The problem with such categorical statements is that no definition of
"best" is given. Read the series on Inside SQL Server from MS Press,
you will develop a much more complete idea of WHEN hardware
RAID is preferable to software RAID and when it is not.
I haven't read this and can only refer back to personal experience. There
are not many instances I would choose software RAID, if there was a
hardware RAID controller sitting in the box.
You will have to go beyond the naive understanding that most people
have of this topic.
And this is why I am prepared to accept there are times I may consider
software RAID. I can't see yet when, but I will concede it may happen.
Hardware RAID is likely faster and isn't always a viable choice sometimes
when software RAID will do the job (and sometimes cheaper.)
Depends on the requirement and the technical constraints.
I buy very good RAID controllers off EBAY for about US$25-50. If a
client has SCSI hard disks, I will normally suggest RAID0 as a minimum.
With IDE RAID, I generally suggest running the drives on separate
controllers for speed, RAID0 or RAID1 most of the time. If someone
wants RAID5, I think I have always gone SCSI, 3 but usually 4 or
I wrote an explanation to you, Herb, about the Log Off Users problem.
I have noticed a lot of posts are not coming through, so will check again
tomorrow before reposting.
