The 64GB SDXC Memory Card Gold Series Class 10 UHS-1 from Panasonic features a maximum read speed of 90MB/s and a maximum write speed of 45MB/s, with minimum transfer rates of 10MB/s. This Class 10 UHS-I card is a member of Panasonic's Proof 7 collection, meaning it can withstand water, shock, magnetic fields, X-rays, extreme temperatures and electrostatic forces, and also contains a safety fuse to protect against overheating.
The card has Smart Guard Protection, which safeguards against errors, power failure, and write damage. The Intelligent Controller automatically refreshes data before the errors become too numerous to be corrected. The controller also retrieves data that has been damaged due to power interruptions. Smart data writing technology equalizes rewrite frequency on each writing block, reducing the risk of damage caused by repeated rewriting to the same areas. The card's Multi-Level Cell (MLC) flash memory is long-lasting, allowing data to be rewritten up to 10 times as often as Triple-Level Cell (TLC) memory allows.
