    Windows 11 only has 45% of random write speed in Nvme SSD


    As you see above, the other performance is about the same, but in RND 4K Q32 T16 the speed has dropped significantly. I know that because the two software versions are different and the condition of the computer is different, it is normal for the performance to fluctuate, but this performance also dropped too much, and the performance remained stable low after many tests at different times.

  2. M2 NVME SSD

    I found this on a website called velocitymicro:

    "Modern motherboards use SATA III which maxes out at a throughput of 600MB/s (or 300MB/s for SATA II, in which case, it’s time to upgrade). Via that connection, most SSDs will provide Read/Write speeds in the neighborhood of 530/500 MB/s. For comparison, a
    7200 RPM SATA drive manages around 100MB/s depending on age, condition, and level of fragmentation. NVMe drives, on the other hand, provide write speeds as high as 3500MB/s. That’s 7x over SATA SSDs and as much as 35x over spinning HDDs!"

    Yeah, NVME SSD's offer greater file transport speeds. But other than that, what is the benefit of it for Windows with it having a direct connection to the CPU?

  4. Windows 11 only has 45% of random write speed in Nvme SSD

    NVME 1.3 Drive Bug

    Not sure which update exactly caused this issue to appear but my Adata SX 8200NP appears to have its write speeds capped at SATA speeds of 550MBps despite being an NVME 1.3 SSD managing NVME level sequential read speeds of 2.8GBps.
