How to prevent load cycle (head parking) from increasing so quickly (WD Blue HDD) in a Synology DS918+?
Hi,
I recently purchased a DS918+ and shucked some external HDDs to add a pair of WD Blue 5 TB drives (WD50EZRZ-32RWYB1) to the DS918+.
After doing some reading, I am worried about the load cycle count increasing very rapidly because the WB Blue HDDs park their head after 8 seconds (and this value cannot be changed using wdidle for Blue drives, correct me if I'm wrong?).
My S.M.A.R.T. info so far:
WB Blue 5 TB Disk 1:
* March 20th: 44,389 load cycles
* March 30th: 58,585 load cycles
* increase of 14,196 cycles in 10 days = 1,420 per day ~ 1 per minute
WB Blue 5 TB Disk 2:
- March 20th: 14,265 load cycles
- March 30th: 28,453 load cycles
- increase of 14,188 cycles in 10 days = 1,419 per day ~ 1 per minute
(I also have some HGST 10 TB drives in the DS918+ that have incremented their load cycle count by a total of 10 (each) in the past 10 days, so it seems those NAS-rated drives are working flawlessly.)
I am looking for a solution to prevent the head from parking so often and causing the load cycle count to skyrocket. From Western Digital's documentation, the drives are only tested to 300k load cycles. I don't think wdidle can be used for WD Blue 5 TB drives from my google searching.
Is there an option in Synology DSM to prevent the drives from parking their heads so often?
Any suggestions/solutions are greatly appreciated, thank you!
