Raid Configuration?

I would like to know what's best configuration for a good web hosting service. Also, how exactly does it work. I heard you can use it for disk mirroring so if one disk fails you have the exact same that in the other raid hard drive.

Help is really appriciated.
 
"Raiding" is using multiple hard drives to write your data to. There are multiple types, but the two most common are Raid 0 and Raid 1.

Raid 0 is used to increase the performance of the server. Data is written to both drives in chunks - alternating between the drives. So while 1 is writing, the other is getting ready to write.

Raid 1 is also called mirroring. This is when the same data is written to multiple drives at the same time. This is normally used to increase the reliability in case of a hard drive failure. Raid 1 is a great way to increase the reliability of a server, but because the two drives are both being written to, it isn't protection against hacking or virus.
 
Most of my hosting customers prefer RAID 1. I rarely get any request for RAID 0 or JBOD array, which is pretty much the same.
 
RAID-1 is good for general webhosting. It only prevents against disk failure as any changed made on the RAID is made to both disks at once, so you still need a backup plan.

We use RAID-5 and RAID-10 on more specialized applications like fileservers or database servers. VPS server performance also greatly improves from using RAID-10 since disk I/O is oftentimes a bottleneck.

you should check out raid 10 or 6 - it is just as fast and uses less disk space overhead
 
We use RAID 1 and RAID 10. We have no servers using RAID 5 anymore. RAID 10 is the best for performance and redundancy.

RAID 1 is ok for if you only have two drive servers. RAID 5 is good if you only have room for 3 drives but always go with RAID 10 if your server/raid card/budget can support it.

you an your customers will be very happy.
 
It is always a question of pricing, but i would also recommend RAID 1 oder RAID1. Depending on the project and budget you have.

kind regards,

i forgot one thing: always look for harddrives that were made for 24/7 usage like Western Digital and Seagate offers.
