![]() Yeah-yeah, so you would just pull it out without the "Safely Remove hardware and Eject media" Main issue is in that that Windows (oh wily) turn all these benefits by default in favor to non-safe device ejecting so you would just pull it out and forget about it :) You have just plugged-in your external SSD and started copying files from/to your PC/laptop and enjoying of the process thinking that 50MBytes per second is the maximum of all of that?īut just do a simple calculations in your head or just think/google about that USB 3.0-3.2 and SSD - supports more than 500 MBytes per second or 10 times faster or should take 6 minutes instead of 1 hour (60 min)? Hopefully, at some point, we’ll find a USB flash drive that offers both affordability and performance for the Pi, but right now, we don’t think any exists.You have just bought a leptop or PC that supports USB 3.0-3.2 (blue color of USB ) and an External Drive case with USB 3.0-3.2 for your external SSD and decided that you would taste the speed, power and all other benefits of the latest technologies? So, for now, my advice is to get an external SSD for your Raspberry Pi only if you are planning to use it as a file or web server and you can afford the premium. We’d like to see an affordable Flash drive that’s designed to work well on the Pi, but absent that, you’ll likely spend well over $100 purchasing both an M.2-to-USB 3.0 enclosure and the associated SSD. But, according to our tests, there are also a lot of scenarios, like streaming video, surfing the web or transcoding media, where having an SSD doesn’t help.Īnd, if you get a USB Flash Drive - unless it is one that has particularly high random read and random write numbers (two things not in a spec sheet) - you’ll actually have a far more sluggish computer than if you just stick with a plain old microSD card. The Bottom LineĪdding a powerful, external SSD to your Raspberry Pi 4 B can boost performance in certain areas, most notably application load times and web / file serving. There was no difference at all between the different storage types. LAME MP3 Encoding Test on Raspberry Pi 4 with and without SSDĮncoding MP3 files with LAME was a similar experience. The SSD was usually 2 to 4 times faster than a microSD card and as much as 13 times quicker when dealing with large, sequential reads or writes. IOzone’s synthetic results confirmed what we found through regular use. Blocks on the lower end of the spectrum, particularly during random reads and writes, represent the most common use case for opening and using apps, while the higher block sizes are good for saving or copying large files. We performed our tests using a 100MB storage file and found the most interesting results with the 4K, 512K, 1024K and 16,384K (highest) block sizes. The Linux equivalent of Crystal Disk Mark, IOzone, is a synthetic test that gives you sequential and random reads and writes. IOzone File Transfers: 2 to 4 Times the Speed Very often just opening the start menu was laggy, with submenus taking seconds to appear. Running core parts of the OS off of our USB Flash drive was an exercise in frustration and sluggishness. It’s hard to put a number against the feeling of responsiveness in an OS, but you know it when you see it and notice even more when you don’t see it. I was surprised to see how well the Flash drive did here, considering how poorly it performed everywhere else. However, the margin of difference here is very slight and non-existent for the 3 B+. Perhaps it’s no surprise that having faster storage would allow you to gather and send more data from the server to the client. ![]() Apache Web Service Test with Pi 4 and SSD
