![]() Drives count their spin-up/down cycles and power-on hours. smartmontools in daemon mode - it is not a perfect monitoring solution due to the nature of HDDs but can give you an indication of how much life the drive is expected to have. In any case, even with a factory setup, they're designed to last 3-5 years. At the same time, they're probably imagined to spend less time in operation than powered off. Use with care though.Īs the drives you have are out of an enclosure, they're intended to be powered on and off more frequently than a desktop drive. ![]() If you know you're not going to be using a disk for a while, you can use hdparm -y to manually instruct the disk to spin down. Add noatime to the options field in /etc/fstab. It's worth modifying the mount options to disable atime - Linux by default updates the date on any file that is accessed, even if it's not modified, and if you're just browsing the filesystem as it's cached in memory, this can cause the disks to spin up unnecessarily. If the latter, they can be set to spin down fairly aggressively to save power. You mention the workload is light as a second-line backup device - are the drives going to be written to as a steady trickle, or a big burst all at once and then silence for the rest of the day? If the former, keeping them spinning (disable power-saving) is probably best. ![]() It's just good practise in an enterprise setting to make them last longer (10 years is easily possible with current HDDs). Consumer drives will spin up and down every day for 5 years or so without complaint. However, depending on your use case, there may be compromises for power use and heat production - it's not a small number of spin-up cycles, it's tens of thousands before the drive would start to encounter mechanical faults. They like to be kept spinning as much as possible, and also kept relatively cool (around 30'C). Spin-ups and downs are the most wear-intensive parts of a disk's life. r/HomeNetworking - Simpler networking advice. r/pfsense - for all things pfsense ('nix firewall) Might be able to find things useful for a lab. ![]() r/hardwareswap - Used hardware, swap hardware. r/buildapcsales - For sales on building a PC r/linux - All flavors of Linux discussion & news - not for the faint of heart!
