Ubuntu Server with bcache

[rewird]

Hey all =)

 

Ive been doing some research on bcache for a nas/webserver setup.

 

Most tests i've seen have only shown marginal improvements with a SATA drive; Is it possible to use a partition of my nvme boot drive as a 60gb bcache for a 2TiB Sata drive?

 

If it is, is it even worth the effort? The plan was to have general use files in the 2TiB drive for web stuff and dev projects.

 

Thanks =)

Nvme won't help. 

 

Your limited by the caching program and amount of cache not the speed of the cache. 

 

I'd just use a standard hdd and separate ssd.

ive been trying to find recommendations of ratio for the size, but so far only seen 128gb ssd's used. Would this mostly be for cost or?

Depends on how your using your data

 

A cache can be useless if your not using the same data multiple times. For a nas a cache won't help if your on a gigabit network. 

 

For basic dev work I'd just use that hdd you don't need the extra speed.
