The best memory cards for DVRs

The SanDisk High Endurance memory card is designed specifically for video surveillance systems (DVRs, video cameras, action cameras) and does a good job of recording data streams in 4K and Full HD resolution. It is capable of processing a large amount of information, as evidenced by high read speeds (100 MB/s, UHS-I class) and write speeds (40 MB/s, U3 class). The flash drive belongs to the V30 video recording class, which guarantees a minimum throughput of 30 MB/s. This means that any delays and frame breaks are eliminated, and the user receives high-quality video with the ability to see all the necessary details.

The memory card case has received protection for all occasions. It is characterized by shockproof and water-repellent properties, and is immune to X-ray radiation. SanDisk High Endurance microSD U3 128 GB is adapted to high and low temperatures. The memory card will ensure the safety of data in extreme sports, when driving off-road or in the event of an accident.

128 GB of memory is enough to store several hours of 4K video, and the total duration of cyclic recording reaches 10,000 hours.

The memory card allows you to record video in FHD resolution. Features are limited for professionals as there is no 4K, but more than sufficient for home use. Belonging to the UHS-I U1 class guarantees read/write speeds of 95 and 45 MB/s, respectively, so it is more than enough for home security cameras and budget car DVRs.

High-Endurance memory cards are specially designed to work under high load conditions. They have a shock- and moisture-resistant design, are resistant to mechanical damage, and therefore are reliable data banks in the event of an accident. The manufacturer guarantees cyclic recording with a total “kilometre” of 26,900 hours.

Kingston High-Endurance 128 GB can speed up the operation of any mobile gadget, such as a smartphone. Class A1 of interaction with applications is especially relevant for mobile games, when data may not be recorded in a continuous stream, but randomly.

The model in the High Endurance line is designed to work in unpredictable conditions where the risk of damage is high. The card easily copes with mechanical overloads caused by poor road conditions or accidents, and is immune to X-ray radiation, static electricity, and water ingress.

Transcend 350V has an optimal capacity of 128 GB for cyclic recording in surveillance devices - DVRs, security systems, parental controls, action cameras. It allows you to save more than two days of life and provide access to data at high speed (95 MB/s). Filming quality is limited to FHD resolution. But thanks to this, the service life of the memory increases, since the need for cyclic rewriting will be less than with 4K resolution, due to the smaller volume of the video file. Even in the most critical situation, you can easily recover data using the proprietary Transcend RecoveRx application.

The manufacturer claims to use modern 3D NAND flash memory with a guaranteed write speed of 10 MB/s (class V10). In this case, the maximum rate can reach 45 MB/s, according to CrystalDiskMark tests. If you use a high-quality DVR, there will definitely be no problems. The only thing that confuses us is the two-year warranty on the device, which, according to the manufacturer, can withstand 120,000 hours of continuous operation. It is worth noting that Transcend 350V has been successfully sold for several years, so you don’t have to think about the bad.

The SanDisk Max Endurance microSDXC league of performance cards was released with an eye toward continuous recording of video surveillance data in cyclic mode. The models delegated from it will fit 4K video recorders, high-resolution CCTV cameras, and will perform well when shooting video on top-end cameras with interchangeable lenses.

The resource of the memory card in the “without smoking breaks” mode is 120 thousand hours, which is over 13 years of non-stop video recording. Let's be honest, not every camera can withstand such a long marathon of use. The functionality of the flash drive is maintained in the temperature range from -25 ° C to +85 ° C, and its housing is also shock-resistant, waterproof and X-ray resistant.

With speed indicators for reading and writing files, the model is absolutely top notch. Data is transferred from a flash drive at a rate of up to 100 MB/s, information is written to it at a rate of up to 40 MB/s. The minimum guaranteed recording level is 30 MB/s. It is reported by the UHS-I U3 and V30 classes assigned to the drive.

Potential problems with the drive are covered by a 10-year warranty on the flash drive directly from the American manufacturer SanDisk. Memory cards from the Extreme and Extreme Pro series from the brand’s portfolio are also perfect for mobile phones and portable video equipment. They are also covered by a lifetime limited warranty.

WD QD101 microSD 128 GB is part of the Purple series, which is aimed at use in security systems - video surveillance cameras, video recorders, both professional and for home. The card has increased reliability during cyclic recording due to special controllers that distribute the load on each memory cell. In total, you can get up to 64 TB of data written per loop.

The card has an increased working resource thanks to the use of multilayer memory technology - 96 layers. In addition, the most advanced memory technology is used - 3D NAND, which is characterized by high capacity, durability and reduced power consumption. It is able to maintain data integrity in the absence of power, so it is ideal for DVRs that do not have an autonomous power system. Thanks to constant monitoring, you can control the general condition of the card and carry out its maintenance or replacement in a timely manner.

Despite belonging to the UHS-I U1 class, shooting in 4K resolution is supported, which will allow you to see all the details in the video in the event of an accident or other need. A capacity of 128 GB is enough to record everything that happens during a multi-hour trip, even if you use a DVR with additional connected cameras, for example, rear view.
