How Refined Storage disks count

Refined Storage 2 disks count only the total amount, not the number of different items: a 1k disk holds 1,024 items whether they are one kind or a thousand. Item disks come in 1k, 4k, 16k and 64k (1,024 to 65,536 items), fluid disks in 64B to 4096B, measured in buckets. A Disk Drive takes 8 disks, and a storage block of the same size holds the same amount as its disk without needing a drive.
