Did you buy them? I wouldn't be comfortable with that. Sure, I hope BURST (and some clones) makes it, but the investment must be very high risk atm and the ROI longer than the warrenty of the disks.
Yes, I bought them. The investment isn't too risky, I don't think.
I'm expecting a return in about 24months, most of which is covered
by warranty. Lots of other options for data storage too with Storj,
Sia, Maidsafe e.t.c
I guess only time will tell.
