I've heard that cause for those slow boot times are "non-installation" of original Samsung drivers and use of Windows ones...

Other than the occasionally really slow boot my system boots in under 10sec usually on the 950 pro. I think the occasional slow boot times are windows verifying boot files whenever it detects stuff changed. (I have CSM off, full UEFI boot). not sure why an X99 board would boot so slow on it unless it's plugged into a PCIe slot and the bios has to show option rom or something and spend extra time detecting boot device as apposed to M.2 being built-in to Z97 and above.

Gawd, if anyone has tips I'm open to them. I am running Windows 10 Pro, full UEFI bios, ultra fast boot, installed as UEFI from a USB stick directly to the 950 Pro and it's plugged into the M2 slot. I initially installed the Samsung NVME drivers after Windows booted for the first time. I've disabled CSM to test, re-enabled it - still slow to boot. From what I've read I'm not the only one. M.2 disks are super slow to boot. But, like I said, if there are any suggestions I'll take them.

Edit: Windows boots in about 8 seconds. The bios ads around 20 seconds from the time I hit the power to seeing the Windows logo. I also have 32GB of memory, so maybe that adds time to the bios? However, I think Ultra Fast boot skips the memory verification, if I'm not mistaken. But, with my old 840 Pro on the same bios version I was logged into windows within around 12 seconds flat from hitting the power button. So it ain't the mobo or bios. It's the 950 itself. At least that's what I've surmised.

sounds more like BIOS is taking it's time detecting the NVMe drive for some reason.on my Z97 board I have fast boot enabled, boot device only, and in windows i have hibernation off (which turns off win10's fast boot feature which uses part of the hibernation file to load up a tad faster). I dunno, maybe some of the above is why I don't experience the issues or because Z97 and Z170 have built-in M.2 support in the chipset. X99 doesn't afaik, but bios' were updated to detect and boot NVMe's

Edit: could try updating your BIOS, but if it's an Asus board and they released a newer motherboard version then you're probably SoL since they have a bad habbit of not supporting/updating previous models well.

Edit2: also, regarding the occasional slow boots I experience - I see the windows logo but it doesn't move for about 30-60 seconds, however I see HDD led activity like windows is verifying all boot files (happens sometimes when I update drivers or change some service startup and such). otherwise i normally boot from bios to desktop in like 10 seconds

P.S. Still waiting on Samsung's promised firmware update... sigh.

I'm running an Asrock x99 Extreme4 with the latest 3.40 (as of tonight) bios with a 5820K. I see no reason for this thing to be slow. I've never had issues with Windows booting slowly, just the bios.

So I spent some time today to get Windows 7 on my PC again, originally I planned to use a secondary drive but I decided the 950 Pro was going to get it. One of my games doesn't cooperate well with Windows 10, so I figured I would jump through the double whammy of Z170 and NVMe.

I patched the .wim files for USB 3.0, and slipstreamed about 230 updates into my USB installer and the install was actually totally painless on my Gigabyte Z170X-UD3. I read about people making install partitions on the drives and all sorts of other things, but I just loaded the Samsung NVMe driver in a custom install and off I went with no problems. This drive feels massively more snappy on Windows 7 than it does on 10 for some reason and now the games are running good. I have a spare 240GB SSD with 10 still on it (I cloned that one to the 950 Pro when I got it) for games that need DX12.

NVMe is known to take longer to initialize than AHCI. You'll never get around it, nothing is wrong. This drive is MUCH faster at initializing than something like the Intel 750, so they have improved it somewhat. X99 in particular has a rough time with it. If you really hate it, get an SM951 AHCI version, same relative speed but no slow boot.

What is the latest firmware for the Samsung 950 Pro 512GB
post #1348 of 1916
Not sure why some BIOS are having long boot times. my avg bios time reported by windows is 8.5sec. I assume it's likely the X99 platform which released before NVMe/M.2 was natively integrated into the platform and PCH (it was kind of bolted on afterwards with duct tape)

Edit: Also I just tried my 950 Pro in a PCIe card adapter instead of M.2 slot, no difference in boot speed on Z97 but double the lanes at least (4x slot instead of Z97's 2x M.2,) though still PCIe 2.0 so it tops out around 1.6GB's but high IOPS.

I get about 40 seconds to boot from power button. Lots of time wasted outside of loading windows. I guess it is the 950 pro. Switched to the sandisk extreme pro to boot os since it is more ideal for disk setup with premier pro

Where do you see a reported boot time by Windows?
