Very good product with good value for money. Choice, order and delivery were very quick.
product conforms to my expectations my friend had checked the technical specifications of the product so I knew what I was going to receive and so no worries
I mainly use WD drives because I've never had any problems with them. The WD RED is quiet and doesn't get too hot. This is the first time I've bought a Red and I'm not disappointed. I bought it on the advice of the salesman at LDLC Claye, whom I would like to thank in passing. This team is great and always available to take the time to advise you according to your needs.
Western Red drive meets my expectations. Quick installation. Quieter than the Western Gold.
