Up to 100MB/s read speed, up to 40MB/s write speed. Based on internal testing; performance may be lower depending on host device, usage conditions and other factors. 1MB=1,000,000 bytes. Les vitesse de lecture sont toujours plus rapides que l'écriture, on ne les annonce pas sur les spécifications, mais ici, il est précisé 100Mo/s, donc 3 fois plus rapide que l'écriture Designed for high endurance and durability so you can record for up to 20,000 hours with no worries You can have a Samsung Pro Endurance card that fails within a month or an older Sandisk Ultra card that lasts years without having a problem. Still, over thousands of cards, the Ultra cards will fail way earlier than the Pro Endurance models. We make our recommendations based on hundreds of reports, not a couple people saying it works or has problems. The Competition Sandisk Max Endurance With capacities of up to 256GB, you can record and save more footage between rewrites Handles Harsh Conditions.

SanDisk High Endurance 128GB microSDXC card with Adapter - Very

Bought to replace the factory 32GB Sandisk memory card used in the car camera 'BMW Advanced Car Eye' (original 2015 ACE model, not the newer ACE 2.0 or ACE 3.0 models), which I believe was also a max endurance unit. The 32GB keeps filling up too fast and the camera OS would constantly repeat the card needs defragmentation. Like inside of a month. This is unworkable. Its a minefield trying to find out what format BMW ACE wanted these cards in. After much trials it needs to be formatted with MBR FAT32. Not GPT. Newer versions of Windows 10, 11, macOS 10.12 thereabouts onwards have started removing the option to format the larger capacity cards as FAT32. So you have to do it via command line. I did it in macOS Yosemite's Terminal. Only after I managed to format this 128GB as FAT32 with partition map scheme = MBR did ACE accept it and resume recording. Used Terminal commands below, provided as a reference, you must do your own homework before executing it: Comes in A1 or A2 rated SD cards.

One of the most important but least known characteristics of microSD cards is the NAND type. The NAND type describes how the physical cells that store information were constructed. SD vs microSD There are two physical sizes, SD and microSD. In 2019, all consumer dash cams we’ve seen use the smaller SD card size. There are only a few specialized cameras we’ve seen that use the larger SD card size. As well nearly all microSD cards include an SD card adapter so you’re covered for all uses. 3D NAND Reigns Supreme Consumers used to see only two types of flash memory: TLC (Triple Level Cell) and MLC (Multi Level Cell). Both are planar (flat) which means all memory cells are on one layer. Error-correction, wear-leveling and other write-heavy optimizations prevent the corruption of your videos files and improves lifespan. Most consumer cards focus on speed as they are used in smartphones and other devices that aren’t continually writing data. We see more issues with corrupted videos on budget cards, significantly fewer reports on Endurance models. Read this white paper (PDF) by Sandisk to learn more. Rated for Years of Recording Time

In 2018 numerous 3D NAND factories became operational which has caused a glut in supply and dropping prices. As well a new major Chinese manufacturer – Yangtze Memory– may lead to a 3-year oversupply period. For dash cam owners, this is a great time to update an older memory card. Unexpected Oversupply in 2020 Built to last, this microSDXC card can reliably capture video day after day so you can rest assured that you’ve got your eye on what matters most. High endurance lets you record and re-record It is this second card I have used from 10 November 2020 until 28 July 2021 when today the A139 today told me Storage Error No Sd Card Found.Actual hours of video saved less. Up to 40,000 hours for 512GB; 20,000 hours for 256GB; 10,000 hours for 128GB; 5,000 hours for 64GB; and 2,500 hours for 32GB. Full HD video only; total hours less for 4K UHD video.

UHS Speed Class 3 (U3) and UHS Speed Class 1 (U1) designate performance options designed to support real-time video recording with UHS-enabled host devices. Video Speed Class 30 (V30), sustained video capture rate of 30MB/s, designates a performance option designed to support real-time video recording with UHS-enabled host devices. See www.sdcard.org/consumers/speed. A very promising new card with the best warranty and endurance rating of any consumer card I’ve seen. Their 128GB and 256GB cards have a 10 and 15 warranty. My thoughts – not worth the money. Il s'agit ici du standard U3 qui est le plus courant actuellement et qui permet d'écrire de la vidéo en 4K même en étant pas trop compressé. Cela est aussi parfait pour votre téléphone pour y ajouter de la mémoire sans attendre pour voir les images s'afficher.While it would be great if all our readers selected an endurance microSD card, larger 128GB+ endurance cards are significantly more expensive. We had to find a budget option with good reliability. Here’s how we made our recommendations: Doing Endurance Testing on MicroSD Cards Is Difficult Professional drivers may want to use the larger 128GB+ cards to answer any complaints about their driving. These cards are more expensive per gigabyte and aren’t worth it for the average driver. Why Endurance Cards Are Our Top Choice Price changes will affect whether a card is worth buying especially in certain markets with limited availability for our recommended cards. As well our recommendations aren’t equal, a proven card with a warranty like the Samsung Pro Endurance is worth paying more money compared to the less proven Transcend or Kingston microSD cards. Step 1: Eliminate Overpriced Cards Several years ago prices were nearly double as manufacturers switched to building 3D NAND factories causing a shortage of memory driving up prices. Generally, there’s a 2-year shortage followed by a 2-year oversupply period. Oversupply in 2018 & 2019 Built to last, this microSD card can reliably capture video day after day so you can rest assured that you’ve got your eye on what matters most.
