This lenova hard disc does not provide good performance.I really disappointed after using this product l.I used this hard disk for last 2 months and I faced some issues while trying to store my important documents.Even data in this hard disc doesn’t perform well.The speed of transferring data is very slow.It takes long time to read and write a data.I found a hitting issue while using tjis external hard disc to store larger files.I complained this issue to lenova customer service.but I didn’t receive any solution from customer service. The hard disk is only waste of money and the service is very low and poor.
