It's been a while since Western Digital updated their Black series of HDDs, with their 4TB release taking place over two years ago. I'm happy to say that for those looking for a massive HDD suited for holding that enormous games folder too large to fit on your SSD, your wait is finally over, as today WD has updated the Black line to include 5TB and 6TB capacity units.

The Black series introduced that nifty dual stage actuator technology nearly five years ago, and has added a few more bells and whistles along the way. These new models include a 128MB cache and run on dual-core processors.

Along with that news also comes an update to their Red Pro series, which was also limited to 4TB in capacity when they launched last year. Red Pro models will now also include 5TB and 6TB units, so those wanting the most performance and lowest response time from their NAS can now also enjoy that performance at a 50% gain in capacity.

The new 6TB Red Pro also includes a 128MB cache and can peak at 214MB/sec (at the start of the disk). Also included in these is WD's NASware 3.0 firmware, which is specifically tuned to enable packs of these operating in packs while minimizing the effects of vibration on performance.

The 5TB Black comes in at $264 while the 6TB comes in at $294. The Red Pro's come at only an additional $5 over the Black, respectively (small price to pay for better compatibility with larger arrays). Both the Red Pro and Black carry a 5-year warranty.

Press blasts for the 5/6TB Black and Red Pro appear after the break.
