There is no loss to the harddrive if there is a power failure i hope?

And many of my frnds have been using raid0, and havent complained anything about data loss, even if there is a power outtage etc… care to comment on whether the data loss is merely a chance, or is it must in case of power loss?

Sorry about that. It must have been a late night when I wrote that guide. I had it all backwards. I fixed it.

Thanks for pointing that out to me.

The whole point of the cache is to commit data in larger chunk at once to the hdd so that it does not perpetually change location write a few bytes here and there. Cache is only here because it makes things faster.

The advanced performance certainly means: use a bigger cache. Which in turn means that actual physical write to the disk will happen less often (= better performance as memory is way faster than any mass storage media). But if you get a power loss there are more chances that you’ll loose cache content before it gets written to the disk.

I don’t think anyone could stand using a multi-threaded OS if it were to deactivate the disk caches.
