Interesting which is cheaper to produce. I have no idea about wholesale prices, but let's look at retail to get a rough ratio: 10 DVDs at retail cost $25 https

Interesting which is cheaper to produce. I have no idea about wholesale prices, but let's look at retail to get a rough ratio: 10 DVDs at retail cost $25 https://www.amazon.com/Verbatim-DVD-R-4-7GB-Recordable-Media/dp/B003ZDNZT2/ref=sr_1_2?dchild=1&keywords=100+dvds&qid=1594930720&sr=8-2 https://www.amazon.com/Verbatim-DVD-R-4-7GB-Recordable-Media... So $2.50 for 10 discs. An unbranded 128 GB usb stick is $16 https://www.amazon.com/SanDisk-Cruzer-128GB-Flash-SDCZ36-128G-B35/dp/B00TKFCYP0/ref=sr_1_3?dchild=1&keywords=usb+stick+128gb&qid=1594930866&sr=8-3 https://www.amazon.com/SanDisk-Cruzer-128GB-Flash-SDCZ36-128... Assuming the box will be about the same size, it's likely that the DVDs are simply still cheaper. An interesting lament is that disk media did not really evolve past DVDs to blue-rays or multi-layer to the mass consumer market, as 100GB blu-ray discs are actually available (still more expensive per-GB than DVDs!) https://www.amazon.com/Verbatim-100GB-White-Inkjet-Printable/dp/B00POY826G/ref=sr_1_1?crid=224DK5Z66DFRK&dchild=1&keywords=100+gb+blu-ray+disc&qid=1594931021&sprefix=100+gb+blu-ray+disc%2Caps%2C165&sr=8-1 https://www.amazon.com/Verbatim-100GB-White-Inkjet-Printable...
