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

If HDDs weren't cheaper i would only use SSDs. and yes, the cheap consumer stuff, like samsung 850 evo. Price is the only downside IMO.

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

I am not familiar with the kirkwoods that you mentioned. Just to be clear, the USB drive I was describing is rotating media in an external enclosure, not a memory stick. Generally self powered, as powering a portable hard drive from USB with a RPi is asking for trouble. I have stopped buying

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

The problem is the index. It is heavily updated, and I had a Fossil installation that ate my SSD in about 6 months. The log was OK, so I could rebuild the index on another disk. On Sat, Feb 3, 2018 at 10:39 AM, lchg wrote: > As I know, fossil/venti file system is

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

Hey, thanks for explaining. this usage is surprisingly valid. I have some much much older kirkwoods for the same scenario. The benefit is: gigabit ethernet, higher stability, case included, power supply included (and no power problems as on rpi), lower price. I boot them all from USB HDDs, but I

static web pages, remote login (so that I can power/depower other hardware) and file remote file distribution (via scp) mostly. The main requirement is very low standby power consumption so that it can survive on batteries which are recharged using solar panels. Power consumption was the main

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

For home use a ZFS intent log and caches on a good 2,5" SSD in a battery-backed thinkpad seems like an easy, silent, fast and stable (even against data loss from power outage) basis, even if you only connect shitty USB3 HDD drives externally for the pools. Your data should be safe on the SSD as

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
