Gitratech only uses high quality NAND flash memory from Hynix, Samsung, Toshiba, Micron or Intel. When we fulfil your order we will choose the NAND memory brand which represents the best mix of performance and value at the time of fulfilment.

A guideline of our standard flash drive read/write speeds is as follows:

USB 2.0:
Sequential write speed range = 4~10 MB/s
Sequential read speed range = 15~25 MB/s

USB 3.0:
Sequential write speed range =10~20 MB/s
Sequential read speed range = 40~50 MB/s

These read and write speeds offer a guide to Flash Drive read/write performance and were determined in recent testing. Kindly note that we change USB Flash Drive components from time to time based on availability and cost. This means that the above read/write speeds cannot be guaranteed.
