9200-8e vs 9300-8e - 6Gpbs vs 12Gbps Reality

[Seed]

Hello,

I currently run a 9200 HBA card to an external raidz2 pool in an enclosure that supports 12Gbps SAS. Would I see a benefit upgrading the card to a 9300 that supports the same? I'm running 10Gbe and move a ton of files and run a ton of services on this pool so wondering if it's really worth it.

Maybe.

What do you have attached to it?

If it's SSDs, certainly.

If it's HDDs, maybe,but probably not much (unless it's a large number of HDDS)

I currently run 9 7200 WD Reds in z2 but will be rebuilding the pool to a 12 disk, 6x2 vdev pool, maybe a 4x3 pool. Data is backed up off this host so not too concerned on high resiliency if a 3 vdev is good for IO. I want to direct edit off a Mac mini on this host on the HDD shares

Direct editing is likely to bottleneck on IOPS as you scrub the video (assuming that's what you meant by direct edit).

Maybe mirrors will be the option if you need IOPS, but also note that SMB on Macs may be requesting Sync writing, so you'll need to consider disabling sync on that dataset or having SLOG (and siutable amounts of RAM) for that to not suck a lot.

Your existing card won't be a blocker for IOPS (nor throughput with that number of disks), rather the HDDs and pool layout.

Ok I’ll do some testing. The card isn’t that expensive so may as well get it and swap it out anyway and can keep the 9200 for back up. Thanks for the info.
