- What counts as a 'large' raid 5 array? 2 answers
I've recently read this post:
tldr; It basically says that the error rate of a RAID system is tied to the hardware, and you need disks with a higher URE to make a RAID more stable.
We run a RAID 5 with these details:
- 6 x 2TB drives = 10TB useable
- URE <1 in 10^14 (each drive)
Understanding the article above I would like to check my numbers with someone else
- 10^14 bits gives me 12,500GB's per chance of a URE
- 12,500GBs / 10TBs = 1.25
Does that mean If one of my drives fails (lost 2 in the last 3 months) and I replace it, I have a 1 in 1.25 chance of getting a URE on one of my other drives?
I'm no expert so please feel free to tear this one apart and help me learn.
