Samsung T9 1TB Portable External SSD in excellent working condition.
There are no issues with this drive and it's been stored in a weather sealed case with silica packs.
Due the fact that it is an SSD, I cannot guarantee the lifespan on any drives. All I can provide is the diagnostic report (pictured above) that I ran with Samsung's official software prior to packaging. Therefore, since it's priced to sell and listed as used, all sales are final.
