Sounds cool for long term data storage, but they need to get the read write speeds up.

4mbps write and 30mbps read is extremely slow. Even if they achieve their roadmap 500mbps is still slow compared to modern drives.

Better not keep any data you need access to within like 90 days on it or you're toast.

What market is this even aiming for? Bitcoiners?

Long term storage, along the lines of tape replacement/supplement?

There are plenty of things that need to be archived in a basement and never read unless the more readily available forms get corrupted.

Having the ability to say as long as the item exists the data exists is valuable, especially with not having to worry about degradation (which happens with tapes/flash/hard drives)

The ability to say that the data is good.

> 4mbps write and 30mbps read is extremely slow.

It's even slower when you consider the 360 TB capacity -- it'd take nearly three years to write to the whole thing.

The better question is the seek latency. The bandwidth for read isn’t too horrible, if the seeks can be kept within reason. This is somewhere between tapes and actual pressed optical media (not dyed /re/writeable). Should seek way faster than tape (maybe even on par with BluRay) and 30Mbps read is manageable for doomsday scenarios.

Long term databanks. Libraries. GitHub’s archive bunkers. Microfilm replacements.

at theoretical perspective, if the X-Y plane can be addressed with 16-bit DAC by controlling laser deflection. then to seek any data with in a 4GB address space will have typical latency of 300us with the latest laser scanning technology.

I am not aware any laser scanning technology that can do 16-bit accuracy that has no moving part. so, fundamentally, this is a storage technology with mechanical addressing.

laser can be scanned by acoustic wave, but that itself lack the beam pointing accuracy. the ultrasonic drive frequency will limit how fast is can deflects the laser beam.

Had to go back to the article to see the actual speed units. Above commenter meant MBps (Megabytes/second), not millibits/seconds nor megabits/second.
