Even if you're not professionally freelancing, if you're in industry, the chances are you need a fair whack of storage that's both fast and reliable. There are a lot of solutions out there, but no matter which way you go, you're going to need drives.
I find the Backblaze statistics to be a very useful source of information when it comes to keeping abreast of bulk storage options, and their potential reliability.
It's worth keeping in mind that Backblaze have very particular needs, which may not mirror your own. But hopefully there's some useful information in there anyway, if you are looking at equipping, upgrading, or maintaining your storage arrays.
