With our enterprise storage (in usable Petabytes, not raw), we replacing atleast a full car load of high performance HDD(s) every Sat & Sun. We tried changing brands etc - no difference. These enterprise storage all in RAID-5/6 configurations. Nowadays the HDD failure rates quite high compared to those before IBM sold away all their patents and HDD manufacturing facilities a few years ago.

PetaBytes !
Sweet Jesus, I am still trying to save bits !

So just be prepared for HDD swap-outs during yr RAID's lifetime ... we lucky coz under maintainence contract so flat fee for the client but the vendor kena.

Under RAID-1, was like under 50 a month per Peta before we went to RAID-5/6 with the new enterprise storage systems.

I have been praying very hard for HDs not to failed and it works till now.
Later , I have no idea. Perhaps ask me tomorrow.

Of course , there are a few dead HDs from my PC. These dead HDs are most of the time caused by improper shutdown while it's in write mode.

U can also get "dead" HDD(s) if they have been in continuous use for a while eg power down for maiintainence but won't start up after the maintainence over.

I just informing of the experience dealing with enterprise storage in mission critical environments across the world. Up to you how you wish to implement or run your own facilities.

I have only 2 NASs , no Server. Both NASs are on RAID 5 , 24/7, and daily incremental backup each others since each has it own purpose. So even if 2 HDs in same NAS failed , I still have a full back up on other NAS, nonetheless , if in the case of 2 HDs each in 2 NASs failed at the same time , I am a dead meat.

It's all about how I want to manage the risk.

Go to SLS 5th floor.
Ask for Synology 1819+ and 8x 14TB WD Red. They accept NETS for NAS but cash for HDs.
Go down one floor lower,  grab an UPS.


Done.



Addendum.
Joke aside , if you are looking for Synology NAS but can't decide or don't know what are the models :

Just read this :

Why??    I just want to buy 12 X 10TB, run RAID6 and live happily ever after, like the last 20 years.  What's wrong with that?

(Audio)


There’s a big difference in Drive capacity from 20 years ago and now…

Let’s do an experiment shall we? Pick one of your current QNAP(?) RAID6 array (>4TB drives?), pull out one drive and insert a new one; tell us how long it takes to rebuild… (don’t blame me if you end-up with an actual drive failure during rebuild, so backup your data first ;D)

At home I scaled-down from an Apple XServe/QLogic FC switch/Promise SAN array, down to just a Synology NAS (RAID10, with AWS backup) for my Photos etc., and Melco (RAID1) for my DSD & PCM High-Res files. Everything else streamed over the ‘net :)
You'll never get to heaven with a smile on your face from me.
