For hardware reasons I don't want to get into (and have absolutely zero power to change), I need to set up an SSD over a USB-3 (type A) bus that is optimised for write performance.
In my use case, I'm expecting to write c. 250 files per second, each about 600KB, for extended periods of time (between 15 mins and three hours, say). That's a data rate of about 144MBps
I'm asking here because with the Samsung 850 EVO and PNY USB enclosure I have, I have been getting unacceptable performance. Even going to far as to have the drive unmount itself after a few minutes of heavy use (when it then remounts itself, but I lose the ability to write for a while).
My questions then (in what I hope is decreasing order of relevance for this site) are:
- What mount options should I be looking to use for this drive?
- The drive is currently ext4, is there any benefit to reformatting it differently?
- Is there anything else I can tune in my software configuration for performance?
If any of these are better asked in another forum, please point me in the right direction.
My distro is Ubuntu 16.04-based, arm64 architecture.
