[9fans] SMART: Silly Marketing Acronym, Rebuts Truth

The interesting thing (for me) was that the SMART data from the drive gave it an all clear right to the end. But unlike the SSDs, there was plenty of behavioural warning to remind me to have the backups up to date and a spare at the ready... FWIW, of the three-four dozen or so drives I have

Re: [9fans] Is fossil/venti file system a good choice for SSD?

Thats why I described my use case - to make the MTBF figures meaningful. As I said, I have my system configured so that most heavy write accesses go to rotating media. I typically try to have my system partitions mounted read only, except var and tmp. I am currently using 32GB uSD devices for

Re: [9fans] Is fossil/venti file system a good choice for SSD?

My experience of running normal (read mostly) Linux filesystems on solid state media is that SSD is more robust but far less reliable than rotating media. MTBF for rotating media for me has been around 10 years. MTBF for SSD has been about 2. And the SSD always seems to fail catastrophically -

not so sure about mtbf. but it's too early to tell.

Re: [9fans] Is fossil/venti file system a good choice for SSD?

More the lidea of reading from the ssd first. The way fs(4) driver works is you order your drives with the first written at one end of the queue and first read at the other. I assume the read rate and rotational latency of an ssd should be better than hdd so I get the best performace. I should

Re: [9fans] Is fossil/venti file system a good choice for SSD?

what's the rationale behind writing to the hdd first?

Re: [9fans] Is fossil/venti file system a good choice for SSD?

i would say ssd is an excellent chiice for venti, the argument is less clear for fossil which us much more like a traditional filesystem. fossil and venti do not have the performance if a modern filesystem bur an ssd can make them fast enough for most use (i dont stream movies from my plan9

As I know, fossil/venti file system is log-structured, so it may be good for flash devices, especially in extending life of flash devices.
