Imation Pace 64gb usb 2.0 flash drive - write speed?

Question

Data processing

Imation Pace 64gb usb 2.0 flash drive - we have it on sale for $5. There is almost no difference in price with 32gb usb 3.0 flash drives, for example, PNY attache4 - which has a write speed of 3.0 20mb / s, 2.0 8.5mb / s.
I've looked all over the Internet looking for data on the Imation Pace 64gb write speed - there's nothing.
If the record is 5-8mb / s, then there is no point in buying. If 13-15mb/s - that will go.
Help me find data on write speed.
