## Tests Conducted
* **dd** - the dd utility is utilized to test disk performance. Both write and read speeds are evaluated by writing to and reading from a test file. Disclaimer: read speeds may be heavily influenced by cache depending on configuration of the host.
* **dd** - the dd utility is utilized to test disk performance. Both write and read speeds are evaluated by writing to and reading from a test file. \*Disclaimer: read speeds may be heavily influenced by cache depending on configuration of the host.
* **iperf3** - the industry standard for testing download and upload speeds to various locations. This script utilizes iperf3 with 8 parallel threads and tests both download and upload speeds. If an iperf server is busy after 10 tries, the speed test for that location/direction is skipped.
