Why not RAID-0? It’s about Time and Snowflakes

Why not RAID-0? It’s about Time and Snowflakes by Steve Loughran.

From the post:

A recurrent question on the various Hadoop mailing lists is “why does Hadoop prefer a set of separate disks to the same set managed as a RAID-0 disks array?”

Steve uses empirical data on disk storage to explain why to avoid RAID-0 when using Hadoop.

As nice a summary as you are likely to find.
