What type of connector is it? You just plug it into the U.2 socket? Would the cable fit under a GPU card (is it stiff)?
The U.2 format is for use in drive bays. Instead of a SAS or SATA cable it's a U.2. U.2 is really just a PCIe lane extender.

There are so many hard-drive sockets, and no consumer board have 6-8 sockets like we have in SATA3. So we aren't about to build a RAIDZ2 at home soon with these drives.

I was at the same time wondering how it compares to (e.g.) a Samsung 960 Pro, not only wrt performance. Here are some numbers:
Optane 900p 280GB
5.11 PB and a MTBF of 1.6 million hours
Power: 5 Watts idle, 14 Watts load.
5 year warranty
960Pro 512GB
0.4 PB, and a MTBF of 1.5 million hours
Power: 0.1 Watts (idle), 5 Watts (load)
5 year warranty
So, in summary: more endurance (10x), but more power consumption (10x on average, depending on load). Perhaps not yet ideal for a laptop? Am I reading this right?
And yeah, I don't find this expensive, not with that performance.

This is something I also don't get. No offence but the Samsung drives Michael uses in the tests are already two years old. I've had 960 EVO for almost a year now.. Of course a new drive seems fast compared to legacy hardware. Even Core i3 is fast compared to Commodore 64..Michael Larabel

I was going to budget for 64-128 GiB of RAM for my next build, but I think I'll do 32-64 GiB plus an Optane swap disk-- would cost less than a lot of the 128 GiB RAM kits out there and would probably be fast enough. This is a big statement coming from me, since I haven't used swap since about 2009, but it looks like the economics of storage vs RAM have made swap worth using again.
Michael-- would appreciate benchmarks comparing a large-memory configuration vs. Optane swap, if you have any suitable memory performance benchmarks in PTS.
