GEN3i Remote Recorded Data Storage Overview
Using GEN3i in remote mode allows for several storage options. While in remote control, Perception on the GEN3i Windows
®
PC is closed. As
a result all Solid State Drives (internal and removable) are not usable anymore.
Continuous streaming throughput is tested by using 48 hours of circular recordings at specified data rates.

Tested using circular recording for 48 hours. Test setup uses a Windows
®
7 PC with Intel i7 CPU and SSD with sustained write speeds
exceeding 250 MB/s.

Compression ratio is defined by the ADC channel width. For details, please refer to the "Streaming Compression Ratio" table (below).
Rate is valid before decompressing storage data to maintain backward PNRF compatibility.

7 PC with Intel i7 CPU and SSD with sustained write speeds
exceeding 700 MB/s and a 10 Gbit Ethernet link.
