Well, your not understanding what i am saying,
Hypothetical
2 Harddrives 500gb Each
Each Harddrive has 2 platters 250gb each
so you create a raid partition of 250gb, then create another 250gb Raid Partition,
if you know the platter size ie, Full size Divided by Number of Platters, then you create a partition of the size of each platter, its going to use them incrementally
so you raid the 2 harddrives together, Platter 1 from each harddrive is its own raid Partition
PLatter 2 from each harddrive is its own Raid Partition, so you now have 2 harddrives with 4 partitions in a Raid 0, ok
so think about it, you have HD1 PLatter 1, and HD2 platter 1 storing the same information with its own 2 heads reading the information from 2 separate drives, faster,
RAID will use each drive to store the same information so that you can read it from 2 places rather than 1, doubling the read threads and doubling the speed.
i know it is possible, i have done it on servers before i was just wondering if anyone has done it for a more enthusiast application, to see the benefits.
The harddrive is written to however you tell it to write to it. Striped, mirrored, by cluster size ect..
when you are creating a Raid Partition you select the size of partition you want to create, if you are using 2 identical drives with the same platter size, then you figure out how many platters you have and what size they are in Kb then create your raid partition that size, you create a separate raid partition for each platter depending on the size, it will use it incrementally so if you enter a partition size of 250gb and each platter is 250gb then thats all its going to use, because you said to use from 0 to 250000mb first, all of witch is contained on the first platter, then if you create another portition thats 250 then it just so happens to land on the second partition, this isnt a setting thing its a math thing if you know the platter size then you can get the RAID partitions to land just right so that Raid HD1 is on the First platter of each drive, then RAID HD partition 2 will be on platter 2, is this a better explanation?
