External harddisks are to extend the storage when our laptop storage is not sufficient.In my laptop has of just 320Gb.It is not sufficient for me.Hence I bought this Seagate 4Tb external harddisk.It was easy to carry and stores large amount of data.The main advantage with it is large storage.But it was very delicate.It become a drawback for us.We must take care about it.Else we have to lost our data as well as money.But my laptop having 3 USB ports.But in which only one is working.Remaining two are not working.When I connected my Seagate harddisk to.laptop, I feel bad.
Because if I want to connect any pendrive, I must have to remove this harddisk and connecting again by me.Then it is loading high loading time to showing its internal data.
