Well bugger. I've come to learn that my NVME SSD's I brought only have a 400TBW (total bytes written) rated lifespan.

I fear that running a Hivemind instance on my computer with these drives may be a bad idea in the long run. Especially if I have any failures that would require a resync (which involves a lot of writing)

My current primary nvme is already got 243TBW used up after a little over a year of use. This is partly due to inefficient recovery of my Hive witness node (I would redownload or copy the whole blockchain @ 500+gb a time, now I just trim off 1GB and redownload that)

So cutting out the constant blockchain downloading i've done my drive could probably lost quite a while. But at £200 a drive... ugh..

I may end up building a SSD RAID 5/6 storage rack hooked up via ethernet in order to run a full node from home.
or i could rent a server...... but that's no fun.

Dam that sucks, That is the downfall to the SSD is the write life, I am thinking that is something that needs a fix as it is going to cause mass amounts of waste.

Best of luck building a hive fullnode at home haha

It turns out this just this particular SSD the Q-NAND tech has a lot less lifespan than traditional TLC chips but the performance is insane.

I'm not 100% sure how hard hivemind would hit these kinda SSDs and also I probably don't need this much speed, so I'm thinking building a regular SSD raid array would be a better bet and would also be cheaper per TB storage than what I got now, I'll use these 3 drives as like. storage for my games and stuff.

My worst one is with 280TB but has 600TB lifespan...

The trick is using lots of memory to avoid disk writes =) (aka disable paging spaces, and on windows use a lot of memory, and if possible disable paging space file).

Or hit the massive sequential writing on normal rotating disks... and care less for it. =)

I generally don't run swaps on my linux vms anyways since I have plenty of ram to give them. But anyways certainly going to just make a NAS with raid 5/6 long life SSDs, should be able to strike a balance between lifespan and speed.
