I recognise installing an SATA/SSD is clearly less complicated than an NVMe PCIe blade. I have read the installation procedures and am not fazed with the task as I have previous experience upgrading G2 processor and graphics card, and installing optical and HDD in 24' iMacs. I am considering a speed upgrade converting my iMac 2019 5K to SSD and I seek advice regarding choice between NVMe/SSD and or replacement of internal SATA HDD with internal SATA/SSD. Upgrading Fusion Intel iMac : most cost effective use of SSD. But I am not ready to give up on upgrading this machine to SATA 2.0 and SSD’s.Could somebody please recommend a good PCI-X SATA 2.0 host controller (2 ports or more), that is stable, installs easily, and fully compatible with both Tiger 10.4.11 and Leopard 10.5.8? I do not even care if it is not an official Mac supported product, as long as it will recognize my SSD’s and give me the 3Gbps transfer rate, I’ll figure out the rest. Especially in the OS X section, there seems to be many errors.

Also, the instructions in the manual are generic and seem to be for multiple different devices, and not everything seems applicable. They did exist at one point.The manual is abysmal, and appears to be written by someone whose 1st language is probably not english. I don’t really care about the raid, just the upgraded SATA speed.I am pretty sure the issue is that the disc it came with does not have drivers that have a universal or power PC binary, and I cannot seem tofind ones anymore. It is a HighPoint RocketRaid 2210 PCI-X card that is SATA 2.0. PCI-X cards are not very prevalent, and I got one that appears to be compatible, but isn’t working.

I am aware of that the G5 only has SATA 1.0 onboard, and because it does not have PCI-e and takes DDR RAM, can only be upgraded to SATA 2.0. I have bought two 1TB SATA SSD’s for this machine after successfully upgrading both my late 2008 & mid 2012 MBP’s with HUGE boost in performance. I have a dual 2.0GHz, AGP, & PCI-X G5 (2004-2005 model).I have already upgraded it to 8 GB of RAM, replaced the video card with an ATI Radeon an Pro 9600 Mac/PC edition w/256 MB RAM, replaced the original superdrive with an 18x DVD-RW drive, and had a 500GB 7200 RPM SATA HDD, and another 320GB 7200 RPM SATA HDD.
