The Samsung 950 Pro PCIe SSD Review (256GB and 512GB)
by Billy Tallis on October 22, 2015 10:55 AM ESTIdle Power Consumption
The idle power consumption I'm reporting here and in the Bench database is what's achievable on our 2015 testbed with PCIe ASPM disabled for the sake of system stability. Samsung's initial announcement of the 950 Pro specified an idle power consumption of 1.7W, which these drives manage to stay under. Samsung's later specs mention 70mW idle and 2.5mW DevSlp power draw. The former figure is something we hope to be able to verify in the future, but our power meter isn't sensitive enough for measuring DevSlp power.
As stated earlier, the power numbers for the PCIe drives are more of a worst-case scenario, due to our testbed being unable to enable their power saving modes. These active idle power levels have nevetheless been growing with each new PCIe drive from Samsung.
Trim Validation
Strictly speaking, NVMe doesn't have the TRIM command. The NVMe Deallocate command is the equivalent to the ATA Trim command, and since the trimcheck tool relies on the OS and filesystem to issue the command, it works without modification on NVMe drives.

Yeah, just buy Skylake motherboard, CPU and DDR4 RAM.And I'm not saying that it's simple, I'm saying that it's possible. You don't have to do anything special after setting it up, just keep small USB drive plugged in at the back of your PC.

Also, you can do it without additional USB drive, if you have at least one installed SATA device.Redstorm - Thursday, October 22, 2015 - link
Still a crap solutionEssence_of_War - Thursday, October 22, 2015 - link
I have had exactly two problems with GRUB.1) When windows destroys it because lolz.
2) When I was trying to install gentoo into a zfs root with on a luks encrypted disk.
Grub is fine and has been for a while.

windows shouldn't be able to mess with it if grub is installed on an external usb drive, and then setting the usb drive as the main boot device(all bios i've seen supports this). it's called chainloading, and it's not a bad hack if you don't have all the proper hardware but still want to try it. of course, it will require some technical knowledge. and because i'm poor, and can't afford a new system, if it works, it's good enough.hero4hire - Sunday, October 25, 2015 - link
If you're poor you wouldn't buy a nvme ssd. It is interesting to talk possibilities thoughEwitte12 - Saturday, October 24, 2015 - link
It didn't take much to figure out how to insert the nvme modules into a z87 motherboard. However I was prepared to replace it with a z97 if it messed up. I was NOT even considering the 600+ to go to skylake.Redstorm - Thursday, October 22, 2015 - link
Because what you propose is not a very good solution at all.eddieobscurant - Thursday, October 22, 2015 - link
The problem with that theoretical solution (which i've tried) is that windows won't let you install on it when it lists the disk drives.If you migrate an installation from a sata drive, you get a bsod upon restart due to the different ahci/nvme drive required similar to the ahci/ide for sata drives.
So there isn't a solution

You'd need to use the Windows deployment tools such as DISM to apply the WIM file, rather than run the regular install wizard.
