## Storage (Disk)

### Storage space
148151
Calculation formula: Number of measurement points * Sampling frequency (Hz) * Size of each data point (Byte, different data types may vary, see table below) * Storage time (seconds) * Number of copies (usually 1 copy for a single node and 2 copies for a cluster) ÷ Compression ratio (can be estimated at 5-10 times, but may be higher in actual situations)
