 Dear All:
 Indeed, the topic is not simple. But considering the reliability of RAID, the
 crucial parameter is URE (unrecoverable read error rate) of the hard drives.
 This is especially important for big drives, like 6TB or larger.
 You can read more about URE and RAID on the net, for instance here: https://www.raid-failure.com/
 Best wishes,
 Mariusz

 an individual.  If your institution is affiliated with the OSF, perhaps the
 price is different.

 in the cloud.  I will retain a backup on an external hard drive, which I will
 keep at home.  But I'm looking for an additional backup in another location (the
 other location being, ideally, the cloud).  These files are not themselves MD
 trajectories from my PhD, but rather are output and analyses related to the
 trajectories.  (The trajectories themselves are tens of TB and are being
 retained, for now, by my university.)

 transferring ~1.5 TB to the cloud is itself a nontrivial task, but I'm willing
 to see what the options are.
