SONY CFexpress 128GB TOUGH This is a SONY CFexpress type B card. Capacity: 128GB Max Read Speed: 1700MB/s Max Write Speed: 1480MB/s Durability: TOUGH Thank you for viewing. I purchased this about 4 years ago, but I quickly upgraded to a card with a larger capacity, so the number of times data has been written to it is low. The original box is not included. Please consider this item as a used product and understand this before purchasing. Thank you.
