You pay your electricity, but you pollute _our_planet.
As I said... I spread my filesystems across several small disks. This GREATLY reduces disk-head wear... not proportionately, but in fact, geometrically.
Not true.
Absolutely true. Reduction of race-conditions in file access in different parts of the directory tree. Executables are not loaded in their entirety... the kernel loads only some pages into memory as needed...because of this, the disk-heads can be bounced around not only among files in the same directory, but even from /etc to /bin to /lib and /usr/lib...not to mention /tmp and /home Keeping the total directory tree spread out reduces the number of times that a disk-head is removed from the middle of a file, only to be returned to it once again...instead, there is a much better chance that the disk head will just stay in place (as R/W activity happens on other disks) and the next read just resumes where it left off.
Ask your HD manufacturer. Once we asked Seagate about the life expectancy of disks continuously on, or automatically standed down (not spinning). The said: "the same, no effect".
You didn't ask about reduced disk-head movement, and the life span of reducing it by spreading filesystems over more disks.
In fact, you are increasing the overall incident rate by spreading your data over several smaller disks.
Then why am I at the point where I now get rid of disks NOT because the have worn out, but because they are now too small to be of any use. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
