Hello everyone.
The other day (12/2020), I benchmarked various manufacturers' SD memory cards on my Quadra700 (PPC50Mhz) and FWB JackHammerSCSI with SD2SCSI Version 6:2020. I would like to share the results here.
I hope this will be helpful for those who are planning to buy SD2SCSI.

SCSI:JackhummerSCSI
OS:8.1 Japanese

1) About SCSI2SD
First of all, there is a big difference between the latest V6 and the earlier versions.
V6: Maximum transfer rate 10MB/s
V5.5: Maximum transfer rate 1MB/s
V5.0,5.1: Maximum transfer rate 2.3MB/s~2.6MB/s
Therefore, if you are buying a new one, V6 is recommended.
Note: However, if you use the internal SCSI, the SCSI itself is slow.
Performance is the same for both V6 and V5.
We do not know why it is so slow.
Maybe it can be changed by adjusting the settings.
For more information
http://www.codesrc.com/mediawiki/index.php/SCSI2SD#Technical_Specifications
for more information.
2) Setup
First, you will need to set up the
http://www.codesrc.com/mediawiki/index.php/SCSI2SD#Download
to download the setup software.
If you are using V6, be sure to download the V6 software.
Download the latest firmware along with it.
Windows, OSX, etc. are supported.
Connect the PC and SCSI2SD via USB.
After downloading, run scsi2sd-util.
(I did this on a Macbook AIR M1)
After launching, the status will be displayed in the lower left corner of the window.
After launching, you will see the status in the bottom left corner of the window, and if it is connected,
it will show firmware version 6.3.1.
Let's upgrade the firmware to 6.3.2 first.
If the menu does not respond at this point, click on another application window, and then try again.
If the menu does not respond here, click on another application window and go back to SCSI2SD_util. It should work.
Select FILE>UPGREADFIRMWARE... and select the firmware you downloaded.
Select the firmware you downloaded and update it. It should finish soon.
Go back to the menu.
In the "General" tab, I set the following
SCSI Speed Sync, 10MB/s
Startup Delay(second) 0
SCSI Selection Delay 255
Enable Parity : ON
Enable Unit Attention : ON
Enable SCSI2 Mode : ON
Respond to short.... Map LUNS to SCSI...: OFF
Map LUNS to SCSI...: OFF
Enable Blind Writes : OFF
Device1" tab
SCSI : 0
Device : Hard Drive(Defaults)
SD card start sector : 0(Defaults)
AUTO : ON
Sector size : 512 (Defaults)
Device size 2GB
The following settings need to be changed when using APPLE standard formatting software.
I used a third party software.
I left it as it is. (HARD DISK TOOLS Kits, Lido, etc.)
Vendo codesrc(Defaults)
Product SCSI2SD(Defaults)
Revision 6.0(Defaults)
Serial number 1234567812345678(Defaults)
Set the "Device2" tab as well, if necessary.
Set the SD card start sector Auto to ON.
The sector count will be automatically set according to the capacity to be allocated.
I tried to set the Deice further, but
In my case, when I set it, the SCSI2SD stopped responding.
This was the same phenomenon even after changing the memory card.
I don't know the cause.
When you have finished setting up
FILE>SAVE to Device
and save the settings to the SCSI2SD.
This setting seems to be saved to the SD card. (I guess).
So, if you replace the SD card, you will need to configure it again.
At this point, the drive you have configured is automatically mounted on your PC.
Please unmount it and then unplug the USB cable.
3) Connecting to Macintosh
Connect the drive to the SCSI cable and turn on the switch.
The formatting and OS setup are omitted.
I used a floppy EMU
https://www.bigmessowires.com/shop/product/floppy-emu-model-c/
and formatted it with Lido 7.6.1.
4) Benchmark
The following is the data I measured with MacBench 3.0.
