Device capacity for SIRIS 4, 5, & 6
This article outlines precise data storage capacities of Datto's SIRIS 4, SIRIS 5, and SIRIS 6 hardware devices.
Environment 
Datto SIRIS
Description
The storage capacities documented for Datto SIRIS devices are typically rounded to the nearest terabyte and are therefore not exact. The actual data capacity may vary from this standard capacity figure, and different device models that show the same standard storage capacity, may actually be slightly different from one another in terms of capacity. While these differences are small and not considered critical for most applications, we have listed more precise figures below.
For reference:
- 1 terabyte = 1000 gigabytes
- 1 terabyte = 931.323 gibibytes
- 1 tebibyte = 1024 gibibytes
The following chart illustrates the actual data storage capacity in gibibytes (GiB) based on SIRIS model.
