Really? With the cost of SD cards what they are? Like, I can get a 128GB SD card for $30.

That would be 170 CD’s - nearly 30 DVD’s - which will eventually suffer disc rot.

DVD/CD write speeds are very slow, comparatively speaking to even USB 2.0 transfer speeds - and increasing the speed, in my experience, makes exact copies of discs extremely error-prone.

Explain how this is efficient? Genuinely curious, with the price of solid state storage these days.

(I understand even solid state storage has a shelf life, but at least it also can’t be so easily harmed as a CD/DVD)
