Inquiry Regarding WD Black HDDs – CMR vs. SMR and Use Case Considerations

#3
(CMR vs. SMR)
Got it. The WD Black 10TB (WD102FZBX) and WD101FZBX are both CMR, so no concerns about SMR.

(24/7 Use)
WD Black is built for performance, not continuous operation like NAS drives. It can run 24/7, but for RAID or always-on setups, WD Red or IronWolf would be better.

(Cache Size)
The 512MB cache version offers slightly better performance, but for media storage, system RAM plays a bigger role. If the price is the same, 512MB is the better option, but the difference isn't huge.

I have two follow-up questions for you.

If I use a WD Red drive independently (not in a RAID setup), could its TLER feature, which prevents the hard drive from entering a deep recovery cycle, become an issue in the event of a failure? Would it affect data recovery or error handling differently compared to a drive without TLER, like the WD Black?
