Question Samsung portable SSD T3 very slow!!!

[gabrieljoria]

Hi, I have some questions about this Samsung T3 ssd. So, it is very slow, like 35/40mb reading and around the same writing. Tested with Samsung magician and crystal disk and used the 3.1 gen2 usb, 3.0 and 2.0, with Gigabyte X470 Aorus ultra Gaming motherboard. The board has an usb Type-c port as well but I don’t have type-c to type-c cable to test it. All drivers installed. The format of the memory is mSata so I took it out and tested with a motherboard (Gigabyte GA-Z77-D3H)that has mSata connector apparently at 3gb/s!!! and the reading was 285 read and 265 write. Guess the speed would have been higher if the Msata connector was at 6gb/s speed. So, any ideas? Can the cable be the problem? Thanks. Samsung

Did you check it on the z77 board externally by an USB 3.0 port as well?

Is the BIOS up to date of the motherboard?

Firmware of the SSD is up to date?

Yes it could be the cable. The max speed is always determined by the speed of the slowest device in the chain.
