When I first started writing for TweakTown, hard drives just broke the 4TB barrier and SSDs were just getting started. Now the hard drive market has completely changed into an all-out battle for who has the highest capacity drives. Seagate is now shipping 12TB IronWolf and Barracuda solutions that we will be looking at in an upcoming article, and up to this point we do have 10TB Red, Red Pro and 10TB WD Gold samples in-house with rumblings of 12TB solutions very soon. The WD Gold was announced and launched mid-2016 with 4TB, 6TB, and 8TB capacity options. It takes over where the RE drive left off, and since then, WD has expanded the lineup to include 10TB and 12TB solutions. All WD Gold drives feature a 7200 RPM spindle speed, the latest generation of electronics part of which includes enhanced RAFF-technology that monitors the drive to correct linear and rotational vibration in real-time along with Dynamic Fly Height technology to monitor and adjust each read/write head to ensure consistent performance and of course, RAID-Specific TLER.
