My book "Patterns in Data Management" is now available both as an ebook or a print book (with color graphics!). See: http://amzn.to/1Ts3rwx This book is not a standard textbook on database techniques. This book was written extending and complementing preexisting educational videos (including this one).
Why should I worry about hard disk failures? What is the core idea of RAID? What is the impact on performance of RAID 0? Is my data safer by using RAID 0? What RAID 1? How much space does it waste? What is the difference of RAID 4 and RAID 5? How many disks do I need for a RAID 4 or 5 system? Which sequential read performance can I expect in a system with n disks? And which write peformance? How many disk failures may a RAID 4 or 5 system survive? What is the difference of RAID 6 compared to RAID 5?
