The system pool is used for dedupe (the backup kind not inline), app installs, etc, so using SSD’s for that is advised.
I thought the same thing, but the first two drives are used as SYSTEM drives - meaning where the default folders and apps are stored.
@dolbyman is correct - The OS is installed across all drives.
If your main use is storage and you don’t run many apps the lower power TS-h886 (still a current model) will probably be your best bet.
For reference the Xeon d1602 cpumark is 2459. The Xeon d1622 cpumark is 6205. 2.5 times as fast. While cpumark is not the best indicator of overall NAS performance, you can see why in our case, it made a huge difference.
ok, still useful then at least. I guess now I have to decide if ZFS is worth it or not.
Well, ZFS does have advantages. WORM is pretty sweet as are things like the inline compression and deduplication. It can save a lot of space.
I don’t know about speed of ZFS over EXT. Probably the same. I do think that the ZFS format does leave you with slightly less drive space.
Ok, well for now I don’t think I’m ready to upgrade the hardware for another 1-2k, so I’ll wait this out. Major bummer though. I think there should be a really clear list from QNAP of where Hero is supported, annoying to say the least but also my own fault!
Again, keep an eye open on eBay. I found my second NAS that supports here for a few hundred dollars as I already said. You should be able to see what NAS devices support Hero on the QNAP site. it’s there.
QTS is faster for sequential file transfers (typical home file server usage), especially on lower end models with limited RAM. Scrubbing should still be done at least monthly with QuTS as well.
In addition to the model lines that have a “h” in the name, I know of at least these models TVS-X72 (as mentioned you need to make sure it’s from late production), TS-X55, TVS-675, TS-X73A and TS-X53E (only 2 and 4-bay though) that run QuTS Hero. TS-X55 and a late TVS-X72 with at least a core i3 CPU are the only ones I would recommend and I’d say 16 GB RAM is a minimum for ZFS.
