Has anyone tried the 25Mhz firmware? I really need feedback if i am going to improve this.

My SD adapter failed to init and my CF card worked the same transfer speeds as 7mhz.

I tried it, no difference for me. It works the same as the other one, but I never really had any speed issues.

I have done some more comparison tests.

Amiga 500 Rev6 1MB Chip
I used this image https://drive.google.com/file/d/1Lzhb5M ... sp=sharing
SD2IDE on 2GB SD card - class 4

Boot time exactly the same. approximately 15 seconds

SysInfo
Standard firmware - 2,259 - 2,437 - 2,042
Experimental firmware - 2,097 - 2,215 - 2,069

I did run series of test using this : http://aminet.net/package/disk/moni/DiskSpeed42

My testing show that there is not real differences, on this particular tests which I have done it would even suggest that experimental firmware is slower, but I bet if I run it several times averages would be the same.

Tried the 25MHz firmware along with the 534 timings version on an unbuffered and a buffered card. The IDE speed and boot time were the same as the original Rev2b firmware.

I'm firmly in the "don't have any problem with the 536 IDE speed" camp.

I've never seen IDE speed problems either. So unless i can reproduce somehow i've no way to fix it. And its not like i only have a handful of Amiga's I've tested this on 2 different A500s, a A2000 (although i did skip the 2b on this one) and a CDTV. All worked fine. :/

I don't think there is a speed problem. I think maybe its people testing on the A500 and assuming they should be getting 1MB/s or more (when not using an MMU).

I think it red herring.

If there are complaints those might only be from people who had extremely overblown expectations.
Realistically 030 cpu, 64mb fast ram + 2,5mb/s ide is what you ever need on Amiga 500.

That's right, it was about long booting time, amiga reads whole bitmap of the drive, so if Your drive is 8 or 16GB (yes, You can use large drives with KS 3.1.4) it will take ages to boot unless You make bigger block size as default..

Till now I have soldered 3 cards. All runs at 108Mhz main clock, and no ide problems (no ide buffers)
Im using firmware tf536r2_2020_04_22
Amiga 500+ soj-mod 2MB chip Kick 3.1
I tested few SD cards.
WB3.1, Load Module/scsi.device 46.0 (Don Adan from http://wt.exotica.org.uk/test.html),MMUlib

SD 64GB(samsung evo plus)
0 System partition 0,5GB SFS Block size 4096
1 soft 1,5GB SFS Block size 4096
2 soft 2GB SFS Block size 4096
3 Soft 53,5GB PFS3AIO Block size 4096

BOOT time-Power on (one reset for load moudle included) 34s
Keyboard Reset time 19s
Speed sysinfo 4.0 around 3.3MB/s for all partitions
-----------------------------------------------------------------------------
Without LoadModule scsi.device
Boot time-power on 22s

sysinfo 4.0 disk speed 2.9MB

On small cards or big ones( but with small partitions only) i had boot time under 15s (clean WB3.1 + MMUlib)

SD 128GB was not recognized In system (not visible)
