Kenwood KNA-SD16C/32C

Kenwood will release microSDHC memory cards "KNA-SD16C (16GB)" and "KNA-SD32C (32GB)" that use the 3D NAND pSLC method, which is highly durable and excellent for long-term storage, from late January. Release. Drive recorders are becoming more and more popular as a way to prepare for trouble while driving.However, the SD card that records driving video needs to be rewritten frequently, so internal parts deteriorate quickly and errors occur. easier to do. The new product adopts the 3D NAND type pSLC method, which is mainly used for commercial products, in order to prevent recording errors caused by defective SD cards. Compared to the conventional 2D NAND type, which increases cells in a plane, the effect between adjacent cells is reduced. It also has high reliability, such as excellent durability against repeated writing and resistance to fragmentation. The number of rewrites and data retention period is about 100 times that of the general 2D NAND type TLC method, and about 10 times that of the highly durable 2D NAND type MLC method and 3D NAND type TLC method. In addition, by using it with the company's drive recorder that can be linked with new products, it is compatible with the "SD card life notification function" that informs the replacement time of the SD card by screen display and voice. Prevent recording errors due to the life of the SD card. The estimated market price is around 5500 yen for KNA-SD16C and around 8800 yen for KNA-SD32C.
