TEAMGROUP HIGH Endurance 256GB 3 Pack Micro SDXC UHS-I U3 V30 100MB/s Designed for Monitoring Stable Durable Long Lasting Flash Memory Card Security Camera 4K&Full HD Video Recording THUSDX256GIV3065

I have went through many sd cards to find ones that work for me. I use these with my dashcam and am constantly writing over them and formatting them. I transfer the footage to my computer and use them in videos also. They work great!

I have never bought any TeamGroup stuff but I hear good things so decided to try them out. I have been setting up security cams and these being so cheap made them perfect choice for me. What I didn't expect was how much faster than my standard Samsung card it was. These are so fast I decided to keep one for my phone and ordered another to replace it.Nice job TeamGroup, I am impressed. I did full capacity test like I always do with sdcards and all is good!I recommend these cards highly, so cheap but yet so fast!

Excellent Price and Quality

Like it.

I have been using these for several months with Reolink security cameras (4k models) and have not had any issues. They format without issue and I have not had any corrupt footage yet.

Bought for my dash cam, so far so good. Definitely holding a couple weeks worth of drives. At least 3 weeks.

Exceptional quality for the price!! Will definitely buy again. Thanks

Update: After more testing, I have discovered that the problem with these cards is that each time you start writing a file, there is chance that you may see a delay of up to 12 seconds before the card finally starts writing data. Once the data finally starts flowing, the cards are actually very fast, maintaining 80 MB/s write speeds in a typical SD card reader. Unfortunately, this is why they fail to function properly in my dashcams, as it seems that the dashcam is constantly switching back and forth between writing to 3 different files for the 3 different cameras. Every time it switches which file is being written to, there's a chance for it to encounter the up-to-12-seconds delay where ZERO data is being written, causing the dashcam to malfunction. A dashcam which is unable to record constantly is not protecting its driver if something happens during the missing gaps of time. Team Group has replied to my initial review and suggested that I initiate an RMA to get them replaced under warranty. If I do end up receiving replacements, I will add another update after thorough testing.Original review: I bought the 3-pack of 256GB High Endurance cards. These cards are sold with the V30 and U3 ratings, both of which are supposed to guarantee a continuous write speed of 30MB/s to support 4K video recording. I attempted to use these cards in 2 different dashcam models, one which records at 6.7MB/s and the other at 3.7MB/s. Unfortunately, they couldn’t handle it. They lag behind and cause the less demanding dashcam to crash/reboot, missing chunks of time ranging from 5-45 seconds long. In the more demanding 3-camera dashcam (which also runs quite hot) the cards sometimes fail to record AT ALL for hours at a time. When this brand of cards are on sale, they can be the best deal for general purpose storage, but I cannot recommend the TEAM High Endurance cards for video recording. Additionally, I have a TEAM PRO+ 256GB card, and that card can JUST keep up with the 3.7MB/s dashcam, but it chokes in the 6.7MB/s one. So I can’t recommend it either.Based on firsthand experience I can recommend:Samsung Pro PlusSamsung Pro EnduranceSanDisk ExtremePNY Premier-X

Buen producto. Funciona bien. Buen precio. Las cámaras las reconocieron de inmediato. Hasta el momento sin problemas.

والله الصدق كنت متخوف شوي من ذا الشركةالى ان قويت عنها ودريت ان عليها ضمان سنتين 👍🏼(يبين لك جودة المنتجوالسعر ولا غلطة على المواصفات اللي فيه

3 bought for security cameras, all have been working great for the last 6 months with no loss of video.

I’ve bought this is sd card last year on December. The readings now are very slow and it doesn’t work properly on my dash cam.
