Vinpower’s USB duplicators work perfectly with USB3.0 drives, providing exceptionally quick copy speeds

USB3.0 duplicator speeds

A common myth is that you need to use a USB3.0 duplicator in order to achieve the high-speed duplication writing capability offered by USB3.0 flash drives. In reality, the actual write speed of a USB3.0 drive is much lower than the theoretical write speed listed by the drive manufacturers. Because of this, Vinpower Digital USBShark or USBDupe Box Duplicator, can still copy USB3.0 drives at their real world true write speeds. That means Vinpower’s USB duplicators will copy existing USB3.0 drives up to their real-world maximum write speeds, so there’s no need to pay 3 times the cost for a USB duplicator with USB3.0 socket connections. This may seem farfetched, but I’ll explain why this is true.

The key lies in the actual read/write speed of the USB drives themselves. The below chart shows the typical read/write speeds when reading or writing sequentially on the drive:

USB 2.0:
• Sequential write speed range = 3~10 MB/s
• Sequential read speed range = 10~25 MB/s

USB 3.0:
• Sequential write speed range = 10~45 MB/s
• Sequential read speed range = 60~150 MB/s

To begin with, none of these numbers reflect the true read/write speed found in real world use, largely because the drives themselves do not read/write in a sequential order. In reality, USB2.0 and USB3.0 drives read/write onto random memory within the drive. This is done in order to not overburden memory cells by constantly reading and writing to the same cells over and over again. To spread out the usage of the memory cells, the controller on a flash drive will select random cells to store segments of data across all the memory available. Since most people typically store multiple small files rather than a few large ones, writing lots of small files takes notably longer than writing a few large ones. Placing data in random memory cells and needing to write multiple small files greatly slows down the USB3.0 write speed to a more reasonable 10 ~ 20MB/s.

Even though Vinpower’s USB duplicators use USB2.0 connections, the max rating for USB 2.0 is up to 480Mbps (60MB/s), which the USBShark and USBDupe Box duplicators both support Read/Write speeds of:

• Maximum Read Speed33 MB/Sec?2GB/Min
• Maximum Write Speed31 MB/Sec?2GB/Min

So, based on the math of the max read/write ratings for Vinpower’s USB duplicators and the real world max speed of a USB3.0 drive, (10 ~ 20 MB/s), it clearly shows that Vinpower’s USB duplicators can adequately handle USB3.0 read/write speeds without any slowdowns or drop off in time or performance. So when you’re looking for a USB duplicator and think you need to purchase a USB3.0 duplicator because you plan to copy USB3.0 drives, save your money and the headache by using a Vinpower USBShark or USBDupe Box duplicator instead.
