Thanks for the help! I'll check it out. My hope is to be able to patch overclocking support into the kernel, I'll see how it goes.

I recently got my hands on the SATA HAT, and I tried creating a software raid using two 2TB drives. However, I quickly ran into some issues with the mdadm command on Linux. The issue comes when I try to create the raid device: sudo mdadm --create --verbose /dev/md0 --level=0 --raid-devices=2 /dev/sd...

Hi Were wondering what is a safe temperature to run the NanoM4 @ for long periods of time? With the large heatsink, running CPU at 100% for many hours, it creeps up to 70 degrees without a fan. This seems high to us to run for long periods of time Whats the design temp? Thanks! David I'm not speaki...

3.5" HDD can have very different power requirements - and difference between HDD with 1 and 7 platters (and with 1 or 2 actuators, like some 14GB+) can be few times - so it's no general solution. http://wiki.friendlyarm.com/wiki/index.php/NanoPi_M4_SATA_HAT says exactly about 12V/4A and 5V/4A ...

I sent an email to the tech support, and got this answer: The SATA power connector can output 5V/4A and 12V/4A, and will not be overloaded in this range. With a typical hard drive requiring <1A during regular operations, this should be fine. There might be a problem with current draw during startup,...

From the spec page of the SATA hat, I read: (A 12V/2A power can drive one 3.5" hard disk or four 2.5" hard disks. To drive four 3.5" hard disks a 12V/5A power is needed) I'm planning to connect up to 4x 3.5" drives, and I'll use a separate PSU to deliver enough 12V. However, I ca...
