The performance roughly corresponds to that of a SATA SSD. The SATA drive has about 25-35% better performance on large sequential files and over 40% better performance on 4K random reads. It lags far behind when it comes to random writing in 4k, around 80MB/s on a SATA SSD versus 21 on this flash drive. It's really solid. on a series. For the price this is the best place. The only better drive would be the Samsung Extreme Pro USB 3.2, but you pay at least a third more for the same size. I'm not even sure how much better that would be, but probably not much faster. I'm thinking of getting one of these suction cups as I bought two for my twin nephew's birthday gifts :D
