The helium-filled Western Digital Red WD80EFZX 8TB is a large capacity drive that plays the game by attempting to balance the parameters: Power efficiency, price, and performance.

The 8TB Red from WD is one drive to get excited about offering both performance and capacity in one solution, with a comfortable price point considering what it has to offer.

The new RED 8TB may not be a barn burner in comparison to Seagate Enterprise Capacity series, Western Digital’s own RED Pro or Black series, but overall it is still a top-tier performer.

Bought a pair of these to upgrade my RAID array from 2TB. They are only 5400 RPM so the transfer speeds aren't that impressive (only a pain when moving data to the array) but they run cool and quiet.

I bought 3 of these to put into an external USB 3.0 enclosure to run Windows Storage Spaces in parity mode. Installation & operation has been effortless. Before loading files I ran WD's comprehensive surface test...no flaws. I'm storing media files..

A drive of these specifications died, and so I started an RMA. BUT when it started taking days, I purchased a new one. Western Digital's RMA number generator was down, and when I called 6 days later to inquire about my RMA, they had 'lost' my RMA request.
