Today we will run some benchmarks with Toshiba's 32GB EXCERIA PRO SD memory card (XPRO32UHS2(BL8), which is designed for users of high-end digital cameras. The EXCERIA PRO (32GB and 16GB) cards compliant with UHS-II promise to offer impressive, near-SSD data write speeds of 240MB/sec and read speeds of 240MB/sec.
The cards are the first in the EXCERIA line-up to integrate a newly developed controller compliant with UHS-II the ultra high-speed serial bus interface defined in SD Memory Card Standard Ver. 4.10, and they achieve significantly higher data transfer speeds than earlier UHS-I compliant cards. UHS-II is the ultra high-speed serial bus interface in SD Memory Card Standard Ver4.XX that delivers data at 156MB/s by single lane access and 312MB/s by dual lane access.
Toshiba is also offering the EXCERIA series that will write at 120MB/sec.
