Maximum capacity 2TB, ultra-fast data transfer with a maximum read speed of 1050MB/s. Supports USB 3.2 Gen 2 for ultra-fast transfer speeds. The exact period of use is unknown. I mainly used other SSDs, so I haven't used this one much, and its usage frequency is low. However, please understand that this is a used item before purchasing. The box may show signs of use or deterioration from storage. ⚠️I'm very sorry, but I'm not in a hurry to sell, so I'm not considering a discount.
