I am using the external drive as my data backup without any hitch so far. The data transfer cable provides speeds up to 60Mbps (large files) when connected to a USB 3 port. The accompanying software installed properly and I was upgraded to the pro version automatically when I provided an email id. I have not encountered any vibration issues while copying files so far. There was no problem with warranty, it has been provided for 3 years from my date of purchase from Amazon. Registration was done online.
The reason that I am giving 3 stars instead of 5 is the very short data transfer cable provided by WD. It is only about 1 foot long and very inconvenient. I do not understand why a high end product like the Ultra series has to come with such a short data cable that it becomes inconvenient to connect it to my PC. The cable should have been 2-3 feet long.
