Hello community,
We recently moved MicroOS and Kubic to use tmpfs for /tmp instead of writing files there to disk.
Right off the bat, +1 .. I have been using this since a long time..that said..
- Reducing wear on SSDs/SD card storage
This is actually a non issue with modern SSD devices.
Is it really? I'm doing ~3-4 bootstrap / test cycles of GCC a day each ending up with around 10GB of throw-away storage (but the actual amount of written data is higher). That's of course still far away of consumer-grade SSD write endurance, for example a 256GB Samsung EVO has 5 years warranty at 150TBW but that makes only 82GB writes per day where those throw-away bootstraps would be more than half of the specified endurance. So I'm doing those in tmpfs (w/ 32GB ram my tmpfs is limited to 16GB via manual configuration). [no, I don't actually own a 256GB SSD but a 512GB one where endurance tends to be higher] Richard. -- Richard Biener <rguenther@suse.de> SUSE Software Solutions Germany GmbH, Maxfeldstrasse 5, 90409 Nuernberg, Germany; GF: Felix Imendörffer; HRB 36809 (AG Nuernberg)
