I have had one of these for over two years now. I use it for everything, work (film footage, editing and music) and personal (storing photos, films, music). It has never crashed,frozen or lost/corupted any data in this time.
Yes it is a little louder than some other but I know many people who have used other good brands which are quieter, but after many months of intensive work they usually lose performance or stop working.
If you need a tough (it travels well) work horse get this.
