Intel ICH10R SATA RAID
expensive (requiring read-in prior to write, in order to
be able to calculate the correct parity information), or
similar to RAID-1 writes. The write efficiency depends
heavily on the amount of memory in the machine, and
the usage pattern of the array. Heavily scattered writes
are bound to be more expensive.
RAID 10
(Mirrored Stripes)
–
A RAID 1 array of two RAID 0 arrays.
† Strip Sizes:
Select the desired strip size setting. As indicated, the optimal setting is 128KB. Se-
lecting any other option may result in performance degradation. Even though 128KB
is the recommended setting for most users, you should choose the strip size value
which is best suited to your specific RAID usage model. The most typical strip size
settings are:
4KB
: For specialized usage models requiring 4KB strips
8KB
: For specialized usage models requiring 8KB strips
16KB
: Best for sequential transfers
32KB
: Good for sequential transfers
64KB
: Good general purpose strip size
128KB
: Best performance for most desktops and workstations
(2) Select the source disk
Then select the source disk that you wish to use and then click

to move it to the

field. Then click

to continue.
It is very important to note which disk is the source disk (the one containing all of the
information to be migrated) and which one is the target disk. On a RAID Ready
system, this can be determined by making a note during POST of which port the single
disk is attached to.
You can also use the Intel Application Accelerator RAID Edition utility before the
second disk is installed to verify the Port and serial number of the drive that contains
all the data.
