comment How to power off a hard drive to essentially “hot swap”
If the machine isn't designed for hot-swapping then it may not be safe to hot-swap the drive.

comment What is the best hard drive for random-reading small blocks
Although new SSD have TRIM, which should help this problem, by (AFAIK) allowing a background operation to clear up the pages.

comment UDP traversal through router automatically without router port forwarding?
Actually, while a pure NAT device blocks incoming connections by accident (having no-where to send them), many NAT home routers now explicitly claim to be firewalls.

comment Linux: how to explicitly unswap everything possible?
I'd recommend just allowing normal operations to swap in what is actually needed, rather than manually doing anything.

I agree with this answer - you should probably leave normal operations on the machine to swap in what is actually needed.

@Juliano - Hence my last sentence - If you don't actually have enough memory then the OOM killer will get you.

I'm not sure killing swapoff will actually stop the operation. Depends how it's implemented.

comment Linux: how to explicitly unswap everything possible?
I don't think program memory vs. cache is the issue here - I think it's application memory vs. unused memory. And I don't think swappiness will affect that.

comment Linux: how to explicitly unswap everything possible?
I don't think even a swappiness of zero will cause pages that are already swapped to be explicitly brought into main memory?
