You mean the Q version ?Sabrent Rocket v1 user here - amazing. Do not buy the new ones they cheaped out when they got popular on the nand.
Those ones are no good for sustained file copy but also I'm lead to believe the existing refreshes of the normal rocket are not what they used to be.
Well for that purpose it would still be perfect
I get 3440mb read but like I said they changed them to cheaper chips.
And if it's Rocket Q, that's step lower tech QLC Flash drive.
WD Blue SN550 is right now the best priced TLC drive.
