"WD Purple surveillance-class hard drives are equipped with AllFrame 
technology which works with ATA streaming to reduce frame loss"
This article specifically talks about the Purple disks and how ATA streaming 
is enabled. 
http://www.hardware-boom.com/review-test-drives-wd-purple-2-4-6-tb/
The drive has to have the feature ENABLED at a command level PER WRITE. It 
is entirely a firmware feature.
IE -- These drives are 100% safe* for normal operation and wont randomly 
drop data. The ATA streaming commandset must specifically be used at the 
time the data is written.
