Use SSD as cache in samba server

[Zvon]

I am running Debian from a flash drive on an old laptop with an external HDD as a NAS. The laptop has no internal drive. If I were to put SSD in there would it automatically use it as a cache? (when I upload files they would first upload to SSD and later to HDD) And if not could I somehow achieve this?

You can use bcache to do this.

 

For most uses, the ssd cache won't help at all in a normal hone nas.

i have not seen evidence that SSD cache in a home network with gigabit speeds offers any benefit. I think the benefits are in running SQL databases.

thats not quite what the cache would do. It will cache regularly used files not one off ones.

I guess you're right about it being kind of useless, I just thought with all the black friday deals I might try something like that. But I guess it would be a bit more sensible to just save up a bit and build a nas with internal drives, so it wouldn't be throttled by USB 2.0 speeds.
