Considering how larger data size has become these days, So i upgraded my entire system so I can save time while copying data but ran into below probelm.


Can anyone make me understand?

*Scenario one*

Copying data from
Samsung T7 2TB ssd, Up to 1,050MB/s USB 3.2 Gen 2 (10Gbps) specs

connected onto a USB port 3.2 Gen 1 Type-A with speeds of @5Gbps only
or sometimes I connect the Samsung SSD t7 to a Type-C USB 3.2 Gen 2 * 1 @20 Gbps ports on my PC

copying data to

Gdrive with RAID 0 configuration, with speed of 550 R/W , connected by a USB 3.2 GEN 2 TYPE A @10Gbps

Ideally I should get around 400-500 Mbs or 5Gbps speed , but getting only 250MB/s max and it keeps moving between 50MB/s to 250 MB/s , copying time is much longer ( data that gets copied are RAW FILES FROM CANON R5/ R6 CAMERS + NIKON Z7 CAMERS & VIDEOS FILES FROM SONY & CANON CAMERS)


*Scenario two*

Source - Angelbird CF express & ScanDisk Cf express cards with R/W speed of 1700/850 Mb/s , connected to PC by a USB 3.2 GEN 2 TYPE C @20 Gbps port

copying to a

Samsung T7 2TB Up to 1,050MB/s USB 3.2 Gen 2 (10Gbps), connected to a PC by a USB 3.2 Gen 1 Type-A * 2 @5Gbps only

in the above situation, I should get a minimum of 500MB/s copy speed when connected to a gen 1type A port, but still gets only a 282Mb/s speed that to for les time and then it drops between 60- 215Mb/s

This happens when no work is going on in a machine WHCIH HAS CRAZY SPECS

AMD threadripper 3970x
Asus TRX40XE GAMING
COOLMASTER ML360R TR4
GSKILL TRIDENT 32GB * 3 RAM @ 3600MHZ

Also card readers used are latest in market

CFEXPRESS TYPE B AND SDXC UHS-II DUAL-SLOT CARD READER | USB 3.2 GEN 2 from pro grade

&

Angelbird USB-C 3.2 Gen 2
10 Gb/s

Wondering where is something going wrong?

Posted this on many forums, but no luck.

Cheers
Robin
