TOP 5 memory cards for DVRs

The SanDisk High Endurance memory card is designed specifically for video surveillance systems (DVRs, camcorders, action cameras) and does a good job of recording streaming data in 4K and Full HD resolution. It is capable of processing a large amount of information, as evidenced by the high read (100 MB / s, UHS-I class) and write (40 MB / s, U3 class) speeds. The flash drive is 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 view all the necessary details.

The case of the memory card received protection for all occasions. It is anti-shock and water-repellent, and is immune to X-rays. SanDisk High Endurance microSD U3 128 GB is adapted to high and low temperatures. A memory card will ensure the safety of data in extreme sports, when driving a car 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 loop recording reaches 10,000 hours.

The WD QD101 microSD 128 GB is part of the Purple series, which is focused on security applications - CCTV cameras, video recorders, both professional and 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 in a cycle.

The card is distinguished by an increased working resource due to the use of a multilayer memory manufacturing technology - 96 layers. In addition, the most advanced technology of the memory itself 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 time.

Despite belonging to the UHS-I U1 class, shooting in 4K resolution is supported, which will allow you to see all the details on the video in the event of an accident or other need. The volume of 128 GB is enough to capture everything that happens during a many-hour trip, even if you use a DVR with additional plug-in cameras, such as rear view.

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

High-Endurance class memory cards are specially designed to work in high-load conditions. They have a shockproof and moisture-resistant design, resistant to mechanical damage, so they are reliable data banks in case of an accident. The manufacturer guarantees cyclic recording with a total "mileage" of 26,900 hours.

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

The manufacturer carefully tests the products at all stages of production, therefore, offers a 5-year warranty, and also claims a working resource of 70,000 hours, which corresponds to 8 years of continuous recording. The Endurance class assumes the technical integrity of the memory cards throughout their lifetime thanks to the shockproof and waterproof case. When immersed in water (depth up to 1 meter), working capacity is maintained for 72 hours. The long-liver is also not affected by ultraviolet and X-rays, magnetic fields. The model can be used in professional video recorders and video surveillance systems.

The company uses the latest generation of 3D NAND flash memory of its own production and has been a world leader in this field since 2003. As a result, high data transmission standards are achieved. The UHS-I U3 class provides users with 100MB/s and 40MB/s read/write speed modes, respectively, and a minimum video processing threshold of 30MB/s (V30 class). All this allows you to record video in 4K resolution using surveillance devices. The volume of 128 GB is enough to record events with a DVR during a long car trip.

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 surfaces or accidents, is immune to X-rays, 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 this increases the life of the memory, 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 restore data using Transcend's proprietary RecoveRx application.

The manufacturer declares the use of modern 3D NAND flash memory with a guaranteed write speed of 10 MB / s (class V10). At the same time, the maximum rate can reach 45 MB / s, according to CrystalDiskMark tests. When using a high-quality video recorder, there will definitely not be any problems. Confused only two-year warranty on the device, which according to the manufacturer is able to withstand 120,000 hours of continuous operation. It is worth noting that the Transcend 350V has been successfully sold for several years, so you can not think about the bad.
