What is faster - Raid1 or Raid5?
Posted on 2004-09-09
Got a big database (approximately 20Gb). Software allows to split this database between several logical/physical drives.
I have 6 SCSI drives.
Thinking about 2 ways organizing that:
1) Create 3 Raid1 arrays out of my 6 hard drives. Split the database between those 3 arrays.
2) Create 2 Raid5 arrays out of my 6 hard drives. Split the database between those 2 arrays.
Need help choosing the best way out of this two.
The goal is to have the fastest possible way to access database from clients.
Any calculations or link to page about how to calculate the total speed for each variant will be the best help.
