We carried on a USB 3.0 flash drive speed test and comparison and we now have 4 hot competitors at amazon.com from a couple of well-known USB brands – Kingston, SanDisk, HP and PNY.

4 USB 3.0 flash drives read and write speed comparison

Competition Rules:

A 10GB zip file will be copied to every USB 3.0 flash drive plugged in the same USB 3.0 port. And then this file will be transferred back from USB 3.0 flash drive to PC. We’ll analyze the reading and writing speed.

Our four competitors involving in this USB 3.0 flash drive speed comparison are:

No.1: Kingston 32GB DataTraveler Exodia USB 3.0 Flash Drive

No.2: PNY 32GB Turbo Attaché 4 USB 3.0 Flash Drive

No.3: HP 16GB USB 3.0 Rubber Ice Cream Flash Drive

No.4: SanDisk 32GB Ultra Flair USB 3.0 Flash Drive

Let’s see who’s faster.

And after intense competitor and speed comparison result, we will show you how to test speed of USB 3.0 flash drive.

No.1: Kingston 32GB DataTraveler Exodia USB 3.0 Flash Drive

Reading speed of Kingston 32GB DataTraveler Exodia USB 3.0 flash drive is not stable and wave a bit. But as you can see in the upper picture, it could hold at more than 155 MB/s at most time. And 155 MB/s is almost the lowest speed it could go. What I am trying to say is that even it’s not stable, its reading speed still amazed me. In fact, during the reading process, its peak reading speed is 243 MB/s.

Furthermore, its writing speed maintains at high level. It almost hangs on 38.4 MB/s which is pretty nice already.

No.2: PNY 32GB Turbo Attaché 4 USB 3.0 Flash Drive

Even though it could not beat the Kingston one in reading field, PNY 32GB Turbo Attaché 4 USB 3.0 flash drive still outstands because of its unparalleled writing speed – 56.4 MB/s. At its best, the writing speed can arrive at 58.5 MB/s. Isn’t it worth an award?

No.3: HP 16GB USB 3.0 Rubber Ice Cream Flash Drive

HP 16GB Rubber Ice Cream USB 3.0 flash drive has the fastest reading speed among these 4 USB flash drives – 197 MB/s. But, it’s pretty upsetting that its writing speed barely reach to 25.1 MB/s which is clearly showed in the figure.

No.4: SanDisk 32GB Ultra Flair USB 3.0 Flash Drive

Actually, SanDisk 32GB Ultra Flair USB 3.0 flash drive performed well at first while copying item to it. And the writing speed reached up to 58.3 MB/s once. However, after copying process was 10% completed, the writing speed steeply declined to about 20 MB/s.

On the converse, reading speed is stable. It never disappointed me by holding its reading speed at 142 MB/s.
