This 120GB XQD memory card boasts a read speed of 440MB/s and a write speed of 400MB/s. I'm selling it because I'm changing equipment. I was using it until recently. It works without any problems. The white area on the back is where I peeled off a sticker. It works without any problems. This is the lowest price, no discounts. - Brand: SONY - Model: XQD - Capacity: 120GB - Read Speed: 440MB/s - Write Speed: 400MB/s - Country of Manufacture: Japan Thank you for looking.
