Two SUNEAST CFexpress Type B 128GB cards. First come, first served! Ultra-high performance SSDs. I took photos just now, but I'm selling them because I changed models and hardly used them. As shown in the photos, they have fast write and read speeds without any issues. The transfer speed is limited by the CFexpress card reader and the PC's Type-C connection, so the actual speed should be even faster according to the manufacturer. Please take this opportunity to use them as spare memory for your camera. Serial numbers are managed at the time of sale, and any malicious product swapping will be reported to the Mercari business department and the police. I look forward to a pleasant transaction.
