So where will ssds move from NVME?

Just wondering with all the NVME m.2 SSDs starting to reach 3k+ reads/writes, whats coming short term on the storage industry, are we moving on full PCIe ssds on the future or will we get 8x NVMEs? or any other format that its coming short term?
 
I think we will see slower QLC drives of larger size on the consumer side.
 
In the consumer space it's highly unlikely that you'll ever see 8x NVMe SSDs. PCIe 4.0 is right around the corner, and PCIe 5.0 is already nipping at its heels. I don't believe the m.2 interface can even physically accommodate the number of lanes 8x would require (even if they introduced a new keying and ditched SATA, etc. support). Also, I'm not sure how much sense it'd make for the SSD's PCIe interface to have twice the bandwidth of the DMI 3.0 interface (essentially PCIe 3.0 x4) Intel presently uses for the connection between the CPU and chipset.

Not that it really matters for almost all consumer-level usage, where SATA is just as good and cheaper.
 
Even x4 3.0 has tons of room on the latency/IOPs front, which quite frankly is where the real speed improvement is for anything besides bulk transfers of large files.

Could you imagine >1GB/s 4k random QD1? Mmmmmm yeah.
 
Optane Dimm is already happening.

For the average consumer Optane need some competition to drive prices down. Also the the limits of pcie3 x4 is only at sequential or very high qd. It is by no means the limiting factor at low qd and random r/w.

PCIe 4.0 will double the x4 speed.
 
With PCI-E 4.0 doubling the current max speeds and PCI-E 5.0 coming within a year or two after that we will haev the capability of 15.5GB/s sustained speeds on NVME 4x SSDs. That is plenty for the foreseeable future. As others have said, the places for improvements are random speeds, filesystem speeds, and DIMM slot style non-volatile memory (Optane or otherwise). That is where things will be improving in the future.
