Hi everyone,
So, I'm using some NFS mounts synced with FreeNAS, which currently are slow to a crawl, as the raid is simply 5 x 3TB HDDs
Due to that, I've seen around that adding a Log drive to the pool, which should dramatically help with this.
I've decided to go with an Nvme drive on my HP DL380p server and to achieve that I will be trying using an EZDIY-FAB NVME PCIe Adapter (the simple one, not the RGB versions lol).
My budget for the Log drive is up to 150€ max.
Right now the one I've been leaning to is an Intel Optane 800P 60G which I can get for around 140€ from Amazon Germany.
The questions I have are:
Also, If you have any other suggestion for other drives would be welcome, I was thinking on using my 960 Evo 250GB, but seems to have fairly high latencies.
And I don't need an enterprise battery powered Log drive, as the server is UPS powered, most of those drives even used in the market don't have great price to performance value.
Thank you,
Ralms.

The questions I have are:
- Will the Pool sequencial read and write speeds be limited by the Log drive?
- What is more important, read or write latency? or both?
- In an 15TB pool in Raid Z1, how much capacity is really needed on the Log drive? I heard is really low in the single digit GB.
