PCIE, M2 or SATA

[Brad Feuerhelm]

Hey all
I'm considering upgrading my Samsung 840 SATA 240g.

My question is which interface is the best/fastest?

I have and M2 slot PCIE slot and 1 sata slot available.

I THINK if I were to guess it would be the PCIE but I really don't know.

A lot depends on which motherboard you have.

My mobo is a ASUS P8P67 LE. I only have one sata slot left so thinking more towards m2 or pci-e.

You do not have an m.2 port on that motherboard.
That board came out long before m.2 drives were a thing.

Oh cr** you're right I thought I did oh well I think that tells me I need to go the PCI-E slot it's faster I THINK?

there is two thing, try not to confuse. form factor and io type.

Form factor:
This is the physical appearance of the ssd.
most of the ssd nowadays, form factor comes in 2.5 inch drive (using sata ports) and m.2 connection (using m.2 slot)
pci-e are less common as it occupies pci-e slot, and many are just a raid card with m.2 or sata ports.

i/o type:
IO type is the electrical connection it use to communicate with chipset.
sata caps around 600 MBps, problem is that the ssd chip can transfer faster than sata specification, hence there is a bottleneck on the sata io. sata comes in both m2 and 2.5" form factor.
NVMe (non volatile memory express) is designed to use pci-e as the underlying transfer channel. is about 1~4Gb/sp base on your NVME version. this can be found on your mb manual. nvme uses m.2 form factor.

as you can see m.2 offer both flavours of connection( sata and nmve ) you need to see how m.2 is wired in your user manual.
some offer both, some only works with m.2 sata. and some will disable your existing pci-e lane/sata port once in-use.

speed wise, nvme are faster, and give you a cleaner build (no more sata cable, sata power cable) but are also more expensive.

p.s. you will need a pcie m.2 adapter to house m2 ssd on your asus p8p67, for 2.5" ssd just use sata cable.

For that system, don't bother.

You can't boot from it. It would merely be a secondary drive.
And for most purposes, the price differential is NOT worth the speed increase over a standard 2.5" SSD.

OK Thanks at least now I know, I'll just upgrade the SSD 2.5 that I boot from which is a 240 I plan on going to 500g very soon
