    So ~3500MB/s is the limit of PCIe 3.0?

    PCIe 3 is around 1000MBs (it's slightly less but can't remember exactly) per lane. M.2 uses 4 lanes. But yeah, with overhead 3500 MB/s is around the max it would go to.

    I wonder if they are planning an EVO model eventually. The EVO prices are much more attractive than the Pro model prices.

    7W of power usage? That's on level of some 3,5" hdds.

    Yeah, good thing it's almost 45 times faster ;) Btw it's peak read/write usage and if you do that 24/7/365 that's like 12 bucks on your yearly energy bill.

    The Samsung 970 Evo in my MSI Tian laptop (PCIE 3.0) hits 3,500 and sometimes just a hair over that. This new one must be using a new controller too, because the PCIE 4.0 M.2 that I have (Sabrent Rocket) supposedly sits somewhere between (about 5,000). I haven't tested that yet as my next PC build is not complete. That one is Ryzen 9 3950x on an X570 motherboard with PCIE 4.

    Hopefully they built a new controller to improve random IO as well which nobody so far has improved upon with PCIe 4 drives.

    Give me 50% improvement on random io and just 2gb read writes in seq and they will have my money!

    got a MP600 in pcie 4.0 what's the point of those fake benchmarks ? where do you ever get 4000+ other than in benchmarking tools ?
    I've got one it copies files at like 1,6Gbyte/s guru3d review managed 2,17Gb but still far away from those totally fake numbers
    if you are on the market for a M.2 please don't use those numbers for your purchase decision they are meaningless

    edit just did a few copy tests (I only have one 4.0, all drives are M.2 Nvme on MSI Creator TRX40) :
    Corsair MP600 2TB -> Samsung 970evoplus 2TB : 1,6Gbyte/s
    Corsair MP600 2TB -> Samsung 970pro 1TB : 2,27Gbyte/s
    Samsung 970evoplus 2TB -> Corsair MP600 2TB : 1,85Gbyte/s
    Samsung 970pro 1TB -> Corsair MP600 2TB : 1,79Gbyte/s
    anyway as you can see 3000-4000 numbers are not only meaningless but in the end pcie 3.0 work as well if not better, the corsair gave me 4980/4273 "supposedly" in crystaldiskmark

    it's like the 300km/H gauge on sport's car... you may go fast but you never reach it...

    adding something if someone had a doubt, my M.2 are well cooled by the motherboard heatsinks and case fans
    M.2 #1 42 °C (MP600)
    M.2 #2 37 °C (970evoplus)
    M.2 #3 42 °C (970pro)

    This is the PCIe 4.0 SSD I have been waiting for. One of them anyways.

    So that makes the 970 Pro the final MLC consumer product from Samsung?

    i have achieved evo+ to evo+ copy around 2,2GB/s sustained on z390 platform, with you are little slower...

    I almost got a 970 Pro 512GB to replace my 950 Pro 512GB as my main drive.. Guess I'll wait a bit. Hoping the 512GB version is not too castrated compared to the 1TB version. And yeah hoping they improved random IO mostly.

    I am going to rock my Samsung 960 EVO 1TB for a while longer, When the next gen AMD CPUs arrive I will probably upgrade my whole system including whatever drive out there offers best performance, price and most importantly durability of Age + writes. (I read a few articles some years ago that NAND tends to die more to age, a worryingly small age at that, than actual writes. Is this still so?)

    Just for reference my current drive copying a 23GB mkv file from my RAM drive:

    1st 30% at about 1.8GB/s
    Remaining % slowed to about 1.1GB/s

    Visa versa (Read from 960 write to RAM drive):

    After V.small initial ramp up was steady at 1.42GB/s


    Yeah, that is certainly no 3.2GB/s read it is meant to be capable of, but then this is compressed data I guess (though I thought this drive was pretty good at handling this and applies more to writes anyway)

    Something must be wrong with your system, for example being PCI-e bandwidth chocked, because that's not how a 960 EVO behaves when it actually has all the 4 PCI-e lines available.
    I'm actually copying at 3.4 GB/s to a RAMDrive complete file beginning to end.

    And it writes at nearly 3 GB/s before the drop, which is indeed at around 0.9 in my case (using a 512 GB drive, not a 1TB one)

    I do have an AMD system with the 4 lanes straight to the CPU.

    Yup, something not right there. I can remember what it tested at when I 1st got it.

    Tested with CrystaDiskMark 5.2.2 when I 1st got it:

    Read 3325MB/s / Write 1956MB/s

    Tested CrystaDiskMark 5.2.2 just now:

    Read 3047MB/s / Write 1807MB/s

    Tried a bunch of large files with similar results. Will try re-installing the Samsung NVMe driver tomorrow and see if that helps.
    of course the drive is fuller now, 368GB free, but I would not expect that to have a significant effect.

    EDIT:
    RAMDrive with CrystaDiskMark 5.2.2 gets:

    Read 8195MB/s / Write 8033MB/s (1 CPU core, 2700X, maxed out must be a limitation of CrystaDiskMark 5.2.2 not expecting such fast drives)
