Just out of curiosity, why is that? just for the extra redundancy? Break this down for me like I am 4 please lol.
I understand the support is now included in some Linux distributions, but my experience was not great last time. You often encounter corrupted files, which is at least an improvement over nothing. However, the last time I tried restoring from ZFS was about a year ago, so it seems the support has likely gotten better. You might find RAID controllers that work with FreeNAS, and there are adjustments in FreeNAS that can help. If you prefer a dedicated RAID solution, Windows or another Linux distribution could be a good choice.
When a drive in your RAID setup stops working, the system is considered degraded. To bring it back to full operation, you must swap out the faulty drive and reconfigure the array. Beyond complete write failures, a major issue with RAID 5 is that only one extra copy of data exists. This can be problematic during rebuilds since each drive holds a single backup. Most consumer drives experience a BER (Bit Error Rate), meaning they occasionally miss one readable sector—about one per 10^14 bits. To rebuild, you must extract all data from the remaining drives, increasing the chance of another BER during the process. This risk is significantly higher than in RAID 6 arrays. I won’t go into the numbers, but the explanation is clear. In short, for a 6-drive setup, about 1 in 80 RAID 5 arrays fail during rebuild, compared to roughly 1 in 1982 for RAID 6. You can simplify things by using your motherboard’s built-in SATA ports and avoiding external RAID cards if possible.
You might want to stick with the built-in SATA connections and use the existing RAID settings. This approach is cost-effective and suitable for a modest home server, which means lower power requirements. For your setup, how much processing power do you anticipate needing? Would an i3 suffice or would a more basic i5 be better?
For optimal performance with ZFS, ensure ECC memory is installed alongside it and maintain at least 1GB of available RAM for each terabyte of storage.
That's quite a bit more memory than expected. I might need to look for a 16GB RAM package. Thanks a lot for your assistance!
FreeNAS offers free access but often performs poorly, making it hard to integrate smoothly with specific hardware or maintain stability after installation. It’s a major concern for handling large datasets, which is why many users switch to Synology instead.
