That's true, but this is considerably more convenient than traditional tape. Tape as is requires specialty equipment and careful handling, if I understand the above product proposition correctly, it's just plug and play. Right now, only an enthusiast would use tape in their home setup, with this approach, anyone could use it for their backup server or w/e.
But, "never underestimate the bandwidth of a station wagon full of hard drives".
The intriguing use case (thinking as a consumer) is ~2tb "hot", and effectively treating the remainder tape as kindof "append-only/WAL" (and: e.g. incremental backups).
I have been randomly ripping my DVDs, mostly keeping the transcoded MP4s, but hesitant to delete the ISO's because they require physical handling and _time_ to re-rip.
If it's ~2min to seek to an 8gb ISO, that's potentially faster than re-downloading it from somewhere offsite, and would match my hypothetical use cases really well.
Keeping a local ~2tb drive backed up to a ~4tb+40tb "ssd-tape-hard-drive" is probably cheaper than most long-term cloud stuff (backblaze ~$6/tb/mo!!, glacier ~$4/tb/mo, but with lots of asterisks on retrieval time), and simpler than messing around with a NAS.
