      Size Name: 256 GBStyle Name: High EnduranceVerified Purchase
      I bought this SanDisk High Endurance microSD card specifically for my dashcam, and it's been performing flawlessly.
      The 256GB capacity is excellent, allowing for plenty of recording time before the card starts overwriting. I highly recommend this card. It's a bit pricier than standard cards, but the reliability and longevity are well worth the investment. I've had no issues, and I feel confident that my recordings are safe. I would recommend this to anybody who needs a reliable SD card for constant recording.

      5.0 out of 5 stars worked as expected using MicroSD speed test utility
      Reviewed in the United States on 26 February 2025
      Size Name: 256 GBStyle Name: High EnduranceVerified Purchase
      I grabbed the SanDisk 256GB High Endurance microSDXC a couple months back for my dash cam, and honestly, it’s been pretty great so far. The storage is unreal—256 gigs means I can record forever without stressing about it looping over stuff I might need later. They say it’s good for like 20,000 hours, which sounds insane, but I guess that’s why it’s made for constant recording. My car turns into an oven in the summer, and this thing just keeps chugging along, no complaints. Plus, that little adapter it comes with? Super handy for pulling footage onto my laptop without fumbling around.

      It’s been smooth sailing with 4K video on my dash cam—no weird skips or anything, which was my big worry. Popped it in, formatted it quick, and it was ready to roll. The read speed’s decent too—around 100MB/s—so I’m not sitting there twiddling my thumbs waiting for files to move. SanDisk’s always been my go-to, and this feels worth the cash compared to some other cards I was eyeballing.

      A micro SD card designed specifically for devices that demands high read and write cycles that prioritize reliability such as dashcams in extreme temperatures and home security systems. It'll be useless to have an expensive device without a reliable SD card that can match its performance to deliver you a guarantee of important data being securely saved.
      Performance: Besides the ability to last way longer than standard SD cards, the read and write speeds on this card is boosted to meet the intense workload put onto it by recording devices. This card can quickly and efficiently write down hours and hours of uninterrupted footage with little chance of corruption.
      Durability: The high built quality of the card ensures longevity of its lifespan, keeping it reliably operational for way longer than other micro SD cards that might not even be used as often as this one. Loop video recording are very strenuous on memory cards and this one is able to take it on with no problem.

      Such high performance standards are often unnecessary for the average person, but for anyone running dashcams or home security systems that cannot afford to have data corruption, I highly recommend paying the extra money to get this reliable card as it can be a life savor. Again, it's pointless to have an expensive system just to have it fail due to the external micro SD card not being able to keep up. This card should be pocket change compared to those systems, and will ensure that every penny of your money spent on your security systems is being put to use.

      I recently got the SanDisk 256GB MAX Endurance microSDXC Card with Adapter for my dash cam, and it's been fantastic. With its huge 256GB capacity, I can store hours upon hours of high-definition footage without constantly needing to clear space.

      One of the best things about this card is its durability. It’s designed to handle up to 120,000 hours of recording, which translates to around 13 years of continuous use! I feel confident knowing that my data is secure and the card won’t wear out quickly, even with heavy use in my dash cam.

      The speed is also impressive. The card supports smooth 4K UHD video recording and playback, with read speeds of up to 100MB/s and write speeds up to 40MB/s. This means I get seamless high-resolution video without any annoying lag or buffering.

      Plus, it’s built to withstand tough conditions. My dash cam often faces extreme temperatures, but this card is temperature-proof, waterproof, shockproof, and X-ray-proof. It performs reliably no matter what.

      The included SD adapter is a nice bonus, making it easy to transfer files to my computer. Overall, the SanDisk 256GB MAX Endurance microSDXC Card has been a great investment for my dash cam. Its capacity, speed, and durability have exceeded my expectations, and I highly recommend it.
