I need always dealing with Huge Data. I have two External HDD, one is from Sony with 1TB and one is Seagate HDD with 1.5 TB. I have bought Seagate HDD because I was not happy with Sony HDD, because it was giving slow speed as well 1TB was not enough for me.
Pros:-
Seagate is well known company for making internal and external HDD and we can buy it with confidence. I have used many HDD in past of Seagate and almost never faced any issue with it.
1) This HDD is with USB 2.0 compatible and can give good speed of data transfer.
2) Reasonable price and well branded product, so not need to worry about quality.
3) This HDD come with Seagate Backup software and it can help us if we accidentally loss data.
4) Most of HDD not giving space as they mention in description but this HDD have full 1.5TB storage.
Cons:-
1) Some time this HDD is going more hot than in normal condition.
2) HDD giving some more noise than other HDD.
3) This HDD have not USB 3.0 compatibility, it must as new technology.
Final Words:-
I am using this HDD from last six month and have not faced any major issue, as well speed is still same as new. I recommending this HDD if you are getting in reasonable price.
