PCIe SSDs slowly replacing SATA3 SSD
You know it, in my reviews I have been complaining for a year or so now that the developments for the SATA interface are not progressing. Most SATA3 SSDs these days are limited by the more narrow bandwidth the interface offers. As a result, we've seen SSD NAND storage in the form of M.2. on the rise for a year or two already.
M.2. is making use of the PCIe interface, often using a 2x or 4x PCIe 3.0 lanes ensuring you can even reach the 1 to 3 GB/sec marker compared to the ~560 MB/sec marker SATA3 offers. Sales are now reflecting this dynamic, there is a sharp move towards PCIe based NAND storage. There's another factor involved, NAND is getting cheaper, making fast NVMe PCIe based storage more affordable. PCIe SSDs are expected to become the new mainstream by the end of 2019 with a market share of 50%. Apacer Technology president CK Chang said that with better performance, consumer PCIe SSDs will gradually replace SATA SSDs.
Market sources said that unit price for 512GB PCIe SSD has fallen by11% sequentially to US$55 in the first quarter of 2019, compared to a corresponding price drop of 9% for SATA SSD, with price gap between the two types of SSD continuing to narrow from 30% seen in 2018. The sources continued that current average unit price for 512GB SSDs has declined to the same level for 256 GB SSDs registered one year earlier, and larger price falls for SSDs ranging in capacity from 512GB to 1TB are expected in the remainder of 2019.

They just need to drop in price.
Rather have a few cables than pay 50 bucks extra for speeds youre not going to notice in normal day use.
This. For an average user, Nvme adds nothing of value + it costs more.
You will never see a similar performance gain as when you upgrade from HDD to SSD.

Don`t ruin implants in consumers` heads - true enthusiast should use only newest hardware.

Considering how old sata 3 is already, it's weird there's no sata 4. I guess nobody is developing one? Most people haven't got too many M.2 slots. PCIe addon cards with an M.2 slot or two of them must be numerous, though I never look at them.

The problem is that the add-on cards require PCIe bifurcation.
Not all intel boards support that, and some AMD boards do.
I'd like to see the M2 connector go vertical, rather than laying flat on the motherboard. It takes up so much space!!!
They should be inserted like Dimms really, space wise.
Sata is basically dead I think for now. They tried to double up the bandwidth with SATA-Express, which was just terrible in terms of connector size, and space taken on the mobo also.
U2 isn't much better.
We probably need a 4-in-1 cable that has one connector on the Mobo, and breaks out to four M2 connectors, or more.
We could also do with seeing some more M2 backplanes for PC's, stuff that either fits in the 3.5in bays, or 5.25in bays, or both.

I have an M2 for OS drive, it's nice.
One thing though, how do you migrate an M2 drive to another M2 drive when your old one is dying?

Apparently not

We've been told by people in the working group that SATA will not be developed further.

SAS 12 Gb/s has been a thing for years, can't they readily port this over to SATA?

M2 is nice to have but definitely not essential and day to day t's very hard to notice any difference compared to a normal SSD and for the average user, they will not notice any difference.
Unless we really start going the micro PC route for the majority of PCs sold where space is really at a premium, I can't see why manufactures would change from SSD to M2 until it's cheaper for them to do so and at the moment M2 are much more expensive than SSD

M.2 is just the form factor... it's NVMe you guys are talking about.
I think M.2 SATA makes the most sense right now.

My issue with NVMe ssd's is that with consumer cpu's that only have 16 pcie lanes, you use up 4 up those lanes on the NVMe, meaning your gpu will only be running with 8 pcie lanes. Now this might not make a huge difference performance wise with a single gpu, but it can still affect performance, especially at 4k, and i personally wouldn't ever sacrifice potential performance for slightly faster loading times.

That would be pretty dangerous. M.2 drives are long and have thin PCBs.
If anything, M.2 Slot itself may be rotated in way that M.2 PCB is angled by 90° from MB. (Like mentioned memory.)
That would be less risky in case that M.2 slot itself can be robust enough. And in space of one M.2 drive, one could then fit 4. (If CPU has sufficient free PCIe lanes. Which is why non-server/workstation users do not actually need such solution.)

Yesterday i cancelled my order of a 2 tb 660p from intel.
At first i got excited of how cheap it is but then i read how it's speed gets crippled once it gets half full. QLC is cheap for a reason.
