That is simply not true: Memory: power of 2 (bytes) Network: power of 10 (bits/s)) Disk: power of 10 (bytes) CPU Frequency: power of 10 (cycles/s) SD/Flash/..: power of 10 (bytes) Bus speed: power of 10 Main memory is the odd one out. >Just last week I had to remind people that a 24-disk JBOD with 1TB disks >wouldn't provide 24TB of storage since disks show up as 931GB.
