Thanks for the clarification… While I understand eMMC in general is less reliable than SSD, my reasoning for wanted to install TrueNAS OS on it is because that’s where the Ugreen NAS OS is/was installed (UGOS). I’m kinda going by assumption that both OS’s would wear out the eMMC drive more or less the same, and Ugreen wouldn’t have put their OS there if it was an unreliable eMMC. But yea, an SSD would definitely be better - 100% agree.
Surely by the time the emmc has worn out it would have been many several years anyhow, perhaps by then you would have replaced the nas with a better one.
Doesn’t most of the work, happen in ram and maybe VMs/dockers can be stored and run from the nvme or ssds.
Most of these mini nas pcs come with emmc, I guess if it did wear out suddenly after 2-3 years you could then move over to an ssd or nvme and sacrifice ports/storage etc
asked dr google:
The estimated life of eMMC can also be influenced by the amount of data written to the device. For example, if a user writes 10 GB of data per day, the eMMC may last for several years depending on its capacity and the number of P/E cycles. In automotive applications, where eMMC is used for long-term reliability, the storage is designed to handle up to 10 years of use.6
In practical terms, eMMC can last for at least 10 years under normal usage conditions, but the exact lifespan depends on the specific device and how it is used.5 Some users have reported that lower-quality eMMC in budget devices may fail sooner, especially if they are subjected to heavy write operations.
