Hello,

I've noticed a strange behaviour with Samba drives on a 10 GbE link. If I use a RAM drive (16 GB) and copy from my server (through a 10 GbE link) to the RAM Drive, w10 reports > 1100 MB/s copy speed which is what is expected (the server has a fast SSD array and is able to almost saturate the 10GbE link)

Now if I test the same network drive from CrystalDiskMark, I get "only" 650-850 MB/s in sequential reads. Sequential writes are Ok and reach 1225 MB/s. Antivirus is deactivated in both cases.

Any clue why there is such kind of read bottleneck introduced by CrystalDiskMark itself ?

Regards

CrystalDiskMark 6 uses 128KiB block for SEQ test. But, Windows's copy use 1MiB block size.

Please use latest version. CrystalDiskMark 7 uses 1MiB block for SEQ test.
