I have 6 HDD's in my build. 6 sata ports on my mini-itx motherboard.

 

This is my build from 2014: https://pcpartpicker.com/list/QX2Xk6  Just wondering if there's a better way. Currently I'm using this for 6 HDD's. Two of the sleeved silverstone cables and one sata power splitter. 

 

 

 

Actually I may just try 2 of these: https://www.amazon.com/dp/B01N6G22IU?ref=ppx_yo2ov_dt_b_fed_asin_title

SATA to SATA splitters are not good, to say the least. Practically anything is better, assuming it's compatible with your PSU.

 

My ideal solution without making custom cables would be to source 4 pin "molex" cables that are compatible with the PSU, then using as few splitters as possible convert them to SATA power.

 

If the PSU has 3 connectors for hard drive power, then 1 molex from each cable split into 2 SATA using a high quality crimped (not molded) splitter should work well. If you are short on space you could cut off the extra cable after the one molex connector on each cable that you are actually using. Obviously don't do that until you verify that you have the correct cables.

 

WHATEVER you end up doing, your first priority BEFORE plugging in any drives is to verify the voltage levels are correct at the SATA power connectors. You are playing a high stakes game of russian roulette with very poor odds if you power it up first time with your drives connected.

 

There are many posts here on this forum, and countless posts elsewhere on the internet about people frying their drives by using cables that physically fit, and were described as compatible. DON'T be another casualty.
