Is 10G worth it for 8x8tb 5400rpm RAID6 w/ 2tb SSD cache? (alien.top)

I am investigating upgrading to a 10G network card in my TS-873 with 8x8tb (seagate 5400rpm shucked from easy stores) Raid 6 and a 2tb SSD cache with the goal of editing photos and videos directly from the NAS instead of managing files locally.

What I am unclear on is what the max speed I would be able to achieve on my system would be and whether I would even get close to saturating 10Gbe/5Gbe/2.5Gbe. Obviously prices for 2.5gbe equipment are way lower so if I can't get faster than 2.5 I'd prefer not to waste the money on 10gbe equipment.

seems can go more than 2.5Gbps https://redd.it/121sxom

Thank you I saw this thread too. My drives are a bit slower at 5400rpm and most commenters there have 7200rpm and raid 5 which is a bit faster than my raid 6. Also I wasn’t sure how ssd caching helps if at all.

You'd need 10gb on the nas, switch, and computer, or the transfer speed will be equal to the slowest component between them. But whether you'd get that full performance comes down to the speed of the disk controllers on the nas. You either have to find some performance reviews of this exact nas, or cross your fingers when you test it out.

Yes my plan is to get an ax89x which has 2 10gbe ports, a 10gbe card for my nas, and a 10gbe adapter for my MacBook. With only two devices no need for a switch. Good point on reviews I will look around.

Use NVMe as cache and the 10G will be 100% used.
