Testing out twelve 9100 NVMe flash drives is not easy as it requires some interesting configurations to make the testing worth while, sticking them all in a box and running ATTO is not going to create valuable information. Those custom configurations revealed some interesting limitations, such as Windows' RAID having an upper limit of 385K IOPS and the Linux flavours tested topped out at 400K IOPS.
Server 2016 Technical Preview 5 turned out to be more stable than Server 2012 R2; somehow using Resource Monitor managed to crash hard enough to break the Server install in one case. 2016 also had that upper IOPS limit which was far below the drives actual capabilities. Drop by The Inquirer for look at the work which was done to set up for testing as well as the results.
"I have spent the past TWO months testing these cards, the past month of which has involved truly tormenting them. I've learned a lot of things. There's the basic "NVMe is faster" that you can get from reading about the theory behind the drives, but there have also been a lot of little practical tidbits that you only get to find out when you run face first into problems."

Can one use an nvme drive on
Can one use an nvme drive on any system? I was wondering if I could use one on an old i7-920 system with a pci-e adapter. I guess I wouldn’t be able to boot from it, but I could still use it, right? I have been experimenting with some VirtualBox VMs, but if anything is running in the VM it takes a really long time to suspend and restore the machine state from a hard drive.
Yes, you can use an NVMe
Yes, you can use an NVMe drive on an older X58 platform system, but yeah, you will not be able to boot from it directly. You can use it as a data drive (or even an OS drive with GRUB on another drive) though.
Yes NVMe works on X58. But
Yes NVMe works on X58. But understand this. It will choke itself to death sometimes because of PCIe 2.0 (tested). Basically you wasting 50% of available bandwidth on reads. I found out it’s more prudent to use multi SSD RAID setup (like 12-16 120 GB i535) which will max out at about 1300 MB/s with redundancy than getting single NVMe without it and which is pretty much wasted for reads big time. Talking serious work on X58.
