Reason for selling: My motherboard only supports one M.2 slot, so if I install it, I have to remove the old one. I swear to God, I bought it for 270 from Amazon, excluding shipping costs. The invoice and receipt are available for anyone who wants them, and it hasn't been opened yet. I'm selling it for 240, and I'll consider anyone who wants to buy it. Specifications: 1TB M.2 SSD, read speed 5000MB/s
