Used with the SONY α7RV. This is a genuine CFexpress Type A memory card. Purchased around June 2023. I have multiple items listed, and they are managed by serial number. If you are buying multiple items, I will consider a discount, so please let me know! I've used it for about two years, but I own about 6 CFexpress cards and have been using them in rotation. It's faster to write and read than SD cards, so the speed is especially impressive when handling large files. I also have a 320GB card for sale, so please consider purchasing it as well. It looks like there are scratches, but it's just the reflection of the light. - Brand: SONY - Model: CFexpress Type A - Capacity: 160GB - Read Speed: 800MB/s - Write Speed: 700MB/s - Durability: TOUGH 160GB CFexpress Type A memory card, read speed 800MB/s, write speed 700MB/s Please let me know if you have any questions.
