I want to maximise read performance using two drives under Linux software RAID.
Streaming large files (up to several Gb ea) & Postgres databases.
A RAID0 partition striped across the two drives should be quick, but there is a
(not too critical) issue of reliability with RAID0.
I know some hardware controllers will utilise both drives in RAID1 to give a
read performance comparable with RAID0, so I'll lose some space but gain data
security.
I don't know if Linux software RAID1 will read from both drives or not. I won't
be using a hardware RAID controller.
Any comments/advice appreciated.
