How close was I?

Hardware

I'm near the end of an upgrade and I was interested in your opinion how close I came to oblivion. I felt like I was flirting with disaster for the last 1-3 months but I cannot decide on whether i was paranoid or not.

I built my freenas rig in late 2018 with 3x4Tb WD Blue disks in RAIDZ1 for total of 8Gb storage space with some janky-ass hardware with 8Gb RAM. The PSU was a generic 550W single-rail thing without even a bronze rating I kept up until now; at least it went into a surge protected socket. I upgraded to a Xeon E5-2658 (“v0”) proc. with 32Gb ECC RAM in late 2020 - it came with a generic chinese X79 board. After frying 2 pendrives I inserted some methusela SSD to serve as the boot partition. The SATA cables/ports were/are sus as hell, and my onboard LAN gave out.

Now (2025.07) I ran out of space and my WD Blue disks being 6.5years old, I bit the bullet and bought 4x8Tb Seagate Exos which I put into a RAIDZ2. I have 2 PCIe slots, one is occupied by a dedicated LAN card, and the other is a 6xSATA connector - I'm currently running headless :(. I bought a brand new multi-rail 650W PSU with a gold rating. Also some fans I am currently in the middle of installing.

I'm posting the SMART data of my old drives. I wonder what you think on a scale of 1 to 10, how dangerous did I have it until now, would my old setup have sufficed for 2-3 more years, or did I play russian roulette with my data for the last year or so?
