Not better than RAID 10. RAID 5 has compression (not good for write intensive dbs.) while RAID 10 is just striping and mirroring and no compression(eats up half the disk space though). So its a trade off between space and performance. :DQuote:

Anyway, Raid 5 in an external storage with high memory cache can manage thousands of records as if it is an ordinary disks.
But still I agree with the freelist configuration though.
:D
I am aware of that simply_dba. It was RAID 5 that was brought up here, and from your own word "eats up half the disk space though"Quote:

And indeed it is a trade off between space and performance.;)
Does raid 10 have data protection too?
Oh Yes m'luv :DQuote:

look here for more information.
http://www.9to5computer.com/atto/Rai...d-Striping.htm
so which one is better? raid 5 or raid 10.
If both offers data protection, which one gave up more space?
coz normally protecting data will cost u more disk space. and
more disk space means more cost in i/o performance.
RAID 5 is always better except when it isn't. How about using google?
Ok thanks hun, i take ur word for it:)
So simply_dba u must forget raid 10:p
Heck no hun:) !!Quote:

RAID10 will give you faster performance than RAID 5.Please see my previous post on that and also the link I supplied.:cool:
But honeyyyy! u said it eats up half space of ur disk? So if i have
100gb storage i can only user 50gb? what a waste.:rolleyes: and how
can it be faster when u write duplicates mirror copy:p
That's what I said m'luv! it's a trade off between disk space and performance.And Raid 10 has certainly higher performance than raid 5 in terms of disk write.You musn't forget that Raid 5 has compression.Quote:

However there something new over here which give you combined benefits of Raid 5 and Raid 10 read on and luv me
