I tried today to install and pic SATA drive which I did see in the ECS 2.2 Installer, but I ran into the issue with how Windows partitions the drives complaining about the end of the drive.
I have one test machine with a 1 TB drive. ECS 2.2b2 will install anywhere on the disk, BUT you must do the partitioning (including the windows partition) with miniLVM, LVM, or DFSEE (must be run under OS/2). Windows must not be allowed to to the partitioning, or it is not compatible with OS/2 (including ArcaOS). I am not sure, but you may also need to use AHCI. I didn't try it with the Dani driver.
What I did, when I replaced the 500 GB drive, was do backups of everything (including windows), put the new disk in, then I booted the eCS 2.2b2 DVD, and did the partitioning for all of it, with miniLVM. Then, I restored all of it, making sure that windows never touched the partitioning. That part can be tricky, because windows thinks it owns the world. The windows backup tool, that I used, was the Seagate Disk Wizard, which is actually a reduced function version of Acronis (which is the only windows backup program, that I know of, that does it properly). That program does require a Seagate drive (can be in a USB enclosure), but it is free. After that, eCS cooperated. Since then, I have installed ArcaOS a couple of times, with no troubles, that I didn't cause myself.
I will also note, that I put a 2 TB SATA drive into an older machine, that didn't have SATA support. I used a 4 Port PCI SATA RAID Controller Adapter Card (PCISATA4R1) which does not support AHCI. I still boot from an old 40 GB IDE disk, and I use the 2 TB disk to store my backups. it is effectively an OS/2 based NAS box, and it works very well with OS/2, windows (XP, 7 and 10), and I have used it with Linux Mint.
