I'm curious if IVS recommends any particular SATA RAID controller settings?

For example, I know you specify RAID Level 6.

But there are more detailed settings in the BIOS, such as:
(following are BIOS defaults)

Stripe Size: 64kb
Sector Size: 512k
Write Cache: Write Back
Read Cache: Read Ahead

Thoughts on these default settings?

Thanks in advance.

Cheers,

Boyd

I suggest following:

Stripe Size: 64kb or 256Kb
Sector Size: 512k
Write Cache: Write Back
Read Cache: Read Ahead

I strongly suggest to create more volumes in order to avoid to create volumes greater than 2TB. Also if Windows XP works very well with volumes greater than 2TB, we got a lot of critical troubles using these volumes in a LAN, some customers got unusual data loss.

best Regards
Roberto
