Reallocated Sectors Maybe?

While(Nick)Fork · July 22, 2017

Hey guys,

This is my first post, so I'm sorry if I did something incorrectly.

Anyway, about a 2 months ago I set up a new RAID server. Before I go too far, here are the specs of the setup:

Motherboard - ASROCK Thaichi z270

CPU: Intel Pentium G4560

RAM: 16GB (corsair I think)

OS Drive: WD Black 1TB

RAID Drives: 6 8TB Seagate IronWolf NAS Drives in RAID 5

RAID Controller: Integrated into MOBO

I have started using this server for storing light steam games that I don't mind taking a performance hit on. Recently downloads/allocation started taking forever/timing out, although other performance appears unaffected. Today I decided to check the array using HWINFO64 as it was one of the few tools that would display results for SMART data. As of right now 3 of the 6 drives are reporting a caution symbol (I have attached screenshots of the smart data below). From what I understand these are reporting 2 drives with 8 sectors reallocated and 1 drive with 16 sectors reallocated. With this I have a few questions:

Are these numbers something I should be concerned about? I do want to be able to depend on the data to a reasonable degree. I do not currently have a backup of this server as I can't afford to build another server yet. With that said, the truly critical data does exist somewhere else, but it would be VERY inconvenient to loose data.
Can these numbers be trusted? I have read some things saying that any smart data from drives in a raid array cannot be trusted, but these were pretty old posts.
If I really cannot trust these drives, will Seagate approve an RMA for this even though they still don't report a real failure? I cannot run SeaTools due to the RAID so as far as I know that's out. I really do not want to RMA the drives since from what I understand, I have to pay to ship them to Singapore and from the US east coast, that's not cheap. Not to mention that I will have to do it one by one if I hope to keep my data. I have never had to RMA anything, so this is all new to me.
Is there anything else that I am not thinking of?

Many thanks for any help provided (or attempted)!
