Spinning off from this thread: https://bobistheoilguy.com/forums/threads/weird-hard-drive-issue-questions.386355/
I have an old PC acting as a file server. One SSD, three platter hard drives, two optical drives, all SATA. The case itself is well ventilated but it sits somewhere that isn't. Been using the onboard SATA controllers to minimize power consumption, but @SupremePossum suggested getting a better HBA and now I'm wondering if there's a way to add reliability without adding significant power draw.
So far, if I exclude everything that looks to my noob eyes like a cheap consumer-grade product (e.g. the Highpoint RocketRaid 640L – correct me if I'm wrong in that assessment), everything seems to need over 10 W – e.g. the LSI SAS 9200-16e at a stated power draw of 13 W. I'm sure that's peak and not what it'd actually do in my application, but they don't list a minimum or nominal figure. I'm assuming some of that would be offset by the fact that it'll take a little load off the CPU during I/O ops, but not enough to make a dent in power consumption or temps, right? The onboard Marvell chip I'm using now is specced to draw <1 W...
I'm sure I've already put more thought into this than it's worth, but it's been a while since I've had an interesting left-field computer question to sink my teeth into.
Anyway, anyone have any suggestions?
