The SanDisk Extreme Portable SSD with 1TB of storage supports USB Type-C connection and enables fast data transfer. Purchased for backing up a Mac PC, but insufficient capacity led to the additional purchase of a 2TB drive. Formatted for Mac use after purchase, but has never been used. (Photos show both the 1TB and 2TB drives, but the sale is for one 1TB drive) - Brand: SanDisk - Model Name: Extreme Portable SSD - Storage Capacity: 1TB - Connectivity: USB Type-C Thank you for viewing.
