HDD question

[newazoro]

Hi, I have 8x14TB drives, they get about 210MB/s R/W. What setup should I be going with if I am looking for maximum speed?
I will be running TrueNas, thanks in advance.

If you are counting speed as throughput (since you mention MB/s) and you only have a single client, you would go for a RAIDZ2 with all 8 disks.

If you have many (or more than a couple) of users, you might want to consider IOPS as a factor and think about Mirrors and potentially SLOG if you're worried about block storage performance (not only large file copy speed).

If your data is a mix or even contains areas of high numbers of small files, doing something about metadata will be sensible to make sure you don't feel like your server is slow when it's processing them, like maybe a special/metadata VDEV or metadata only L2ARC.

I won't go much further in terms of recommendation without hearing more about what you actually want the system to do.
