Samsung Pro 950 M.2 512GB - Short Impressions
So I got a unit of this for Christmas. I was impressed by
TechReport's Review and felt that my X99 mobo should take the full advantage of that. What I wanted to do with it was to dual boot Ubuntu 14.04 LTS for my computing tasks and Windows 8.1 for gaming. In my existing setup, I have 2x1TB Samsung 850 in RAID0. Although I felt it's possible just to clone my existing partitions from the raid array to the m.2, I decided to do a fresh install (and upgrade from a 6-year Windows 7 install to a Windows 8.1)
After backing up my existing data on the RAID0, the installation itself was pretty quick and painless. One funny thing I noticed in my BIOS settings was that if I set my PCIE x4 to M.2, instead of Auto, the M.2 will totally disappear from the boot menu. Only after setting it to auto it actually come up. I suppose upgrading the BIOS revision could possibly fix this, but I decided against it since I would have to redo all my OC settings again.
After that, I used gdisk to partition the m.2 manually, then proceeded to install Windows 8.1 first, then Ubuntu. Strangely enough, the Ubuntu install script didn't detect the Windows installation for some reason, although it's nothing that grub-update can't fix.
I then repartition the RAID0 disk to be my D:\ to store my games, and /home to store my work. Restored my backup to the RAID0 disk took almost 7 hours , since I have almost ~800GB worth of Games and ~600GB of other data (And also I assume this is because the Linux FUSE driver isn't the fastest in the world). After reinstalling drivers and the like, the whole process took me almost 10 hours.
I didn't time the booting time properly since I have the GRUB menu wait 10 seconds for a menu select, but it probably took 3-4 seconds from the Windows logo to the login screen. (and roughly the same time for my Ubuntu installation)
Some synthetic bench for the M.2 after my backup was restored (at 63% full out of 250GB, the other half is my Ubuntu install)
And the bench for my D:\ in the RAID0 partition (at 60% full out of 1.3TB, the rest would be /home for my Ubuntu install)
I haven't run any demanding games since I've been playing Trails in the Sky FC, but I imagine load times would roughly be the same, since they're still in the RAID0 partition. However, I tried to run Photoshop to crop the screenshots above and it fired up in 2 seconds flat (as opposed to 5 seconds when it was running from my RAID0)
The rest of my specs:
