Hey there, just came to share my experience with 256 nvme on a Gigabyte Z97 SOC FORCE.
On a side note, I bought a cheap ($6.85 shipped)
pcie adapter and it's just perfect. With the drive at €129, that was the cheapest significant upgrade I ever made.
I had W10/64 installed on a sata SSD, CSM on, MBR. Cloned the drive twice for safety : Windows Image and acronis 2016. Burnt 2 uefi boot cards (CF on USB3 reader) for these tools (from W10-th2 iso, not the original one). Samsung nvme driver in both of them, just in case. I had tested the drive before and I confirmed that the Windows driver does hinder performance.
In Bios, disabled csm, put boot mode to "w8" and secure boot on. The cheap adapter card lets the bios detect the drive as nvme and pick it for boot.
Windows install boots from CF UEFI. Starts copying files at CF speed. Select the Samsung driver and create a simple GPT volume from scratch. Will repartition later for multiboot and such. Then the magic begins... before I know it, the windows desktop appears and it's doing its update thingy, already whining about activation. new side note : I entered my old w8 upgrade key, all good. Check Samsung nvme driver still loaded.
Reboot on Acronis UEFI card. Restore in file mode -NOT FULL DISK, leave EFI partition alone ! Reboot on Windows install disk, go to command line and do the diskpart and bcdboot things to fix the c: drive letter and point to the efi partition. Done, I converted my old windows install to uefi, which was only needed for booting from nvme. They won.
The improvement in boot speed is noticeable (already was stupid fast anyway) but day to day operation is a lot smoother. After repartitioning and pointing my browsers profiles to the m2 drive, I can tell when firefox starts up with all its tabs and extensions loaded. I used to leave it opened at all times, not any more. A lot smoother. Windows operation feels somewhat better too. I did a HDsentinel read test. That was funny...
This drive is indeed hotter that the hard disks or even the MX100 but the case has good air flow. I make sure to close the side panel and check fan operation. So far, idle is at 32 (24 in the room) load at 40. 45 max in lifetime (24 hours) but I installed Windows with panel opened, hence no fan.
Conclusion, I'm a happy camper, that was a well spent €135. Only disappointment is that Samsung software doesn't like the drive, pretends it's OEM, which is weird since I bought it in a store. No firmware upgrades on such new tech is not good by my standards. But i expect this first large scale nvme drive to only be the first in a fast growing series and soon be outperformed until those 4 pci lanes are the bottleneck. Then what ? a X16 lanes adapter for $ 6.85 ?
Me liky cheap upgrades: strong the cheap (and force) factor was with this one.Edited by archiesongs - 5/14/16 at 5:28am
