Have a new iPhone or iPad? You’ll get one Lightning cable with it, perhaps too short or too long for what you’d like, and likely to fail over time (my kids are really good at killing Lightning cables!)
I like to keep extra Lightning cable on hand. For example, I cannot afford to have one fail while traveling, plus I like to keep one plugged in on my desk and in my photography van. And then the kids want one when they break 'em.
The Apple Lightning cables have performed poorly for me—every one of them has failed.
The most durable Lightning cables that I’ve found are the NewerTech ones, and they come in a variety of colors and lengths. They can fail also (with abuse), but they have performed well for me. Other brands I cannot attest to.
One internal drive and no backups—yikes! Too many people forget that two backups are a bare minimum.
