I know you guys are discussing servers with hard disks, but what are
your thoughts about systems without disks, so-called embedded systems?
Embedded these days doesn't mean small and probably does mean they are
running a general purpose OS like Linux. I use some with a couple of GB
of RAM, but their only "disk" is flash. Writing to flash is not only
slow but also invokes the wear-leveling algorithms and, ultimately,
reaches the point where the flash is worn out. One tries to avoid any
writes. The smaller the "swap" space, the more concentrated the writes.
So, if you say that a system without any "swap" misbehaves, how does a
system like this survive?
