Benchmarks

Overview

Below are some benchmarks comparing the RaSCSI running on different variants of Raspberry Pi's, along with the SCSI2SD version 5 and an original Apple hard drive as a comparison.

Test results

Overall Disk scores

Some notes on this:

• There are multiple SCSI2SD scores. I ran the test on two different volumes on the SCSI2SD and got slightly different scores.
• I suspect that the Pi 0 got higher scores because the RaSCSI software only uses one core. This gives the Pi 0 a slight clock speed advantage

Disk Read Scores

Disk Write scores
