Hardware, Embedded Systems "Most applications do not deal with disks directly, instead storing their data in files in a file system, which protects us from those scoundrel disks. After all, a key task of the file system is to ensure that the file system can always be recovered to a consistent state after an unplanned system crash (for example, a power failure). While a good file system will be able to beat the disks into submission, the required effort can be great and the reduced performance annoying. This article examines the shortcuts that disks take and the hoops that file systems must jump through to get the desired reliability."

Very interesting and solid article. Of course it is only of an introductionary level but I can't imagine which systems administrator couldn't benefit from a read-through. Thank you for bringing it to my attention.

Well, Its interesting to me to understand the crappy code and config options in server applications that are designed around rotating disks. We only use flash pci-e cards for performance reasons. The real challenge is to then figure out how these options based on rotating disks affect flash that's still using a traditional file system that also has tweaks and options for rotating disks.
