After having had a certain number of external HD with more or less success, I use this disc mainly to work on Final Cut Pro and the benefits are there: Very fast read access time Fast write speed No read / write noise No so no noise fan, having said that it does not really hot. No vibration. In short real profits compared to Seagate and other Scalable & Uppgrade available with SSD Lacie map A little more expensive than the competition but with no regrets.
