The drive itself works well, but being a large 4Tb sitting on numerous glass parents. These glass platters need more power to run off a standard USB3 port. Sometimes it works, then it drops off due to a lack of power. This drive requires an external power supply (which it cannot accept), or a high power USB port.

This drive is very quiet and works reliable on modern OS/USB3 ports but the write speed of max ~120MB/s is a tad slow especially for a 4TB disk - transferring big files/recordings takes a while! The included usb cable is very short maybe 1 foot long - bring a longer cable if needed.

Quiet a few years back I moved away from Seagate to Western digital as there products we're not lasting under heavy data transfer usage.
About 2 years ago I decided to give them another try after years of departing from their products and the 4TB portable Hard-drive has not let me down to date and still under high data transfer and usage rates.
Quality seems to have got somewhat better but the real test now is time, so far so good.

Great product, using it currently as a replacement from my previous Seagate 2TB Expansion Desktop and have had no issues with it thus far. Loving the usb cable and not having to use a power cord as well. Very convenient for my job as well as I can just chuck it in my bag.

You can never have enough space to store your important files but for this value priced hard drive you cannot go wrong. Fast USB3 interface, USB powered (no need for a external power adapter), compact and plug 'n' play if you are using a Windows PC (can easily be reformatted for Mac computers)
