Hi. I have a bunch of those 5.25" to 3.5" SATA SAS HDD Hard Drive Cage Adapter Tray Caddy Rack Bracket For 3x 5.25" CD ROM Slot Internal or External PC DIY-in Computer Cables & Connectors from Computer & Office on Aliexpress.com | Alibaba Group in my storage servers. They are cheap, they work and did I mentioned that they are cheap? Only problem is that if I have 3 of them on a case that is 15+ drives to manage cables for. I fixed power cables by making my own 5sata to custom plug from modular power supply (modular power supplies ftw!) but data cables are hard to mod. I am thinking about making custom, simple pcb with sata/sff-8087+power on one side and pcb mountable sata + power connectors (like this: SATA connector female 7P+15P 22Pin 15+7 SMT Connector socket 90 degree for SATA hard disk interface 22pin , PCB board -in Computer Cables & Connectors from Computer & Office on Aliexpress.com | Alibaba Group) Only issue I have is to find information do I need any chip to convert 8087 to 4 sata ? 8087 is 36 and sata data has 7 (36/4 = 9). Is this a straight connection of pins from 8087 to pins in sata data cable ? Or do I need something more ? Thank you and have a nice day.
