Ever benched a PCIe 2.0 SSD in Single Lane?

Recommended Posts

Posted · Original PosterOP

Has anyone experimented with a single lane SSD?

 

I'm curious if I can get 100 MB / second read from one. Just think how many SSDs you could connect if single lane was fast enough.

 

I think all you have to do is tape off three of the lanes on the SSD. I'm thinking about trying this.

That's supposedly all you have to do. Though at the minimum, you just need to block the #PRSNT pins except for the one at the x1 lane (see https://en.wikipedia.org/wiki/PCI_Express#Pinout)

x1 PCIe 2.0 would still be 450 MB/s or so. However it is possible to find M.2-to-PCIe adapters for x1 slots that would work for this as well.

And that is PCI-e 2.0 x1 from chipset on ASUS P8Z68-V PRO 

got a total of 4 x Plextor M8PeG 1TB on it.

You guys are awesome! Thanks so much!

 

I found some technical details online. I might need to use a single lane PCIe gen 1, which would give me a peak throughput of 250 MB/s, I'd probably sustain 100 MB/s on that.

 

I really appreciate your responses. Especially kokosnh. Above and beyond.
