RN52x RN62x additional sata power
guys i need some brainstorming here for a very janky project of mine đ
i am planning to extend my rn526 and rn628 with additional disks using the internal pcie slot and additional sata adapter (not using RNOS).
additional sata data ports are not an issue, but i have no way of easily powering additional drives.
the powersupply does not provide any power cables other than those for the mainboard.
do you have any idea how to easily get additional sata power?

You can use a SATA "Y" splitter. One end connects to the existing power connector and then splits into two. They are all over eBay and Amazon. I have no recommendations.
Whether or not your power supply is capable of powering the extra drives, or you can successfully integrate them, I'll leave to the experts here.
unfortunately this wont work.
the nas doesnt have any sata power connectors other than the backplane itself, which is powered through the mainboard (no cables).
if i were to use y-cables it would make the backplane unusable.
The wattage of the power supply is also not up to the task of powering more drives.
And even if you do get it working using external power, the OS won't recognize the additional drives. The underlying Linux system will, but making them accessible is going to be a challenge.
What will work is to use a multi-drive USB chassis that has it's own built-in RAID. To the NAS, that RAID will look like one big drive. The only potential issue is that you likely won't find Linux-based tools for any special functions, especially not any that will work with Debian Jessie.
But in all honesty, your best solutions are an additional NAS or to switch to a 12-bay rack-mount NAS.
