So right now I'm backing up 80gb of data to Google Drive for $2 per month. Switching back to SpiderOak would allow me to add my media collection that I always considered too large to back up online.<p>But is this SpiderOak plan sustainable? Let's say the average person who gets this plan backs up 500 GB in the first month. Hard drives cost ~$0.04 per GB, so that would cost $40 to store assuming they store it on 2 drives. Let's double it since we're estimating, add a bit for bandwidth, and it seems doable.<p>As long as people don't keep backing up more and more year after year, that seems pretty sustainable, since they keep getting $125/year.<p>I guess I should sign up.
Somewhat surprising move considering their earlier statement[1] on unlimited storage. Still, my renewal is coming up soon anyway, so the extra 25$ (against the 100$ annual for 100GB) doesn't seem like a bad deal.<p>[1]<a href="https://spideroak.com/blog/20110202135038-whaaaat-unlimited-storage-for-499-a-month-not-a-viable-business-model" rel="nofollow">https://spideroak.com/blog/20110202135038-whaaaat-unlimited-...</a>
