    Super fast ssd drive if connected properly to you computer

    Super fast ssd drive if connected properly to you computer
    This ssd is exactly what I wanted, Super quiet, Super fast as long as you have the right setup to connect this ssd to. So your computer Mac or windows must have thunderbolt connection. Next use only a thunderbolt cable or you will not get the speed you expect. Also do not use any usb hub to connect through as it will decrease the speed substantially . I own a Mac Studio M2 Max Ultra. It has TB4 built into the Mac, and I use a true thunderbolt cable not just a usb-c to usb-c cable.I included a screen shot to show you the speeds I get. I have 1.02 TB of files that I wanted to transfer onto this ssd but did not want to wait hours as with a regular ssd. Well long story short, it took only 17 min to transfer 1.02 TB. thats super fast. I will NOT be returning this ssd. In fact I may buy another one as it's a great drive quiet , fast and very convenient. 5 out of 5 stars for me bar none.
