Laptops with 2500 MBs NVMe SSDs (Ever?) Discussion

by jederman Jul 11, 2016 11:33AM PDT

Hello,

I've been researching installing an SSD on my current laptop, which has a nornal SATA III drive bay and a mini pci-express (v2) with four lanes. After spending about two days researching which would be better, I have come to an impass. Apparently, both have a maximum data rate of about 550 MBs; and I need to use at least a 256 GB drive to get this speed. Also, it appears that the mini pcie bus is full duplex while the sata bus is half duplex. Again, it's not clear whether there would be any performance advantage since msata drives still use the sata protocol.

So I was wondering, will laptops, note books etc., ever be manufactured to use the "full speed," 2500 MBs, of a real PCIE bus? If so, when can we expect to see a retail unit; and who will be most likely to offer it? My bet is on Samsung, since they manufacture everything they sell. I'm expecting Quanta to enter this market later on.

Also, what will the form factor be? I'm guessing NVMe; but for now I think investing in any exotic hardware will be folly, since I think even the manufacturers haven't really decided on this yet. For my part, I have a quad-core DELL; but it still takes to long to open files. I travel frequently; and I'd much prefer a 13" model with a 4k screen and Gorilla glass. I really don't want a touch screen; but I do want a glass cover since I always manage to break my displays when wiping off the finger prints. I can keep an external DL/Blue-ray DVD burner at home or in the bag for SW distribution.

Any knowledgable comments appreciated.

The media speed is a fraction of the interface speed which makes me worry you are looking for gains where they are not to be found.

My answer, given the media speed (what's on the other side of the bus) is simply no. Not for now. We'll have to wait a while for the next big change.

The time to open files here is very fast. But I didn't install Norton or any AV that scans files on open.
