As we all know Apple is a brand which delivers best quality products from other brands.
Personally I like this external hard disk performance wise.
3 TB memory is far far enough memory to store datas according to me.
It got its usb port in order to transfer datas. According to me the data transfer is too fast in MB which is not compared from other pen drives and other hard disks.
Apple hard disk does not get heated soon when compared to other hard disks.
Good black sleek design . which I like the most about this external hard disk.
Coming to disadvantage part which personally do not like is its price. As we always know Apple brand charges heavy sky touching price. And other flaws part is it is too heavy and its about 1.5 kg which makes it difficult for a portable object to carry with you always. Coming to warranty part yes it is a big disadvantage as it gives only 6 months manufacturing warranty. Services in other hand is good.
I will only recommend you to use this if only you are performance oriented like me. Go for it I will recommend.
