I’m using my temp spare space for chia (as it will take at least 6 to 12 months for Storj to fill one of my drives)
At the moment everyone is “solo-farming/mining” chia so it’s a lottery with really, really bad odds…
Once Chia get pools implemented (expected end of month) it will be less of a lottery and more of a traditional pool-mining operation.
As for killing NVMe’s and SSD’s it’s a pain but their is a way around it of you decide to use old server equipment.
Grab a cheap SAS HBA card (around $40-50) and a hand full of dirt cheap 300/400Gb 10k/15k SAS drives (pick them up for $20-$30 each) and with a few RAID settings and you can get close to NVME speeds on spinning rust to do all the plotting with less cost than a 1/2Tb NVMNe.
it’s just another way to let your drives earn a bit of £/$/€ while wating for Storj network to fill your drives
