WD Reds, which seem to be very popular choices for NAS setups, now have two 10 TB versions fans can choose from: the standard Red drive, which comes with a 5400 RPM spindle speed, and the Red Pro, which offers better performance at 7200 RPM. I like the idea of a cooler-running drive, especially when it comes to simple media storage, but the Pro version does carry a more impressive workload stat and longer warranty. No release date is listed, but Newegg suggests 5/30 for the Red ($399) and 6/17 for the Red Pro ($459). ...Western Digital is refreshing its Red and Purple lineups with more advanced drives offering 10 TB capacity and using seven 1.42 TB platters. The new WD Red and WD Red Pro with 10 TB capacity are based on revamped 5400 RPM and 7200 RPM HelioSeal platforms that can support a higher number of platters. The drives also feature increased areal density and 256 MB of cache, enabling ~17% higher sequential read/write performance compared to its predecessors, as well as a lower power consumption compared to previous-gen helium WD Red hard drives. Other than that, Western Digital does not really disclose the feature set of its platform for helium-filled HDDs for NAS applications.
