@grawity_u1686 : ... That's right. I can buy 4TB EVO 870's just 330USD in my country, and 4disk with RAID5 served reliabilty and high-performance. I use only one client in my wired network and NAS service, My complaint was that it took a while to read 24MP JPEG photos and video browsing experience that wasn't the same as local.

@Bob : My NAS can SSH, but However, complex tools are difficult to use by NAS CPU and my knowlege.

@Journeyman : My wireless latency is short enough to be negligible.
