My cousin's pc: Intel G620 CPU 2.6 GHz || 4GB RAM || Hitachi 1TB spinny disc || 120GB Samsung 840 series SSD || Mobo: Asus P8H61-MX
The SSD was installed recently but the mobo only has SATA II ports. We are considering trying out a PCI-e card that provides a SATA III port but there seems to be ambiguous or complicated (control stuff I don't understand) or negative commentary around plus a very wide range of price/options that all makes my head spin.
From here we find the slots available: https://www.asus.com/Motherboards/P8H61MX/#specifications
1 x PCIe 2.0 x16
1 x PCIe 2.0 x1
1 x PCIe 2.0 x4
There's already a GPU, sound card & a USB 3.0 card on board. My cousin doesn't game or listen to much music so the GPU or sound card could be removed to rely on the mobo.
Is there a recommended cheapish card around?? And which of these pci slots should/shouldn't it be installed in? (my understanding is that there's an incremental increase in speed with one of them but full -potential- 6GBs is only possible through one of them, is that right??
My cousin's pc is nicely zippy right now for their medium level usage, so the alternative would NOT be to upgrade mobo, chip etc; it would be to leave the machine as-is. But (!) they have an SSD and in my view, they ought to try for the optimum speed, if feasible.
