    Phoronix: Samsung 950 PRO M.2 NVM Express SSD

    The latest piece of hardware I've been playing around with at Phoronix is Samsung's V-NAND SSD 950 PRO M.2 NVM Express SSD. Assuming you are running a modern Linux distribution, this M.2 PCI-E NVMe SSD can offer blazing fast performance.

    Samsung really needs to come out with the 1TB version. They've promised it for 2016h1. Heck, even OCZ has a 1TB M.2 SSD now.

      I have two of these in RAID 0, I can confirm intense fastness.

        I have this module as well. Incredibly fast. It will throttle if it gets hot.

              The link that is supposed to go to the workstation motherboard in the article goes to the multi-queue article.

                I have one of those and it is great. There is one drawback if you use it as your boot drive (this is the only storage device I have in my computer in my case, so little choice), grub cannot boot on it as it does not recognize NVMe drives. I lost half a day and a part of my sanity trying to debug the issue. In the end I used systemd-boot and it worked fine.

                  Can you tests pts/sqlite with and without write barrier enabled (fstab mount options/on by default)?

                    A lot of people recommend using pci-e m2 cards with cooling fins on this SSD because of the heat and the throttling that happens when it overheats under heavy load.
                    I don't know how big that problem is under normal conditions, but that is pretty much the only negative thing I've seen about this drive (except the price compared to non-NVMe M2 SSDs).
                    This is still the only semi-consumer M2 NVMe SSD on the market, even though it's been out for a while now (except the predecessor SM951 NVMe which is hard to find).
