TeamGroup sent us their 128 GB T-Force Spark to take a look at. The T-Force Spark is a 128 GB USB 3.2 Gen 1 RGB USB Flash Drive with advertised read speeds of 180 MB/s and write speeds of 90 MB/s. We ran the T-Force Spark through our suite of storage benchmarks to see how it performed. But is an RGB flash drive just a gimmick? The answer may surprise you.
