Is RAID 1 enough?

[Guest Sternkreuzer]

I am considering putting RAID 1 on the new machine I am building, with XP

Pro.

 

Reading the documentation on the Intel motherboard it seems one needs to do

the <F6> tinkering with the BIOS at the very beginning of the installation of

XP Pro.

 

I like the RAID 1 concept, but what happens if the motherboard fails? Is

there a danger of losing all the data on the mirrored disks after replacing

the motherboard? It seems one would have to go through the <F6> procedure

again so the motherboard accepts a RAID configuration. Does that force a

Clean Install??

RAID is REDUNDANT DRIVES, it's not a backup method, it's not a data

security method, it's not about data, it's about having a second (in the

case of RAID-1) drive to continue operations of the other drive fails.

 

RAID should NEVER be considered a backup method for data.

 

If your RAID Controller Fails - such as a mother board, there is a good

chance that your RAID will be lost.

If the RAID controller fails, wouldn't he be able to easily replace

the controller without any data loss?

Not always. Some will put their own structure on the drive, some

controllers won't allow you to add drives with data already on them to

the controller without wiping it, etc....

 

RAID is for hardware, not a backup. You need a BACKUP if you want to be

able to restore data.

No RAID configuration is a replacement for doing regular backups. I don't

have any experience with on-board RAID but I had a discontinued RAID card

fail and had to replace it with a newer model. This required a fresh install

followed by a restore of all data from backup. I would imagine if your MB

dies after its production life is over, you will have issues unless you can

find a used replacement. Long story short, don't depend on RAID as an

alternative to backups.

My experience is as follows: if the Intel motherboard fails and you

replace it with the same model, the raid will recover and be usable. I

have replaced my motherboard and the RAID survived. (Note, I had both a

RAID 0 for as the boot disk and a RAID 1 as a data disk and both survived.)

 

The answer to a question you didn't ask: Yes, it is necessary to backup

a RAID 1 just like any other disk.
