I'm curious, so for the sake of keeping things simple, if I were to store a single image file, lets say image.jpg, how would that image file be stored on the drives?
@airbrat Disks don't understand files - they just store blocks of data. If you saved image.jpg onto a PC disk - the operating system splits the file into small chunks - called blocks. A RAID controller can spread these blocks across multiple disks (and insert extra ones to protect against disk failure). The OS just sees the orignal blocks it created - and knows how to rebuild into the file when it reads the disk/ RAID group.
Great explanation of the concept. Thanks for sharing the video.
