[QUOTE="NightShade, post: 3233839, member: 29706"] This is true the bus speed between PCI and PCIe is VASTLY different. PCIe also has different revisions so the later the revision the faster it is. However I know of no PCI based SSD's and likely it would end up being bottlenecked by the bus to not slower than a standard SSD that connects to SATA. Very few things actually use PCI any more, mostly sound cards and modem's or an older Network Interface Card. Even then PCIe versions are generally available. The nice thing about PCIe is that even though a card may be an x16 length it will function even in an x1 slot. The first part of the card is power and the rest of it is data lanes. It will work at a reduced rate but still is better than nothing at all, you will even find some of the shorter slots are open so that a full length card can be inserted into it. And even a PCIe x1 slot is now faster than a full PCI slot. SATA vs PCIe is VASTLY different as well. The tests I posted earlier in the thread were done using the SATA bus on an x470 chipset board. Doing a slightly updated test on the same board with PCIe gives the following results.

[CENTER][ATTACH=full]136632[/ATTACH] [/CENTER] So will it be an increase, yes.
