Producers don’t publish the failure charge of their merchandise however BlackBlaze, one of many largest cloud storage service frequently publishes the failure rates noticed in its server farms. Regardless of what folks say primarily based on their private expertise, there isn’t a lot reliably distinction between producers. Some fashions had been notoriously dangerous up to now just like the 4TB from Seagate however precise statistics present related outcomes and each manufacturers might be equally trusted.

In any case keep in mind to at all times save your information on separate places reminiscent of totally different laborious drives or to the cloud. Hard drive fail and the chance of failure will increase over time.
