Western digital huge n success strorage device brand all over the wold, thats why I decide to buy wd passport ultre 1 tera byte hard disk drive.this is trusted brand like dell, sony.etc.
But they cost very high as compare to the WD.this the reason to buy wd .the data transfer speed is very fast due to 3.0 usb port.i store my 4k uhd movie in hdd.
Main think is that this is portable device so I can use this device outdoor and indoor also.
