I have revision b and wonder if there was speed improvement in revision c or should both had the same speed?
Speed of BlueSCSI 1.0 b
- Thread starter slomacuser
- Start date
Revision C was mostly to facilitate using it on Mac that don't provide termpower (a B can be easily converted to C).
IMHO, the speed increase, if possible, could come by a optimisation in the firmware, but I think the software is stable since long ago.

Ok, thanks for answer. I have updated the drivers with Disk Drive Setup 1999-2000. Will try to reformat the card with exFAT so will have to use Windows not Mac to write the disc images on..
If you'd like to "upgrade" your b to c you can follow these instructions - as @pfuentes69 said it's just to allow proper termination in all power scenarios. Also if you bought from a reseller we did the bodge for you after we realized the issue. Hardware revs likely will not change any performance. OS 8 disk drivers (even if you're on an older system) will give you a few % boost. Still trying to get time to finish my utility to do that 
Well, I will leave it as is. Formatting it to exFAT made a 100% increase in speed! 
Testing with Norton System info the drive made a score of 55 (Just a little above Mac SE and below LC II), updating drivers made it a little above 60. Formatting the card made it 125 just above Quadra 700, 950, PowerBook 5300 and Duo 2300 which got 113 ...

Yep! That's why it's the first line on our Usage page

One more question. I can not use any system software above 7.5? System 7.1 and 7.5 work fine. System 7.6 or 8 do not. They lock just before loading desktop and alert box about wrong time clock.. any idea?
I had success with 7.6.1, but not when trying 8.x. I think later Eric made a better image to run 8, but didn’t try yet.
What machine are you using? I think 7.6.1 needs a 32bit clean rom, but not 100% sure
Me too... and 7.6.1 runs fine there. I have an image with 7.5.5 and 7.6.1
You can try it: https://www.dropbox.com/s/ttuuftaq93u9jq9/HD10_512_Sys755_500MB.hda.dsk.zip?dl=0
Just remove the .dsk in the name
It should start with 7.6.1 and you have System Picker to change to 7.5.5, but you could need to disable some extensions that I use in 7.5.5
thanksIn the LOG.txt what version does it say? If you are on the 20210403 you may need to upgrade to to 20210410 to have stable performance on faster machines. To flash you need an STLlinkV2 clone (real STLinks dont work well) and flash the new bin file. https://github.com/erichelgeson/BlueSCSI/wiki/Flashing#using-stlink-v2-preferred
