The main difference between WD Red Pro and WD Red is WD Red Pro spins at 7,200 RPM vs. 5,400 RPM for the Red, giving it a slight edge for performance-oriented professionals. Both join the other more than 15 million helium-based drives WD has shipped to date.
WD is finalizing compatibility testing with a number of leading NAS system providers. WD has published a compatibility list of WD Red-qualified products and manufacturers here.
The new WD Red and WD Red Pro 10TB hard drives are available now and feature a three-year limited warranty for the WD Red 10 TB and five years for the WD Red Pro 10 TB. MSRPs are $494 and $533, respectively. More information is available at https://www.wdc.com/products/internal-storage/wd-red.html.
