A new Hard Disk interface compatible with Atari ST family computers,
Results: The ACSI2STM works perfectly; loading the current Metal Slug port takes around 4 - 5 seconds (aprox. 1 MB/s ,
2022 firmware reaches 1 MB/s).
Tested against old SD cards, such 1 GB card; 4 GB SDHC and 8 GB SDHC. All these are detected and works correctly!
Update 17 May 2022
The usual problem with power sources is solved!
Solution: In order to use any power source micro USB port is not recommended be used,
instead, now each hard disk unit is now provided with its own soldered USB cable.
On the video, a game is executed from hard disk; a savestate of the game is created, followed by a copy of this savestate, and finally load this savestate copy and resuming the game.

Photographs of the hard disk interface, Prototype one, final version do not have flying wires
The hard disk image (DOS & TOS compatible, readable on Windows) I used:
http://atari.8bitchip.info/DiskImgPP1.html
You can use Win32DiskImager (Windows) in order to write it.
The ST / STE with a hard disk is another world!
Each unit is completely built and tested,
price is 36€ + shipment , with tracking number (6,5€ for Spain or 10,5€ for Europe - USA - America 10,5€ ; Canada, Japan, Asia, Alaska and Australia is 11,5€
12,5€ New Zealand and South Korea).
Lower cost and better SD card compatibility than any Satan disk, and much lower price than UltraSatan.
Its the Atari ST hard disk suitable for the masses,
Thanks to user Dreadnought:
If you have a very old TOS operating system, such 1.00 or 1.02; you will need to use this disk image, due to some incompatibilities with hard disk partitions on these ancient TOS versions:
