Hi,

My system shows a warning from the Western Digital Device Analytics and I want to replace it.
The Idea is to get a larger HDD to be future proof.

Q1: How full can I fill the HDD before the system gets slower?

My Idea is to add the new HDD to the storage pool and let it copy the data. Then remove the old (maybe defect) HDD.

Q2.1: Are there better options to copy the whole system?
Q2.2: Would it be bad when my HDD now is in SMR and the new one CMR? (I'd remove the old one after the data is mirrored)
Q2.3: Does it "just copy" or also deduplicate my data?

I tend to buy the Seagate Exos 7E10 ST8000NM017B or Toshiba N300 HDWG480UZSVA.
Q3: Is there a better option available in the same price segment? Any opinions?

System: DS218 DSM 7.1.1-42962 Update 4
HDD 1: WD60EFAX-68SHWN0
Used: 3,9TB (74% of the 5,5TB)
Pool: SHR, btrfs

WDDA: WARNING:

do not mix smr and cmr drives in a disk array. Bad things can happen. I would power down the NAS, remove the suspect drive, attach it to a PC or MAC and run WD drive diagnostics as a secondary check.
 
This 'warning' appears to be caused solely because the HDD has reached ~3years of life. The important metrics of your SMART data all appear to be fine.

There was another post here recently featuring the same 'warning'; it appears that WD are now using the SMART system to 'warn' about / upsell HDDs that are running fine but have reached the end of an arbitrary 3yr warranty period.

I would ignore this particular warning & keep using the drive until one of the more meaningful counters increases (i, 5, 196, 197, 198).

@Coop777 is absolutely right that in general its a bad idea to mix SMR & CMR HDDs in the same array, though this isnt why your warning is appearing.
