    I have an Eluktronics/Clevo N850HK1 with a 256G Samsung PM961 NVMe OEM drive. I am looking to replace it with a Crucial P1 1TB NVMe drive for more space. Because the PCI interface was an option on this laptop(SSD is stock), Crucial was unsure if this drive would work or not. The specs match up but I want to see if anyone here can provide a bit more information.
    The Crucial P1 is not the fastest or most durable SSD, but a Samsung 1TB drive is nearly twice the price.

    If you need consistency in 4k and seq speeds for longest duration go for SATA M.2 MX500 since NVMe gets too hot and throttle to SATA speeds unless properly cooled.

    Usually throttle is still 3x sata speeds and happens after you have continuously transferred 3x the drive capacity :p

    Crucial P1 QLC has small SLC cache, if OP was looking at ADATA SX8200/SX8200Pro with dynamic SLC cache which is very good.

    Well that's not throttling then, that's just the sustained transfer speed of the flash.

    I will only be editing 1920x1080. There is an SATA port, but there is a 1TB Crucial MX500 SSD there. Is overheating a common problem with NVMe drives? I've never noticed overheating with the Samsung SSD that's in the computer.

    I'm not expecting blazing speed at this price, so you think the ADATA SX8200 would be a better choice than the Crucial P1? I have not been keeping up with the latest NVMe SSD technology, I will check it out.

    Thanks for the info, I appreciate it.

    Crucial P1 has slow writes just like TLC based SSD w/o big SLC cache. If you're in the market for more space at half price of TLC P1 is a very good drive with max writes of 1GB/s. XPG SX8200 or Pro has 3.4GB/s read and 1.6GB-2.7GB/s with aggressive SLC caching to maintain sustained R/W speeds for about 150-175GB of incoming/outgoing data.
    Whichever NVMe drive you choose they heat up pretty quick. You can use a M.2 SSD Heatsink to reduce the heat and avoid slow writes due to high temps.

    The p1 can sustain 1.8GB/sec for 60 seconds and recovers quickly so unless you are transferring over 108GB files consistently then you will be good.

    Read speeds, correct?
    If you already use MX500 then P1 will be your natural choice. P1 and ADATA XPG SX8200Pro use the same internal flash memory so endurance wise you're pretty much covered. If you are using the SSD heavily I'd recommend ADATA XPG SX8200Pro or BPX Pro for better endurance and value for money.
    You've 3-4 choices now:
    Better than 970 EVO and a little notch above/below depending on benchmarks: High Endurance at best value
    ------------------------------------
    SX8200 pro
    WD Black 2018
    MydigitalSSD BPX Pro
    ------------------------------------
    Crucial P1 ->Crucial's first QLC device in the market after Samsung and intel released their QLC lineups. Has 5 year warranty, benchmarks are slow, suitable for most workloads and general usage.
    If your workloads are write oriented, then the SSDs in a dotted line should fit the bill. For general usage, you won't even feel a difference.
    Boot speed is slower on NVMe than SATA. NVMe takes a small time to initialise.

    No 108G file transfers, not even close. Most files are only a couple hundred MBs.

    Lots of helpful info there. Thanks.
