SSDFactory says: Please note there is 2 version of EM7565, generic one and Lenovo one, which are not interchangeable. If you are using in a Lenovo laptop, order the Lenovo one, for all other scenarios(like use with USB adapters, or use in M2M setups, etc.) , order the generic one. We have both in stock. Just leave note on the order so we can send in the correct module.
