Review on West Digital 4TB Surveillance HDD - 5400 RPM SATA 6 Gb/s 64MB Cache 3.5in - WD Purple40PURZ (Old Version) by Bhavin Patel ᠌

Nowhere in the reviews is not indicated a very important point! The Purple series is optimized for video surveillance systems, everyone knows that. There is one caveat! The disk firmware implements error skipping during recording, since the continuity of recording when used in video surveillance systems is a priority over the integrity of files. That is, any random file can be recorded with an error, and this is not necessary for us, ordinary users. Therefore, for normal use, it is better to consider Blue and Red series hard drives, and it is better to leave Purple with this nuance only for video surveillance.
