Doing a refresh of my RasPi5s. I think this is the right subreddit for this question. I debated /storage, but this sub seems more engaged for my type of question. Longer term, with the knowledge I hope to acquire in here, making some flash-nas.
By default, Rpi5 puts NVMe drives(PCIE link breakout board, not a HAT) in gen2 mode, you have to go out of your way(software config, nothing hardware) to enable Gen3. So, speed is really not that much of a concern. Out of the box, gigE is the fastest we are going for the time being, but maybe five gigabit adapters once software support is ubiquitous, and power draw isn't too dramatic. These drives will likely be "bonded" to the raspberry pi for the foreseeable future. re: not taking them out or swapping them. Actually, my whole goal is to never service them! re: TBW
I am open to Gen 4 drives, if the parameters in the title makes sense, etc. I'm aware, just like RAM, that my ideal drive might not be currently made anymore and a Gen4 might be "best". Right now, it just feels SILLY putting a $250 stick of NVMe into a RasPi... but times are changing I suppose.
I know TBW is not the only end-all factor for drive life. But it's the only publishable metric, that I have to go on and judge drives without hours or days of personal testing.
Workload/Context: RPi5 running HomeAssistant(base image is Ubuntu IIRC). Sounds silly, but 100, 1000+ sensors later, add some Containers/logging/etc. Fills up quicker than I was expecting. Ideally, these drives would also do some NNTP in their spare time. Or - It would be OK to pop one out and put it into a laptop, etc.
With all of the above, taken into consideration, what are some drives I should look at? I default back to my post title: Best TBW, price per TB, and thermals are last.
Sorry if I provided too much/little or redundant context. Thanks!
