Here’s a table showing capacities from 1TB to 22TB and the corresponding available space considering binary units (1 TB = 1024 GB):

Capacity (TB) Available Space (TB)
1 0.91
2 1.82
3 2.73
4 3.64
5 4.55
6 5.46
7 6.37
8 7.28
9 8.19
10 9.10
11 10.01
12 10.92
13 11.83
14 12.74
15 13.65
16 14.56
17 15.47
18 16.38
19 17.29
20 18.20
21 19.11
22 20.02

Please note that the “Available Space” values are calculated using the binary definition of units, where 1 TB = 1024 GB. In practice, manufacturers often use decimal units, where 1 TB = 1000 GB, which can lead to some discrepancies in reported capacities.
