I have been using Seagate portable hard drive from past 6 months and I had not face any of the technical problems from this.
Storage wise 1.5 tb is enough for a normal person.and there is no problems like erase of memory or anything.
As it is a portable hard drive, its built quality is attractive as well as strongly built.
There is no temperature ups or downs problem for inner bus damage as it has a outer thick metal.
It had been a great storage support for my pc and I would prefer you to buy this product.
