Hello, All!

Is there a highly thought of site that discusses RAID0 setup (do's/don'ts,
etc.) for newbies like me?

Thanks.

My personal advice: Don't use RAID 0 unless you are prepared to
loose the array.

That said, thest the block-size with your actual usage pattern and
tune it to maximum performance. Depending on the set-up different
block-sizes (sometimes called stripe-sizes) will give different
speeds. Also make sure to tune the filessytem to the block-size if
possible, although that is less important.

Before you do all this, think about what you actually want and
whether RAID ) will/can give that to you.

How the tunig works in detail and whether it is possible
depends on many factors, among them the OS and filesystem used
and the access pattern.

For Linux the RAID HOWTOs are a good place to look.

Colonel,

All we have around here are RAID 0 arrays. Some are 4 years old. We use SATA
and PATA. No problems with any of them!!
I do not recall a good discussion beyond what you already know. I guess that
every system is a little different so it is difficult to do a cook book
discussion.

Remember that these arrays are set-up by you and the BIOS. Once the array is
installed it looks like a new drive and has to fdisk'ed and formatted and
partitioned if want more than one partition.

Installing Windows XP on an array is the easiest.

This is a good place to ask specific questions.

I'm closing (ever so slowly <g>) on a decision.

Thanks.

Yup, better not use harddrives at all unless you are prepared to
loose the data.
