On the pro side: BackBlaze has always focused on making their tech lean and agile enough to stay profitable while they hit that low pricepoint. Most users don’t use much in terms of HD space for their backups so they can absorb the extra cost for people who back up large amounts and since they are using their own lean-focused servers with consumer drives their cost per TB is much lower than a company backed by S3. They are also the company that puts out drive stats every quarter. And they open-source the hardware for their rack-mount “pods”. They also added another revenue stream: B2. It’s an S3-compatible storage service with a decent profit margin that still manages to be 1/4 the cost of S3. TL;DR: They have a solid business model built around providing that low price.
