2020’s Fastest Raspberry Pi 4 Storage SD / SSD Benchmarks

We’ve now received over 20,000 benchmarks at https://storage.jamesachambers.com/! These are submitted by regular people from all over the world.

In celebration of that milestone as well as the launch of the 8GB Raspberry Pi 4 take a closer look at which device you should choose for your Raspberry Pi 4 as determined by science and measurement!

Best Performing Devices

Solid State Drive (SSD)

The Samsung 970 Evo Plus is currently the king. It’s not cheap, but a lot of people have it with a total of 49 benchmarks so far!

Secure Digital (SD / MicroSD) Card

The SanDisk Extreme A2 is barely edging out the SanDisk Extreme A1 variant for the top spot. The difference is tiny though, so you should pick whichever one is cheaper at the moment.

Storage Adapter Performance Note

The type of USB adapter you use (if you aren’t using a SD card) can have a big effect on performance. I cover which adapters are good and which should be avoided more comprehensively in my Raspberry Pi 4 USB Booting Post.

The most popular one at time of writing is the StarTech USB 3.1 to 2.5″ SATA adapter.

Benchmarking Your Own Device

I highly recommend benchmarking your own storage device. To run the benchmark paste/type:

sudo curl https://raw.githubusercontent.com/TheRemote/PiBenchmarks/master/Storage.sh | sudo bash

The benchmark only takes a few minutes and will give you a lot of information about whether your Pi is performing well or not. Storage is definitely the biggest performance variation between otherwise identical Pi setups.

Compare your score with others at the full benchmark browsing site https://storage.jamesachambers.com/. Leave a comment letting us know how you did or if you need any help!
