Transcend has introduced new MicroSDXC cards with SLC caching for increased burst write speeds. The new USD230I memory card from Transcend has been equipped with 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.
“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, 70 TB for the 16 GB and 32 GB variants, and 140 TB for the 64 GB variant.” explains the Tech Power Up website.
Enhanced Performance with SLC Caching
The introduction of SLC caching in the USD230I memory card is a significant advancement in the realm of MicroSDXC cards. SLC (Single-Level Cell) caching allows a portion of the NAND flash memory to operate in SLC mode, which is known for its superior write speeds and durability compared to MLC (Multi-Level Cell) or TLC (Triple-Level Cell) NAND. This technology is particularly beneficial for applications that require quick bursts of data writing, such as high-resolution video recording, burst photography, and other data-intensive tasks.
For instance, photographers and videographers who often work in challenging environments will find the broad operational temperature range of -40 to 85 °C particularly useful. This ensures that the card can perform reliably in extreme conditions, whether it’s the scorching heat of a desert or the freezing cold of a polar expedition.
Capacities and Endurance
The USD230I card is available in multiple capacities to cater to different storage needs. The 8 GB variant offers an endurance of 36 TBW (Terabytes Written), making it suitable for users who need a reliable storage solution for moderate data writing tasks. The 16 GB and 32 GB variants, both offering 70 TBW, provide a balanced option for users who require more storage and higher endurance. The 64 GB variant, with an impressive 140 TBW, is ideal for heavy users who need extensive storage and high endurance for continuous data writing.
The endurance ratings of these cards are particularly noteworthy. Endurance, measured in TBW, indicates the total amount of data that can be written to the card over its lifespan. Higher endurance means the card can handle more data writing before it starts to wear out, making these cards a reliable choice for long-term use.
Applications and Use Cases
The USD230I MicroSDXC cards are versatile and can be used in a variety of applications. In addition to photography and videography, these cards are suitable for use in industrial applications, where reliable and durable storage is crucial. For example, they can be used in surveillance systems, automotive data logging, and other industrial equipment that operates in harsh environments.
Moreover, the high sequential transfer rates of up to 100 MB/s and random access speeds of up to 3,400 IOPS make these cards suitable for use in smartphones, tablets, and other portable devices that require fast and efficient data access. This ensures smooth performance and quick access to stored data, enhancing the overall user experience.
