I have an old HP Pavilion a1600n desktop computer with PCI-E x16 Version 1.0 slot in which I want to use Samsung 840 EVO SSD. My computer currently boots from Samsung 840 EVO SSD but only at about 120 MB/s speed as my motherboard supports Sata 1 only. I want the PCIe x8 or x4 card to make my SSD bootable when I attach it and if possible let it run at Sata 3 speeds. What speeds will I get roughly considering my PC has PCI-e x16 Version 1.0 slot? I looked at following on Amazon: https://www.amazon.com/OWC-Accelsior-PCIe-SATA-Adapter/... The problem is is doesn't seem to make SSD bootable. Do you know any such cards which are reasonably priced? Please let me know.
