Western Digital Purple
From Computing Classics Wiki
Western Digital Purple is a hard drive family created by Western Digital. It is designed specifically for surveillance DVRs and NVRs, and shares some similarity with the earlier AV-GP family. It was spun off into several offshoots, including a mainland China-exclusive family, a variant designed only for system integration and Purple Pro. It competes with Seagate SkyHawk and Toshiba DT01-V, DT02-V and S300.
History
The Purple family was first introduced in 2014.[1] In 2018, it was split into a retail and system integrator exclusive family, with retail models receiving a trailing Z on the main model number, as opposed to system integration drives keeping the previous X suffix.
