You need to be extremely careful when picking memory cards for driving recorders. Especially pay attention to these three points: strong storage particles, large enough capacity, and fast reading and writing speed.
Many people wonder whether they should focus on speed or capacity when choosing memory card. Nowadays, most cards have big enough capacity, you should focus more on speed and other aspect when purchasing cards
MLC and SLC are two main structure of NAND flash memory. Before, SLC was widely used by many manufacturers, but afterwards, manufacturers start to develop MLC-based flash cards. MLC has higher storage density and more potential.
With the development of technology, the need for micro SD card on phones has dropped, but its use in other devices has increased. You can choose the most suitable SD card base on your need.
Although uSD is very small, its structure is very compact, with own controller, memory, and NAND Flash and an FTL layer to achieve load balancing. It includes all elements of Von Neuman and is almost identical to TF cards.
SLC products are now used in industrial field due to its reliability and toughness. ADATA, TDK, INNODISK and TOPSSD has all released their new products based on SLC.
Yangtze Memory has successfully launched its 128-layer TLC/QLC flash memory chip. It becomes more compatible in the global market and will play an important part in balancing global supply.
With more investment in 5G network and data center construction, the need for storage has risen sharply, enterprise level NVMe SSD will be shipped in the second quarter.
SD Association had many innovations since it was founded 20 years ago by three leading enterprises in memory card field. It has done an excellent job in promoting SD standards and encouraging the innovation of SD card technology.
There are many memory cards in the market. When purchase, it is recommended to buy cards as quickly and large as possible. UHS II and V90 will become the mainstream in the future.
