Question about RAID0 Storage Capacity

post #1 of 6
Thread Starter 
I just got my F3 500GB's back from RMA (all shiny and new ) and when I set the array up in the BIOS, it gave me an option to change the "Maximum Capacity" of said array.

What surprised me was that it gave me up to 1TB as the max. I thought when you RAID0'ed 2 drives, you were basically just mirroring (best way I can put it) the drives thus still having the array recognized as a 500GB unit. I hope this makes sense.

Anyone care to explain why it shows up as 1TB of storage?
Should I lower it from 1TB to 500GB?

The search engine on OCN is horrible at its job

Do you mean 1TB?

RAID 0 is striping. RAID 1 is mirroring. In a RAID 0 configuration you have access to 500GB x 2 = 1000GB of space. You only lose space in RAID 1.

When you configure raid 0, your data bits are alternatively written to each drive. So say you have 10101100, first '1' goes to hdd A then the '0' goes to hdd B, then the next '1' goes to A etc. So you get faster speeds, and double capacity.

Some say it is faster if you short stroke the array too 500gb.

When you say short stroke, do you mean actually partitioning the array or lowering its maximum capacity in the BIOS?

I can change it to anything right now since I currently have nothing on it.

I think either would work. Partitioning is probably better since if you need the space later on, you can use it.
