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).
I am not tech savy at all...
which is how I somehow reformatted the disc in my digital camera on the last day of vacation,
and lost all my photos and videos.
I came across this download and gave it a try.
[...] I did have to refer back to the demo for guidance on selecting the right "physical device".
The selections it gave me were unrecognizable to me.
The demo helped me understand what I was looking for.
All pictures are recovered, and I am grateful!
The movies were recovered as pictures (large jpeg files).
I can't figure out how to convert them back to movies.
Regardless, I am thrilled to have my pictures back.
