Memory-vendor Kingmax today unveiled a waterproof and dustproof 64GB SDXC (Secure Digital eXtended Capacity) memory card. The new Class 10 memory card offers a combination of durability and speed along with large capacity. Apart from being waterproof and dustproof the memory card offers speeds of up to 65MB/s (read) and up to 40MB/s (write). A huge 64GB capacity makes the card perfect for storing large files. The card also uses the exFAT (extended File Allocation Table) file system, allowing the card to overcome the limitations of the FAT32 system, and store files larger than 4GB. Other features include built-in ECC (Error Correction Code) and RoHS compliance. Kingmax did not reveal information regarding the availability or pricing of the 64GB SDXC memory card.
