Performance - Storage USB 3.2 Gen2 and NVMe M.2

USB 3.1 / 3.2 performance

You are looking at a Crucial X8 1TB USB 3.2 Gen2 flash drive with today's tested motherboard. It is one of the faster external storage units available on the market and makes USB 2.0 at 25~30 MB/sec look rather pale in comparison. That is the maximum performance for the USB stick right there.

• 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 it can transfer data at up to 5Gbps.
• USB 3.2 Gen 2: Previously known as USB 3.1, and then later as USB 3.1 Gen 2. It offers speeds at 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 currently test with a Crucial X8 1TB USB 3.2 Gen2 (10 Gbps) Flash drive.

NVMe M.2

And a quick run of a random M2 SSD (PCIe Gen 4.0), and yeah I do not think that SSD performance on B550 will be an issue alright.
