Any good as a nas drive?


Purple or CCTV enhanced drives are heavily write orientated, including the caching algorithms.

Also the error recovery algorithms aren't really there, as it's not so important in such a drive. Also it will confuse the NVR if the drive spends 50 seconds attempting to read data. It its use case, it's better to ignore it and carry on.

That's why red and purple drives aren't very interchangable.

I'm not sure, may be best to look further into it. I believe i've seen people seeking them out of their NAS drives on AVforums.
I know they're equipped to be 24/7 for eg cctv etc type drives so that would suggest to me that they're good enough but can't state categorically that they are NAS quality. Check that this isn't another WD drive that has gone SMR like the Red. Apparently it's the Red Pro that is NAS CMR now.

Probably fine in a nas, poss8bky a bit slower for random read but you probably wouldn't notice. However for a few quid more i would go red.

Ive got a purple drive in my nas box. Works a treat. Same mechanicals, different orientation towards writing. But no difference you’d ordinarily notice.

In May 2020, Western Digital was sued[67] for using shingled magnetic recording technology in its NAS line of consumer drives without explicitly informing consumers.[68] The lawsuit alleged that SMR technology is not suitable for the advertised use of the drives in a RAID array and intended to end any use of SMR in NAS drives.[69] Seagate, another data storage company and a direct competitor of Western Digital, stated that SMR is not suitable for NAS use and that Seagate uses only conventional magneting recording in its NAS-oriented products.[70]

In response to the controversy, Western Digital introduced a new naming scheme, in which "WD Red Plus" describes discs using conventional magneting recording and "WD Red" means SMR.[71]

I've never had an issue with either

It all depends on what you expect of your NAS ...


Been using a set of WD "blue" drives (shucked from external disk cases) in RAID-5 configuration for something around five years, with scarcely a hiccup (touch wood)

In my domestic installation with just a couple of users, and I don't read or write that much (speed is largely unimportant) , they seem to cope pretty well, I use RAID-5 for basic protection, and dump to cheap external disk every year or so,

I'm not quite so sure I'd be as happy using this approach if it was a business machine, used by many people.

Imagine 'whats the worst thing that could happen" and work around it. NEVER put complete trust in a single point of failure unless you're happy to sustain the consequences.

In direct answer to your question, I'd be happy to take that risk for my own situation.

That would depend on what your using it for, I had mine in my synology for surveillance station use only, I would not use these for normal data use as they are not designed for that.
