Best settings for RAID 0 with 2 x 500G ?

Hello,

I've to build a RAID 0 (Strip size 128KB) with 2 x 500GB HDD (465.7GB).
The RAID Manager (Intel Matrix Storage) offers me to build a volume with a capacity of 931.5GB.
I needn't a large disk space, 500GB should be enough.

Does it bring something (performance or other) if I build a RAID 0 volume with a capacity of 465.7GB only (instead of 931.5GB) with 2 x 500GB HDD?

Thanks a lot,
Chris

When you raid 0 you strip so you are combining the drive together so 2 x 500GB = 1 TB. The speed in RAID 0 is unmatched. I have been using this config since I built my first Q6600. Its very fast and with Intel usually very reliable as long you are using high quality drives preferable WD blacks or such server class HDs. Now I am sure you know this already but here is the bad news RAID 0 offers no data redundancy. Meaning that if one drive fails all data is lost. Now they do make recover tools for lost arrays, but nothing is certain. So I add a word of caution. Store all of your mission crit data on another drive or drives, or back up regularly. The best option if you can afford it is RAID 5 or RAID 6 which requires 3 and 4 drives minimum respectively. http://www.ibeast.com/content/tool [...] idCalc.asp will help you calculate raid sizes and http://en.wikipedia.org/wiki/RAID will explain all the different raid types. Some might recommend a RAID 10 that is an option to.
