PCIe or SATA III SSD?

No. Most motherboards have at least 4 SATA ports, many these days have up to 8. The PCIe drive will often disable 2 of those ports, no big deal you still will have between 2 and 6 depending on the board.

Rogue Leader, so meaning if i will be using an m.2 ssd for example will give me the benefit of the most fastest storage drive ever but at a cost of slowing down other pci-e devices such as graphics cards?

It won't slow down other PCIe devices, however it will take up PCIe lanes so depending on your motherboard chipset you may then not have enough lanes to add something like a Sound card or WiFi card. It honestly is a minor issue thats of almost no concern to most people.



In some cases, but usually its only the last 2 SATA ports, usually leaving at least 4 ports for the user to still have.

That depends on how many ports there are. This only has 4 sata ports. If I used an M.2 SSD, it would disable 2

Altho, I dont have anything that uses SATA. Besides the 250 GB I'm using now. And, I cant add a dvd, there are no bays on the case

Unless, it's external

I thot if the more lanes being utilized by a device will likely limit the performance of the other devices using the same lane so technically it will be slowing out other devices when using pci-e ssd's. Plus a side effect of disabling some storage ports. Therefore i conclude, sata ssd is much better in real world applications right?

so it isn't really for flexibility this pcie ssd is. It limits and disables features. Im definitely going for the sata type

No, that only happens with GPUs because they use PCIe lanes that are run by the CPU. THe M.2 ports run off the chipset, use them all, using more won't hurt or slow down anything.

PCIe SSDs are faster, no doubt, the issue is in real life you really do not see the difference clearly. In some situations you may, but at this point the price is so high its not going to change your life if you just go with a good regular SSD.

Thanks for all the ideas and knowledge. But i now see ssd with pci-e is more complicated than a regular plug and play satas sd. Im going now for sata
