I am running a DTP office where as you know daily I have to work on data and also as you are aware that we cannot keep our data on your PC because of risk of virus and formatting and loosing our data.
We can keep data in pendrive if we are having less data but what if we have more than 100GB of data.
So I have purchased a Lenovo HardDisk model F309 of 1TB capacity from a local vendor and in the box I have found 1TB external hard disk with data cable and manual.
The Lenovo Hard Disk of model F309 comes with USB 3.0 version means the speed of copying from system to HDD and HDD to system is superb.
Overall the Hard disk of model F309 is working superb without any problem.
