Unfortunately I don’t think Verbatim manufactures any quad-layer discs, so Sony was the only real option for 128GB disks.

Furthermore, M-Disc is still very pricey per-GB, and their non M-Disc BD disks aren’t priced that much better. I’ve also recently got a spindle of Verbatim BDXLs that every single one would fail to either write or read at the layer transitions, so having a single option here is already proving to be painful.

Seconding this, while I have the option for multi-gig at my address, I don’t have the need, once you get around gigabit upload speeds life is fine.

I can upload hours of uncompressed gameplay to YouTube in under an hour, and that’s limited mostly by their ingest speeds (≈300Mbps) and not my end, so that’s plenty.

With all that said, the option for consumers is great, I’m thankful I have that choice, wish more people had it too.
