Solved! Formatting my hard drive

[coolcab]

I'm currently formatting (full format) a hard drive that is 14902.96 GB in size off 4 drives in a RAID 1+0 on the BIOS so Win 10 just sees 1 drive. When I started the format it was proceeding at a sustained (over a 30 sec period) ~150MB/s but 26 hours later it has completed 55% and now has a sustained speed of ~30MB/s.

So my question is will this actually complete or will it die? Also could someone explain why it is slowing down?

Thanks in advance

Will it actually complete?
No one knows. You'll just have to wait and see.

What 4 drives are these?

No idea. Where is it now?

What will this RAID array be used for?
Why the RAID 1+0?

currently at 63% complete
media storage
RAID 1 to safe guard from a hardware failure and RAID 0 to improve data access speeds for the file sizes

'media storage' really does not need the RAID 0 thing.
Just my personal opinion, based on a reasonably large media collection on my NAS.
