Spinning disks still have their uses though. For example, they're ideal for a low-to-moderate amount of disk activity, and they last longer. Just make sure you schedule a daily defragment. Spinning disks are also great for 'cold storage' of files. I wouldn't store anything worthwhile on an SSD though because of their fail-rate. SSDs of course have their use cases too, but there are many trade-offs to using them exclusively for everything. I know people who exclusively work with SSDs naively thinking they're a progression from spinning disks. Not actually the case!
