Hi All, Can anyone give me an explanation on why I am not getting the advertise Speed from a USB3 Samsung SSD T7? It is connected to a USB 10 Gbps C socket on my PC M/Board, I am running windows 11. I have a ROG Maximus X Hero M/Board. The CPU is Intel Core i7-8700K CPU @ 3.70GHz(Coffeelake). I have 32 GB of RAM memory Under the Device Manager in Windows 11 Under storage controller it has USB Attached SCSI (UAS Mass Storage Device. Under Universal Serial Bus Controller, it has ASMedia USB 3.1 Host Controller (Microsoft) My Question is: When I run CrystalDiskMark 8.0.4 (x64), I get Read Speeds of MB/s 1033.96 I get write Speeds of MB/s 932.45. I am Happy with that! That is roughly what the advertised speed is.
In the real world when I do a file copy, a 100 GB image file From a Samsung 970 evo NVMe drive To the Samsung T7 Drive My transfer speed is only 574 MB/s. I am not happy with that result! Could you please explain to me why there is a difference in speed ? Can this be fixed with a driver, ? Please see screen shot Test results?
P:S Does the above M/Board have all these requirements ( supports USB 3.2 Gen2, UASP mode ) ? I am not sure if this is relevant as I am hitting the target figures in CrystalDiskMark?
