Best 32GB Memory Card for G1WHT Video Recorder: Fast & Durable Options (Samsung 32 EVO+)

Best answers

Which 32GB microSD card should I buy for a G1WHT dashcam so it is fast enough and can handle repeated overwrites?

The better choice for the G1WHT recorder is the faster SanDisk microSDHC 32GB UHS-I/A1 card, not the Samsung EVO+; the Samsung card’s 7.06 MB/s write speed was judged too slow and effectively unsuitable [#17411646][#17411709] A class 10 card with at least 10 MB/s write speed was given as the minimum baseline, but one reply said there is no hard rule for long-term overwrite durability [#17411340] The recommended SanDisk card was measured at about 82 MB/s read and 56 MB/s write and was reported to work perfectly in a 4K sports camera [#17411680]

    Hello. I wonder what 32GB memory card to buy for the G1WHT video recorder - to be fast enough and resistant to multiple overwrites. I pre-selected such (the first on the SAMSUNG 32 EVO + list just started to fail after two years):

    The minimum of "class 10" or min. 10Mb / s record, and as for durability, I guess there's no rule, I'm ADATA after 2 years, maybe some professional camera cards? but are there any microSDs?

    You still have the guarantee for her? Do you want to change to another?

    The receipt probably disappeared somewhere. I would like to change to something stronger.

    H2testw showed for SAMSUNGA 32 EVO + the following results:
    Test finished without errors.
    You can now delete the test files * .h2w or verify them again.
    Writing speed: 7.06 MByte / s
    Reading speed: 18.4 MByte / s
    H2testw v1.4

    The card is efficient, but the speed is probably not too (?)

    Tamta is better at sports cameras. Reading 82Mb / s, writing 56Mb / s. Measured by the application. Mounted in a 4K camera with 3D recording, it works perfectly!

    So in summary, which will be a better purchase - they are at the same price:
    Number one
    Number two

    And as with the SAMSUNGA parameters - is it still suitable for something or a basket?

    It's okay 2. And what about Samsung is probably a basket. With such speeds.

    My little worries about video recorders got a lot and I came across an extremely important issue in the memory card in the video recorder.
    This is a matter of MLC vs. TLC memory type. Grab the article:

    I am currently in the process of choosing the right camera and art explained a lot about the cards

FAQ

TL;DR: G1WHT owners: avoid slow cards; 7.06 MB/s write is weak—"The card is efficient, but the speed is probably not too (?)". Use this FAQ to pick a fast, durable 32GB option. [Elektroda, -Obywatel-, post #17411646]

Why it matters: Dashcams overwrite nonstop; slow or low-endurance cards risk lost clips when you need evidence most.

Quick Facts

What’s the best 32GB microSD card for a G1WHT dashcam on a budget?

From this thread, choose the SanDisk Extreme microSDHC 32GB A1 (SDSQXAF-032G-GN6). It was confirmed as the better pick versus the alternate listing at the same price point. The A1 variant was explicitly endorsed as “OK” and selected. [Elektroda, Pedros050, post #17411709]

Do I need Class 10 or U1 for reliable dashcam recording?

Yes. “The minimum of ‘class 10’ or min. 10Mb/s record.” That baseline aligns with continuous video capture needs in 1080p recorders. It reduces the chance of dropped frames during loop recording. [Elektroda, procsa, post #17411340]

My Samsung EVO+ 32GB writes at 7.06 MB/s in H2testw. Is it still usable?

That’s too slow for dependable dashcam use. The H2testw report showed 7.06 MB/s write and 18.4 MB/s read, and it “finished without errors.” Passing verification does not fix inadequate speed. Replace it for recording reliability. [Elektroda, -Obywatel-, post #17411646]

SanDisk Extreme 32GB: standard vs A1—which should I buy?

Pick the A1 version (the second listing). It was specifically confirmed as the right choice in the thread. If both are the same price, take the A1-labelled SDSQXAF-032G-GN6. [Elektroda, Pedros050, post #17411709]

Are action/sports camera cards overkill for a 1080p G1WHT?

They exceed what 1080p needs but work great. One user measured 82 Mb/s read and 56 Mb/s write and said it “works perfectly” in a 4K camera. Such speeds are more than enough for a 1080p recorder and speed up file transfers. [Elektroda, Pedros050, post #17411680]

Is SanDisk Ultra microSDHC 32GB U1 A1 a good budget choice?

Yes. It was recommended as an available, suitable option. The U1/A1 label indicates entry-level performance that matches general recording needs for 1080p dashcams. [Elektroda, Pedros050, post #17411469]

I lost my receipt—can I still use the warranty for a failing card?

First, check whether you still have a valid guarantee. If not, plan to switch to another card. That was the pragmatic advice given when a similar case was discussed. [Elektroda, Pedros050, post #17411418]

How do I test a microSD card before trusting it in my dashcam?

Use H2testw to write and verify the full card, then check speeds.
  1. Run H2testw and fill the card with test data.
  2. Confirm the report and note write/read speeds.
  3. If speeds look low for dashcam use, replace the card and re‑test. [Elektroda, -Obywatel-, post #17411646]

Does memory type (MLC vs TLC) really matter for dashcams?

Yes. Members flagged memory type as vital for endurance in continuous overwriting. As one post put it, MLC vs TLC is an “extremely important issue” for recorders. Prefer endurance‑focused cards when possible. [Elektroda, induss, post #17433526]

Can I use a 64GB card instead of 32GB?

Users also consider 64GB models (e.g., Goodram M3AA 64GB, SanDisk Extreme 64GB). Choose 64GB only if your recorder supports microSDXC. Verify compatibility in your device manual before buying. [Elektroda, Bitels85, post #17508457]

When should I retire a dashcam card?

Retire it when speeds degrade or the recorder shows instability. Regarding a slow Samsung EVO+, one member said it’s “probably a basket” with such speeds. Treat underperforming cards as unreliable for evidence capture. [Elektroda, Pedros050, post #17411709]

Where can I read more tests and buyer guides for microSD cards?

A member shared links to comprehensive roundups and dashcam‑focused guides. Use them to compare performance tiers and endurance claims before buying. They help shortlist dependable models. [Elektroda, Bitels85, post #17508457]
