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).
Sounds good, but it didn't identify my camera as a drive.
I use an Olympus C740UZ with an XD picture card, and Windows XP.
Windows reads the camera as removeable disk E: but ZA failed to pick it up.
I tried all the different processes suggested by ZA help, without success.
Shame, because all the other reviews suggest it's a nice little bit of software.
Try it anyway, you've got nothing to lose.
