I've asked Netgear to update their Raid Calculator with newer disk sizes. Until they do... enjoy mine

This tool calculates drive utilization via RAID formulas. In standard and traditional RAID,
using a mix of drive sizes can result in unused space. NETGEAR ReadyNAS feature X-RAID®,
a technology which automatically utilizes all unused space which can be made
redundant regardless to the mix of drives used. NETGEAR Flex-RAID® offers a variaty of expansion options, including the ability to create an encrypted volume.
This tool is not a volume space simulator, so it will not calculate expansions. This tool assumes a factory defaulted state for each drive configuration.
Compare the results in the top RAID calculations with the bottom RAID calculations, to see the benefit of one configuration to another.
The RAID Calculator will give you an estimate of how drives will be utilized in different RAID
levels, actual utilization may vary. This calculator only gives an approximation, it accounts for
raid overhead and also the OS and swap partitions, however it does not
account
for filesystem overhead or snapshots.
With Flex-RAID® RAID 10 it is best to have an even number of drives.
X-RAID® dynamically changes raid RAID1 for 1 - 2 drives. RAID5 for 3 - 6 drives. RAID6 for 7+ drives. FLEX-RAID® maintains the RAID type.
The ReadyNAS OS6 supports Flex-RAID® RAID 50 and RAID 60. However, this calculator doesn't support those calculations.
Not enough hard drives for your selected RAID level. Please add
more drives or change the RAID level. If using RAID10 make sure to have an even number of drives.
