SSDs are obsolete
-
They offer many advantages over disk drives, which will also continue to sell in the hundreds of millions for years to come, but the motivating idea behind SSDs - fill those SATA ports! - is less and less relevant to today's systems.

I'm not sure if I completely agree with this.

I totally agree with Robin here. But you have to take his meaning.... SSDs using the same architecture as old, slow spindle drives ARE obsolete, because it is an expensive and unproductive use of SSD technology. SSDs attached directly to the PCIe are not obsolete and something akin to that will be the future of flash storage - faster, cheaper and more reliable. The whole drive bay and form factor exist for spindles, not memory.

How do you plan on fitting that many PCIE ports in a computer? I have around 20 SATA/SAS ports in my desktop plus a 4 port PCIE expansion. I'm using all expect three of those ports in my system. There's no way I would have the same flexibility without using some sort of harddrive bus.

That's the point that a new connection technology is needed to make it more useful. However, you have so many SATA/SAS ports because you are not using PCIe. A single PCIe port can handle the throughput of all of those combined AND the drives can be larger. So the needs are different.

I can't fathom how the system would be different, though I'm sure to the end user it probably wouldn't be that much different, to use RAM like storage with SSDs instead of drive like storage.

To the end user a computer is always a computer. It makes no difference how it is done. But to IT it means lower cost, higher density, better reliability.

damn click bait title for the article
better title would be "I think we should do X because Y"

I think there may be a change of interface however I don't think putting them directly on the motherboard is a good solution for anything besides laptops/portables. and low end desktops.

Very much so. The idea that SSDs are obsolete is based on the misapplication of the term SSD to refer only to SSDs that physically look like spindle HDs.

Why not?

Not very flexible. That's a major step backwards.

How so? What flexibility do you lose?

Do you mean soldering them into the motherboard? Or you don't think having them communicate over the PCIe (or replacement) connections is a good idea?

I see no problem with using the PCiE bus as long as you put it in a cable form. Putting them directly on the motherboard is very limiting as far as customization whether soldered or not.

PCIe cables already exist.
But putting them directly on the motherboard is little different than drives in servers today. That's how they work with their backplanes.

I'm not sure I agree with that. (The solder thing totally) How is this any different then current backplanes for SAS or SATA?

Yeah I have one PciE cable.
but It was like $200 -

Space. If it's a daughter card with access that would be fine. But on the actual motherboard wouldn't be.

With the size of some of the PCIe SSDs out there I don't think space or accessibility will be an issue, at the server level probably but not at the workstation level, They are making some of those SSDs half height cards now. Wasn't there a post about the new PCIe spec having cables which are keyed for different uses?
