WD is the best in HDD segment . seagate gives you repaired product if you have any issues. wd gives you replacement. for seagate you have to go to the service center for wd you can raise a request online and it's a door step service. it takes maximum 7 days to get you a replacement. now coming to the performance. this hdd is awesome if you are using it for storage. it's quite obvious people will buy 3 tb for storage only. if you do MBR partition then it will give 2 tb space if you do GPTpartition it will give you 2.8 tb. google about gpt to mbr or mbr to gpt partition. best way to do it from you disk management. right click on the hdd convert to gpt . voila :) overall an awesome product :)
This hard disk is better than Seagate as it is very quiet, and it comes with 2 years warranty. Go for this hard disk, this is my 2nd WD Cavair Green 3 read more
