I just wanted to see if it was faster... And.... It is. I order the cheepist mSATA 5030MM 480GB by TOROSUS and the Geekworm Raspberry Pi 4 mSATA SSD Adapter. The Micro-SD is a Samsung Evo Select 256gb. All from amazon.com I started with the normal flashing to the 256gb Micro-SD. Pretty Simple. It Booted right up. I did the setup and stuff like that (wifi, blah, ect). I just cloned Micro-SD ext4 partition to the SSD and expanded it, cloned the FAT32 partition to a spare 2gb micro-sd card i had, with gParted. I had to fiddle with the on the SSD and the file in the Micro-SD. And did a search to find out how to get PARTUUID (as UUID is not the same) for the new clones as gParted changes them. /etc/fstab cmdline.txt And YAY I got it to boot using the SSD. So lets get to the results! Results with the Micro-SD, Samsung Evo Select 256gb pi@raspberrypi:~/workspace/testFS $ sysbench -- =fileio --file-test-mode=seqrewr run sysbench 0.4.12: multi-threaded system evaluation benchmark Running the with following options: Number of threads: 1 Extra file open flags: 0 128 files, 16Mb each 2Gb total file size Block size 16Kb Periodic FSYNC enabled, calling fsync() each 100 requests.

Thanks for the Read! UPDATE: August 2020 Well its time for a update, So today I decided to update my Pi setup. I recently seen there was eeprom updates for USB Boot Support for the Raspberry Pi 4b @ , So I decided to give it a shot!. github.com~rpi-eeprom-firmware/release-notes.md I found a guide , Using same mSATA 5030MM 480GB by TOROSUS Here I changed out my USB/MSATA adapter, to a 10$ one i found on amazon. @ https://www.amazon.com/~/dp/B075FR3ZD4 So here is the new Results! pi@raspberrypi:~/workspace/benchmark $ sysbench --test=fileio --file-test-mode=seqrewr run sysbench 0.4.12: multi-threaded system evaluation benchmark Running the test with following options: Number of threads: 1 Extra file open flags: 0 128 files, 16Mb each 2Gb total file size Block size 16Kb Periodic FSYNC enabled, calling fsync() each 100 requests.
