Seagate plus slim 1 tb or 2 tb you can consider any one ??
Some facts that tells thsi is the best
Dell , hp , acer all contracts seagate for harddisk and memory storage to install in their laptops
So if they believe in this why u cant ??
Dell also sells their external harddisk under the name dell but they are originall manufactured by seagate u can sell drivers inside the harddisk.
Just one brand in the line which can compete with this WD ( its on top)
