Second shipment was sadly a lot slower than the first shipment since it claims to be 3.0, I understand transferring big files slow it down but was having issues downloading 390MB 40 items and it showed it was gonna take 20 minutes, i had multiple usbs on so i tried it with just one, and for 11GB data it showed as an hour to transfer vs. another usb 3.0 i had it took about 10 minutes. First shipment was good, but the speed went down tremendously with the second batch. I would say if your looking for 1 batch go for it! But if your looking to get a shipment every 2 weeks and use it for mass data transfers this would not be a good idea. Great customer service, if you have anything other than a windows computer realize your other options for the H2 to test USB speeds. "NO NAME" is this usb in photos
