Raspberry Pi microSD card performance comparison - 2018

Raspberry Pi microSD cards Noobs Samsung Kingston Toshiba Sony SanDisk SD SBC

Back in 2015, I wrote a popular post comparing the performance of a number of microSD cards when used with the Raspberry Pi. In the intervening three years, the marketplace hasn't changed a ton, but there have been two new revisions to the Raspberry Pi (the model 3 B and just-released model 3 B+). In that article, I stated:

One of the highest-impact upgrades you can perform to increase Raspberry Pi performance is to buy the fastest possible microSD card—especially for applications where you need to do a lot of random reads and writes.

Raspberry Pi 3 B+ Review and Performance Comparison

Three generations of Raspberry Pi - model 2 B, model 3 B, model 3 B+
Three generations of multi-core Pi: model 2 B, model 3 B, model 3 B+

Whether it's been a 6-node Raspberry Pi cluster running Drupal 8, or a distributed home temperature monitoring application, I use Raspberry Pis for a wide variety of fun projects. The Raspberry Pi model 3 B+ is the latest iteration of the 'top of the line' Pi, with all the bells and whistles, and it still comes in at just $35. This year's iteration improves the CPU frequency, wired LAN performance, and WiFi performance, among other smaller changes, and I ordered one and have taken it for a spin.

What follows are my benchmarks and impressions after a couple weeks poking and prodding the new model 3 B+.

Review: ODROID-C2, compared to Raspberry Pi 3 and Orange Pi Plus

tl;dr: The ODROID-C2 is a very solid competitor to the Raspberry Pi model 3 B, and is anywhere from 2-10x faster than the Pi 3, depending on the operation. The software and community support is nowhere near what you get with the Raspberry Pi, but it's the best I've seen of all the Raspberry Pi clones I've tried.

Review: Raspberry Pi model 3 B, with Benchmarks vs Pi 2

On Pi Day (3/14/16), I finally acquired a Raspberry Pi model 3 B from my local Micro Center (I had ordered one from Pimoroni on launch day, but it must be stuck in customs). After arriving home with it, I decided to start running it through its paces. Below is my review and extensive benchmarking of the Pi 3 (especially in comparison to the Pi 2).

Hardware changes

There are a few notable hardware changes on the Pi 3:

How to overclock the microSD card reader on a Raspberry Pi 3

Late last year, I published a blog post with comprehensive benchmarks of various microSD cards used with the internal Raspberry Pi 2 reader, based on the comprehensive (and always-up-to-date Raspberry Pi microSD card benchmark page I maintain for the Pi Dramble project). After publishing the blog post, a few different readers pointed me to some overclocking tweaks that could help boost the speeds further for UHS microSD cards, allowing large file I/O speed to double, and random I/O to get a solid boost as well.

Orange Pi Plus Setup, Benchmarks, and Initial Impressions

tl;dr: The Orange Pi Plus offers much better specs, and much better performance, than a similarly-priced Raspberry Pi. Unfortunately—and this is the case with most RPi competitors at this time—setup, hardware support, and the smaller repository of documentation and community knowledge narrow this board's appeal to enthusiasts willing to debug annoying setup and configuration issues on their own.

A few months ago, I bought an Orange Pi Plus from AliExpress. It's a single-board Linux computer very similar to the Raspberry Pi, with a few key differences:

Benchmarking Safari on the iPad

Since purchasing the iPad, I've constantly been amazed by how fast everything works—switching between large apps is no longer a game of roulette, and browsing the web is a breeze.

I ran some tests on Safari on my iPad, just to see how things compare to my MacBook Pro...

SunSpider Javascript Benchmark

Here's the screenshot from my iPad (14068.6ms):

And from my Mac (406.8ms):

Sunspider Results - Macbook Pro

The MacBook Pro (2.53 Ghz 15" with 4 GB of RAM) is about 34x faster than the iPad in raw JavaScript performance... not too surprising, but I'd guess this margin will be trimmed in the next five years, when everyone's carrying around a tablet :-)
