the one to get

Wish I'd bought a few of these earlier. They are genuine and come well packaged. If the prices drops, I'll probably buy more

My Red drives have exceeded my expectations

I have been using WD Red and Red Pro drives in my NAS for years now. This most recent purchase of a 12TB Red Pro was to replace an older 6TB Red that had a lifespan of 10 years. So, you could say I have been very satisfied with using WD Red drives in my system. It is a slow progress to move up from 2/6TB Red drives to 8/12TB Red Pros. All of my Red drives have well exceeded their warranted lifetimes. NO drive has failed in under 8 years of life and some are going on 10 years of life. My overall experience with WD drives has been very satisfactory and I will continue to use these as I upgrade and expand my system.
