These UHS bus interfaces indicate the theoretical maximum read and write speeds, unlike the sustained write speeds of speed classes. UHS-II: theoretical maximum transfer speeds up to 312MB/sīoth U1 and U3 memory cards can utilise the UHS-I bus interface, but are not compatible with the UHS-II bus interface.UHS-I: theoretical maximum transfer speeds up to 104MB/s.What makes the U1 and U3 memory cards more advanced than those in the Speed Class are that they use one of two UHS bus interfaces: As a rule of thumb, 4K-capable recording cameras will usually require at least a U3-rated SD card. The UHS Speed Class mainly refers to the minimum sustained write performance for recording videos and came about due to 4K-capable video recording devices needing faster write speeds. The UHS Speed Class is more commonly used nowadays than the Speed Class and many high-end cameras require at least a U3-rated memory card for many of its functions, such as recording high-resolution videos. U3 (UHS Speed Class 3): minimum write speed of 30MB/s.U1 (UHS Speed Class 1): minimum write speed of 10MB/s.There are two ratings within the UHS Speed Class: They are not backward compatible with standard SD Memory Cards.Į-mail: in the press releases, including product prices and specifications, content of services and contact information, is current on the date of the press announcement,but is subject to change without prior notice.The next speed class up is the UHS (Ultra-High Speed) Speed Class and it’s denoted with the “U” symbol.

SDHC Memory Cards can be used with devices that support the SD Memory Card Ver. Maximum read and write speed depends on such factors as device and file size.

Toshiba will continue to expanding and upgrade its SDHC and SD Memory Card series to meet the growing demand for high speed, high capacity products. Toshiba rounds out its latest additions with a 2GB microSD Card, reinforcing its overall product line-up in all key areas. This advance will bring new levels of performance and functionality to mobile phones and other personal digital products. With the new 4GB miniSDHC Card, Toshiba brings to market the industry's first Class 4 miniSDHC Card, capable of sustained write speeds of 4MB/s. The new 4GB SDHC Card extends the Company's line up of 4GB SDHC beyond the Class 4 card launched in September. Toshiba's new 4GB Class 6 SDHC meets the ultra high speed Class 6 rating, and delivers a guaranteed sustained write speed of 6MB/s Toshiba has measured sustained performance at a maximum of 20MB/s. Demand for miniSDHC Cards and microSD Cards will primarily come from mobile phones. The market for these high performance memory cards will grow alongside increasing demand for digital equipment able to handle motion pictures and high resolution images without long delay times. The SD High Capacity standard (version 2.00) takes card-based memory into the broadband era by defining three classes of high speed data write for cards with an enhanced capacity of 4GB and more. The new SDHC and miniSDHC Cards will be available worldwide from March next year, and the microSD will be launched worldwide next April. TOKYO-Toshiba Corp., a leading innovator in memory card solutions, today announced the latest enhancement to its extensive line-up of SD Memory Cards: a 4-gigabyte (GB) Class 6 SDHC Card a 4GB Class 4 miniSDHC Card and a 2GB microSD Card. Toshiba Adds New High Performance SDHC Cards and High Capacity microSD Card to Extensive Memory Card Line-up
