Transcend launches microSD cards with SLC NAND Flash

MicroSD cards can be used in a variety of situations – whether it be climbing Mount Everest or playing Nintendo Switch. Some cards are made to be fast, working in cold temperatures or to be able to store vast amounts of data. Now Transcend launches microSD cards with SLC NAND Flash that are designed to boost burst write speeds.

For those who wonder what the SLC technology brings to the table, ADATA explained it like this: “SLC enjoys faster speeds and a longer service life, but come with a higher cost. TLC, on the contrary, is slower, has a shorter service life, but costs less in comparison.” Most SSD's and almost all microSD cards utilize the TLC technology – which Transcend now is looking to change.

Transcend’s USD230I storage range from 2GB up to 64GB and is able to operate in temperatures varying from -40°C ~ 85°C. The read speed is specified to 100 MB/s and the card features write at a speed of up to 70 MB/s – with users being able to write up to 5800 terabytes before the microSD card from Transcend taps out.


Transcend makes it clear that these cards are aimed for industrial use, saying that the “cards are the ideal solution for small form factor and write-intensive applications such as medical devices, surveillance systems, and POS terminals”. The cards feature “Built-in ECC (Error Correction Code)” and S.M.A.R.T. function – both functions are made to increase the durability and reliability of the cards produced by the company.
