Seagate or WD

Nizar77 · February 13, 2023

Hi, I'm looking for 12TB or 14TB Hard drive, so which one is faster and more reliable and less noisy?

Seagate HDD NAS 3.5" 12TB ST12000NE0008 Ironwolf Pro

or

WD HDD 3.5" 12TB S-ATA3 256MB WD121KFBX Red Pro

or

WD HDD 3.5" 12TB S-ATA3 WD121KRYZ Gold

I read that "red pro' clicks every 5s, and the 'Gold' is very noisy ... what about Ironwolf Pro?

what is your opinion?

Thanks

All of them is reliable and every mechanical disc make sound. why you need 12Tb of storage if you care about that data even how good the storage is you need proper backup.

if you want reliability but not at the cost of server grade disks WD make excellent drives for security systems. WD purple are specifically designed for Surveilance and high durability.

I think OP is taking the "buy most reliable thing" motto of car people, but with data the dogma is and should be different. TREAT EVERY STORAGE AS IF ITS UNRELIABLE.

Also, all 3s are good, its definitely a buy-the-cheapest ordeal to me as HDD performance have peaked at this point.

One really important concept of NAS drives is that they won't necessarily be more "reliable" than regular HDDs - they're designed to keep RAID array alive and consistent - as such they'll fail more but they'll fail more gently to avoid data loss / corruption because they assume they work in array so "probably storage will work without me". I'm using 14 x 2TB IronWolf and and IronWolf Pro in my storage server for many years 24/7 (When I say non-pro-IronWolf I actually mean Seagate NAS because some of them are so old, I obtained them before rebranding). And they're ok. Only one failed on me and it did it really gently (turned itself into read-only mode so I could actually dump all its data to new drive, checked all checksums - no data got corrupted). I'd say ability to fail reasonably is just as important as reliability itself because at the end of the day - disk is just disk - you'll replace it. It's always better to just replace hardware than loose data. The worst thing that may happen in NAS drives is when such drive won't realize it's damaged and will start returning corrupted data that will eventually propagate to other RAID members during parity calculations and your data will get trashed for real.

Definitely solid drives that behave the way they should.
