Negovorim opcenito nego iskljucivo u NASu.
Imam ja greenova koji su stari 10+ godina pa rade ali u NASu kao sto rekoh nisu trajali.
WD RED je NAS disk, GREEN je storage, BLACK je performance desktop, BLUE je desktop sredina, PURPLE je surveilance A/V itd. itd..
EDIT: evo jedno od kracih objasnjenja.
"If your NAS is going to be dedicated to recording video from your IP cam, the WD purple would work just fine. The Purple is "Optimized" for recording Video. (Writing data) A Network Video Recorder is basically a NAS for video and the WD Purple is used in those. But if Your NAS Is primarily for storage of Critical Data files, and IP cam video is just something else you want to store, It wasn't designed for that. Something like the WD Red pro has (according to their spec sheets) 1,000,000 (hours) MTBF (mean time before failure) rate and lists 600,000 Load/Unload cycles. It runs at 7200 RPM and has a 5 year warranty. The Purple drives don't list a MTBF, but list 300,000 Load/Unload cycles. Half that of the RED pro. Under RPM the Purple simply states "IntelliPower", but Internet sources say its closer to 5400 RPM, and it has only a 3 year warranty. And the Red is optimized for Read AND Write algorithm's, (and remember a faster RPM equals less lag in read/write scenarios) which would be a more typical NAS file storage type, one the purple isn't recommended for. Although both are designed for 24/7 usage, Most users don't consider security video critical data, and is written over fairly often so the lower specs aren't as critical to them. Ideally you would have separate NAS for your IP video and your Data File storage
