USB 3.1 / 3.2 performance

You are looking at a USB 3.2 Gen2x2 flash drive tested with the current motherboard.

It is one of the fastest external storage units now available on the market, and its transfer rate of makes USB 2.0's transfer rate of 25-30 MB/sec appear insignificant in contrast. That is the very highest performance that the USB stick is capable of.

  • USB 3.2 Gen 1: originally known as USB 3.0, and previously renamed to USB 3.1 Gen 1. It’s the original USB 3.0 specification and can transfer data at up to 5Gbps.
  • USB 3.2 Gen 2: Previously known as USB 3.1, then later as USB 3.1 Gen 2. It offers speeds of up to 10Gbps.
  • USB 3.2 Gen 2x2: formally known as USB 3.2, it’s the newest and fastest spec, promising speeds at up to 20Gbps (by using two lanes of 10Gbps at once).

We test with a USB 3.2 Gen2x2 (20 Gbps) Flash drive.


USB 3.2 Gen2x2 (20 Gbps) did not kick in properly for two tested devices we threw at it.

NVMe M.2 SSD Performance

CrystalDiskMark is a disk benchmark utility that measures performance for sequential and random reads/writes of various sizes for any storage device. It is useful for comparing the speed of both portable and local storage devices. CrystalDiskMark can measure sequential reads/writes speed, measure random 512 KB, 4 KB, 4 KB (Queue Depth = 32) reads/writes speed, has support for different types of test data (Random, 0 Fill, 1 Fill), includes basic theme support and has multilingual support. Give it a try yourself as it is free to download. The SSD is showing some very decent results back at us. Just compare read/write performance of the other drives shown.


Above: Silicon Power XPOWER XS70 (an SSD that performs in the 6000/7000 MB/sec range).
