I used the latest firmware from Areca's site, and I have a 1880ix-12 with 4GB of cache. I am not sure about if I can release the one of the firmwares I was using to accomplish this, but If you PM Computurd, he should be able to get it for you. Honestly, we ought to just let Areca know that the solution is working, and they can get it releases in non-alpha form. I am not even sure if the firmware is required, the command might be enough.

As for your drive configuration, I have no idea what to tell you there. I would suspect that with 8 spinning disks, having them all spin up that fast would be a bad idea for your power supply, but there isn't a setting to change it for individual drive groups. I would try "spin 128 4" if the SSD's are the first drives. You could try "spin 128 16" and see if it works. If it doesn't, you can always go back to the default by typing "spin 1024 1", I think. The document I used to get the command is not very specific on how it works and it's uses.

Should the first param after spin still be 128 if I have mix of 4 SSDs (M4 w/009 fw) and 12 regular HD (of 2 different kinds)?

And 2nd param - should it be 16 in this case or smth else?

Happy New Year!
