidence is limited in time, so long-term endurance under heavy, continuous use is still something you should consider based on your camera’s requirements and your own usage intensity.
