Transcend Intros MicroSDXC Card with SLC Caching for Increased Burst Write Speeds

Transcend introduced the first microSDXC memory card to feature SLC caching technology. The new USD230I memory card from Transcend features a host-transparent internal logic that treats a small portion of the 3D TLC NAND flash as SLC, to improve write performance in short bursts. This should particularly help in usecases such as high-quality burst photography or high-resolution video recording. The card is also endowed with a broad operational temperature range of -40 to 85 °C. The USD230I offers sequential transfer-rates of up to 100 MB/s, with up to 3,400 IOPS random access. It comes in capacities of 8 GB, 16 GB, 32 GB, and 64 GB, offering endurance (TBW) of 36 TB for the 8 GB variant, 140 TB for the 16 GB and 32 GB variants, and 58 TB for the 64 GB variant. The company didn’t reveal pricing.
