You can estimate the RAID characteristics using this RAID calculator. Usage
instructions are simple: select the desired array layout, then enter RAID
member disk capacities into the corresponding form fields. The rest is done
automatically.
For more information about RAID and RAID levels, please refer to
RAID 101.
Notes
Write speed of a RAID 5 depends upon the controller implementation
heavily. The estimation of a write speed is thus not provided for a RAID5.
Setups involving more than two member disks in a RAID1 (Mirror) array are
allowed but rarely used. Additional backup ("shadow") disks provide additional fault tolerance
at the cost of storage space overhead.
RAID10 survives any single disk failure and a half of double failures
(depending on the assignment of the failed drives).
My brother has a smart media card which was taken by an old digital camera.
He could not get pictures downloaded nor print them directly from the camera
(he can see them on the camera screen) and photo shops in Japan had no success either.
Well, I told him that I can try here in the U.S.
I could see files but downloaded files looked corrupted.
I took it to a professional photo shop but they could not do anything with it and,

A friend of mine pointed me to this site. What a heck..nothing to lose.
Well, to make a long story short, the software worked beautifully and I was able to recover
167 pictures in the matter of minutes. Thanks and my brother thanks too.
