Got tired of SD cards dying in my TrueNAS server, so I snagged a pristine 20GB Intel Enterprise SLC SSD for ~$4.80 (₹400)
After my SD card boot drive corrupted for the last time, I went hunting in local markets for a cheap, permanent fix for my budget server (Zebronics G41 / Core 2 Duo / 6GB RAM running TrueNAS SCALE 24.10).
Managed to pick up an Intel 313 Series 20GB SLC SSD with hardware Power Loss Protection (PLP).
Hooked it up and checked CrystalDiskInfo:
Total Host Writes: Only 49 GB (practically brand new)
Power On Hours: 4,625 hours
Health: 100% Good
TrueNAS SCALE installed cleanly, taking up only 2.77 GiB of the 18 GiB usable space, leaving ~15 GiB free for logs and future boot environments.
Moving the OS/middleware dataset from an SD card to enterprise SLC flash over SATA instantly eliminated random Web UI delays and made SMB directory browsing surprisingly snappy. Definitely one of the best budget upgrades I've made for this setup!
