Western Digital's high-performance Black and NAS-oriented Red Pro drive families welcome some new members today. Both Black and Red Pro drives are now available in 5TB and 6TB capacities, and they're all equipped with 128MB of DRAM cache and 7,200-RPM spindle speeds.
WD says the 6TB Black offers 29% faster maximum throughput than the previous 4TB version. Also, if you're wondering how the Red Pro drives compare to regular Reds, here's the skinny: they spin faster, at 7,200 RPM versus the "IntelliPower" rotational speeds of their non-Pro brethren. They also have double the cache—128MB versus 64MB—and they're claimed to have enhanced vibration prevention measures, along with extended factory testing.
All of these drives are covered by a five-year warranty. The Red Pro 5TB and 6TB drives carry suggested prices of $269 and $299, respectively, while the Black versions will set you back $264 and $294. The company says the drives are available today at "select US retailers and distributors."
