I'm not sure I've ever seen speeds like this without RAID being involved...

APPLE SSD SM0256G.

Is this a new interface to attain such sequential performance?

It's been known for quite a while, you must've missed it.

The rMBP's been using PCIe instead of SATA since late 2013.

Yes they run PCIe 3.0 4 lane with new Samsung SSDs for insane performance. The 2015 13" and 15" are both running the faster drives.

As an update, here's the info from System Report of the 2015 15" MacBook Pro:

Vendor:Apple
Product:SSD Controller
Physical Interconnect: PCI
Link Width:x4
Link Speed:8.0 GT/s
Description:AHCI Version 1.30 Supported

That's clearly quite the improvement since my 2014 5K iMac's SSD:

Vendor:Apple
Product:SSD Controller
Physical Interconnect: PCI
Link Width:x2
Link Speed:5.0 GT/s
Description:AHCI Version 1.00 Supported

Wow the 1TB model (I assume) really is something else....
Indeed it is. If it were in a working computer (mine was effectively DOA).

When I installed Windows 10 in bootcamp, I ran the bootcamp installer and it said I had to restart. I've done that before a dozen times and it takes a while to shut down and reboot. On this machine I literally turned my head to answer the phone, decided not to, and turned my head back and Windows was sitting there on the desktop. I thought it had failed to reboot, so I did it again and it rebooted so fast that it left my jaw on the floor. The time from clicking "Restart" to it sitting there on the desktop waiting for me was less than 10 seconds. I've used SSDs for a few years and I've never seen performance like that.

Crazy. What was DOA? Symptoms?

Locked up hard after a time machine restore, then wouldn't do internet recovery (failed multiple times), and now it won't turn on at all. They are sending a replacement.
Ouch. That stinks. My friend's new 15" MBP had some oddities, too. He got it, used it for about a day, rebooted it, entered his password (FileVault enabled), and then it went straight to a black screen with a white circle with the slash through it. He had to do an Internet recovery last night.

Very odd...
