Couple of question
I want to store my family pictures on a NAS, how much should I be worried about not having ECC?

In this video the USB limit 10Gbps is mentioned as the bottle neck, aren't a lot of consumer NAS with 10Gbps have the same limitation? Just wanted to understand as I trying to makeup my mind between NAS and a DAS.

For family photo storage, you do not need to worry much about ECC memory. ECC is useful for enterprise or mission-critical environments where data corruption from memory errors must be detected and corrected automatically. For normal home or photo storage, non-ECC memory is perfectly reliable, especially when combined with file systems such as Btrfs or ZFS that have built-in integrity checks.
Regarding the 10Gbps USB limitation mentioned in that video, that applies mainly to DAS devices connected over USB. USB 3.2 Gen2 (10Gbps) limits total transfer speed to around 1GB per second. A NAS with 10GbE networking is different because it uses a true Ethernet interface, which provides that full 10Gbps bandwidth across the network and is not shared or limited by USB protocol overhead.
If you mainly want fast, direct access for editing or transfers from one computer, a DAS is simple and fast. But if you want to access photos from multiple devices, phones, or remotely, a NAS is the better choice. It provides user management, backups, remote access, and redundancy features that DAS devices cannot match.
