SSD on PCI-E or SATA III?

[skilltim]

For my next desktop build I am considering both interfaces. Is there much to be gained from using PCI-E over SATA III in gaming and general use? I want value for money but also great IOPS.

My thinking so far is this one: http/ocz.com/consumer/revodrive-3-x2-pcie-ssd
or this one: http/www.samsung.com/global/business/semiconductor/minisite/SSD/us/html/about/SSD840EVO.html

Any thoughts would be appreciated.

Hey there, skilltim!

To be honest, I don't think so. If you benchmark both in the 'perfect' environment, the PCI-e will give better results.
However, in real life both boot and program load times are not that different and you wouldn't notice much of it.
Especially for gaming, the SATA III SSD should be more than enough. Not to mention the lack of trim support in the PCI-e is also sort of discouraging (at least for me). On a gaming machine, I'd typically want to leave the x16/x8 slots for graphics cards, and use SATA III connections for the SSDs. You can't deny the speed of the PCI-e indeed, but I don't think it's going to make that much of a difference in your gaming rig.

Hope this helps.

well, you're comparing apples and pears. the samsung evo costs far less compared to the evo drive. let your budget decide, any ssd is much faster compared to standard mechanical drives and any pciex ssd is a bit faster compared to the sata 3 counterpart.
