Benchmarks
Below are some benchmarks comparing the PiSCSI running on different variants of Raspberry Pi's, along with the SCSI2SD version 5 and an original Apple hard drive as a comparison.
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 PiSCSI software only uses one core. This gives the Pi 0 a slight clock speed advantage

erichelgeson ran SCSI2SD v6 on a PowerMac G3 with Norton version 5 and received a score of 247. This high score was probably influenced by a much faster computer than a Quadra 840av, which was used on the other tests. But, its also likely that the SCSI2SD v6 also has a lot better performance.
