Nowadays, solid-state drives have basically become popular, and a laptop without an SSD is embarrassed to be sold in the market, but for PCs 20 years ago, it is a luxury that cannot be climbed. However, a few days ago, the folk god Pierre Dandumont took the initiative to successfully install an M.2 SSD on a PowerMac G4 computer released by Apple in 1999.
It's not complicated to say, Dandumont uses a PCI (non-PCIe) expansion card with a Samsung SM951 SSD. Not all SSDs will work, the M.2 SATA will, but the M.2 NVMe model must choose a model that supports AHCI.
To successfully start running the SSD, you also need a specific version of the Mac OS X system and a compiled BIOS, and the final measured speed is 133MB/s.
Since the Power Mac G4 is only equipped with a USB 1.1 interface, the speed is up to 1.5MB/s, even the faster FireWire 400, it is only 50MB/s, so the addition of M.2 is not a negative optimization.
