Random Data Transfer by Size
We expect random reads to slow down as file size increases, since we're measuring IOPS. Thecus' N5810 Pro starts out with the highest 4KB random read IOPS, but drops below the other systems at 8KB, where it rides the low end of the group before merging back with other products at 32KB blocks.
The random write tests with increasing block sizes also shows cache affecting performance. The N5810 Pro fares well, even if it doesn't always outperform the other products.

You don't mention if it does data scrubbing to protect against bit-rot?Reply
Typically battery backups are SLA (sealed lead acid) which is most likely why they don't get packaged with NAS systems - they're heavy, they're a dangerous good by transportation and shipping rules, they expand and can release gasses when under load and charged. The upside? They have way more capacity than that of a lithium-ion as shown in this little unit, they (probably) cost much less, and they last longer (5+ years vs 2-3). In terms of a NAS though, the capacity isn't really an issue if the only thing the NAS is doing is shutting down to avoid data loss/corruption.Reply
What's the idle and load power draw for one of these?Reply
55.3W under heavy throughput and 35.1W at idle with 5x Seagate ST500DM005 HDDs and RAID 6 configuration.Reply
I'm not sure if I've just missed it - but: How many drives of what brand and capacity, in what raid mode were used for the testing?Reply
It would be good to single this information out into one of the section headings. It may be redundant as you presumably standardise this across NAS of a given bay capacity - but it would still be useful.
This is an impressive device. I'd definitively give it a try for home office solutions. The only downside I can see to it is that if the internal memory were to die (flash, ram), the backups are probably gone unless they keep using the same system/setting organization and it is forward compatible with other similar systems.Reply
5 years is a long time and unless they intend to have the same product line around for a long time, it will either be EOL or replaced with an updated version.
