A new bootable low cost Hard Disk interface compatible with Atari ST family computers,
and tested on a 520ST TOS 1.04, 1040STFM TOS 1.04, 1040STE TOS 1.06, 1040STE TOS 1.62 and 1040STE with TOS 2.06; with ok results.
Results: The ACSI2STM works perfectly; such example loading the current Metal Slug port takes around 4 - 5 seconds (aprox. 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: MicroUSB port cannot be used, instead, now each hard disk unit is provided with its own soldered USB cable.
Proof of ownership, in case of need; there is no date, because is a continous manufacturing;
the picture illustrates these hard disk units, Fujinet devices and Amiga 500/500 Plus trapdoor memories:
Operation video,
A video from the user PSIQ, many thanks!
Writing and reading from the hard disk interface:
On the last video, a game running from hard disk is shown; with "/" key, a savestate is created. After successful hard disk file writing, the game is closed pressing "*" key, and the STE system returns to desktop. A copy of the generated GS00.TOS file is created, renaming it to GS01.TOS; finally the game is resumed loading the copy of the savestate, GS01.TOS . All these operations are performed correctly.
-------------------------------------------------------------------------------------------------
The bootable hard disk image (DOS & TOS compatible, readable on Windows), can be obtained from atari 8 bit chip ( name: DiskImgPP1 ), or ask when you buy;
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€ + tracked shipment (6.5€ for Spain or 10.5€ for Europe - America, EE.UU. ; Japan, Australia, Alaska, Asia and Canada 11.5€) (New Zealand users - 12.5€ tracked shipment).
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,

An update, about tested micro SD card brands and types:
-Micro SD cards that work ok:
Sandisk de 1 GB
Kingston 8 GB class 4
Kingston 4 GB class 4
Intenso 8 GB class 4
Intenso 16 GB class 6
Intenso 4 GB class 10
Intenso 8 GB class 10
Kingston 16 GB class 10
Sandisk 16 GB class 6
Kingston 1 GB (tested by Shaoth)
Kingston 2 GB (tested by Shaoth)
Philips 64 GB UHS-1 A1 V10 Micro SDXC (tested by Shaoth)
Sandisk Extreme Plus 64 GB UHS-3 Micro SDXC (tested by Shaoth)
Samsung Evo Plus 128 GB UHS-3 Micro SDXC (tested by Shaoth)
-Micro SD cards that do not work:
Cloudisk 512 MB
No brand 4 GB
MediaRange 8 GB class 10
Sandisk 32 GB class 10 UHS 1 (most probably any UHS 1 will fail, due to these reject to operate in 1 bit mode)
Briefly, Sandisk, Kingston and Intenso are the preferred ones
------------------------------------------------------------------------------------------------
Current performance of the PCB track impedance version (February 2022):
Days ago, I finished a research to improve the performance, using the same stable and highly compatible firmware.
A redesign of the PCB tracks, and using a minimalistic SD card reader, lets the device reach around 1 MB/s
Edit:
Your unit is shipped,
You have a message with tracking number and usage tutorial
