My first thought went to those M-Disk/BDXL bluray disks which supposed to last 1000 years if you believe the claims. So with 100gb per disk you would need atleast 1000 disks. Probably more since the data probably wont perfectly fill out each disk. Writing to optical media is slow and according to the very first searchresult i found it takes upwards of 3hrs to write and verify a single disk. So with a single drive it would take atleast north of 3000 hours if nothing goes wrong. A year has ~8760 hours btw. Oh boi.

But i wouldnt want to rely on a single copy of each disk. If the data is so important i would like to have atleast 10 copies? So the year would probably consist of only maintaining and repairing several burning rigs and going through like 35.000 edit: 11.000 blurays and then finding spots to safely store them.

But how will they read the data of the disks in the future? Blurays and todays data formats most likely wont exist anymore. So you would need several redundant PCs with bluray drives which hopefully last that long. The HDD/SSD wont last in them. Linux live disks burned on the blurays? On top foolproof documentation how to operate all that ancient shit.

My head hurts

Motorola G100/Edge S

Atleast here it can be had for under 200€ on the used market.

You need to unlock it via the motorola website. But then its fully rootable. Atleast with the retail unit i purchased.

Buildquality is good. Nothing fancy. Its mostly plastic. But it holds up quite nice after 4 years. The chromed plastic of the frame flaked a bit from my rough handling.

Removable sim and SD-card slot. Battery isnt removable. But its not the worst when it comes to repairability according to teardowns i watched.

But it has a headphone jack!(!!!)

Runs officially up to android 12. Last time i checked it should get android 15 with lineage.

Security… well there is only so much lineage can do with the official vendor support beeing ended like 2 years ago. But its good enough i guess.

That 21:9 1080p 90hz LCD screen is solid. 500 nits brightness isnt state of the art anymore but its more than useable.

Qualcomm Snapdragon 870 combined with 8gb RAM is still performing well. If your into emulation it handles most of the consoles well. Even switch and pc emulation apart from the most performance hungry titles.

Cooling isnt the best. Its just a heatpipe from the SOC directly too the battery. SOC will heavily throttle as soon as the battery gets to around 40 degrees C. That nets you around 20-30 minutes of the SOC running at full tilt.

USB 3 5gbs with display out is a really cool feature. Sadly with going custom rom you will loose the great ‘ready for’ desktop mode from motorola.

Its a bit big and heavy for my taste though. I switched to a smaller device as my daily driver.

All in all its great device for screwing around imho
